As a high school senior, he won the North Carolina Plymouth Troubleshooting Contest \u2013 Written Skills, in 1978. Post high school, he worked as a transmission technician and builder at a GM Dealership from 1978 \u2013 1982. In 1982 he assumed the operational control of the family business and ran it until 1987. He began teaching automotive classes, part time, at Richmond Technical College in 1986 and soon discovered his calling to teach full time. In 1987, he took the position as automotive department head and instructor at Nash Community College in Rocky Mount, NC. In 1990, the opportunity to become a GM ASEP instructor led him to follow his passion to Greenville, SC and teach at Greenville Technical College through 1999. He returned to his roots late in 1999 as a transmission builder until industry came calling in 2001. Keith then took the position as the NC \/ SC regional Instructor for AC Delco through 2006. Next, he became an AC Delco Market Area Service Manager until 2008. His next assignment was Regional Supervisor managing the AC Delco Southeast Region until 2019. In 2020, Keith completed his bachelor\u2019s degree in business management graduating from Southern Wesleyan University \u2013 Magna Cum Laude. In 2020, Keith took the position of Southeast Regional Instructor and serves in that capacity to the present day. Throughout his GM journeys, Keith has acted as project leader, writer, and subject matter expert in many of the courses that he and others have delivered to the nation. Keith is the proud father of four children (all college graduates), four grandsons and three granddaughters.<\/p>\n\n                                <div class=\"session-brief\">\n                        <div class=\"session-title is-style-h6\">HVAC Controls, Diagnosis and Service Techniques<\/div>\n                        <p><strong>01-21-2027 | 8:00-11:15 a.m.<\/strong><\/p>\n\n                        <p>\n                            This seminar will provide technicians with the diagnostic techniques and strategies required to diagnose non-refrigerant related issues with the HVAC electronic controls that impact electronically regulated compressor operation and the air delivery system.

In 2008, she opened the STEINBAUER North America office, spending the next fifteen years travelling between Europe and the US before making the permanent move in 2024.<\/p>\n<p>In her role at STEINBAUER, Sherie travels to approximately twenty states each year, working directly with farmers, contractors, service shops, and independent mobile repair technicians who depend on heavy equipment \u2014 giving her a ground-level view of what data access restrictions mean in the real world, not just in policy documents. That same firsthand experience sparked her interest in Right to Repair in 2019, and she has followed the issue closely ever since, delivering talks and presentations on the subject across the industry.<\/p>\n\n                                <div class=\"session-brief\">\n                        <div class=\"session-title is-style-h6\">Certified, Not Locked Out: The Right to Repair Argument<\/div>\n                        <p><strong>01-21-2027 | 8:30-9:00 a.m.<\/strong><\/p>\n\n                        <p>\n                            Heavy Duty Behind every truck that can&#8217;t be diagnosed is a fleet manager losing uptime.

The Right to Repair debate affects everyone in the chain \u2014 the operators and fleet owners who buy the equipment, the service providers who maintain it, and the trainers and businesses who support the industry around it.<\/p>\n<p>This session takes a solution-based look at where diagnostic data access stands today \u2014 the legislation, the landmark John Deere FTC settlement, and the real cost of the current model across the service chain \u2014 and then shifts the conversation to where it needs to go: a middle ground that works for everyone.<\/p>\n<p>If you&#8217;re a service provider,

V2X.com<\/p>\n\n            <p>Keith Glasgow was born and reared in the small town of Rockingham, NC, where he grew up in an automotive family that operated a general repair facility. As a high school senior, he won the North Carolina Plymouth Troubleshooting Contest \u2013 Written Skills, in 1978. Post high school, he worked as a transmission technician and builder at a GM Dealership from 1978 \u2013 1982. In 1982 he assumed the operational control of the family business and ran it until 1987. He began teaching automotive classes, part time, at Richmond Technical College in 1986 and soon discovered his calling to teach full time. In 1987, he took the position as automotive department head and instructor at Nash Community College in Rocky Mount, NC. In 1990, the opportunity to become a GM ASEP instructor led him to follow his passion to Greenville, SC and teach at Greenville Technical College through 1999. He returned to his roots late in 1999 as a transmission builder until industry came calling in 2001. Keith then took the position as the NC \/ SC regional Instructor for AC Delco through 2006. Next, he became an AC Delco Market Area Service Manager until 2008. His next assignment was Regional Supervisor managing the AC Delco Southeast Region until 2019. In 2020, Keith completed his bachelor\u2019s degree in business management graduating from Southern Wesleyan University \u2013 Magna Cum Laude. In 2020, Keith took the position of Southeast Regional Instructor and serves in that capacity to the present day. Throughout his GM journeys, Keith has acted as project leader, writer, and subject matter expert in many of the courses that he and others have delivered to the nation. Keith is the proud father of four children (all college graduates), four grandsons and three granddaughters.<\/p>\n\n                                <div class=\"session-brief\">\n                        <div class=\"session-title is-style-h6\">HVAC Controls, Diagnosis and Service Techniques<\/div>\n                        <p><strong>01-21-2027 | 8:00-11:15 a.m.<\/strong><\/p>\n\n                        <p>\n                            This seminar will provide technicians with the diagnostic techniques and strategies required to diagnose non-refrigerant related issues with the HVAC electronic controls that impact electronically regulated compressor operation and the air delivery system.

Attendees will learn how transitioning from traditional engine-belt-driven units to 12V and 24V electric compressors provides independent climate control, keeping operator cabs cool even when the diesel engine is idling or switched off. The session will highlight critical design considerations, including thermal management, vibration resistance, and smart power management to safeguard battery health in harsh agricultural and construction settings. Finally, real-world case studies will demonstrate how these low-voltage systems reduce overall fuel consumption, lower engine emissions, and simplify installation across diverse heavy machinery platforms.<\/p>\n<\/div>\n                <\/div>\n            <\/div>\n                                        <div class=\"session\" data-hd=\"true\" id=\"session_876\">\n                                <div class=\"session-speakers\">\n                    <div class=\"session-speaker\">\n                                                <img loading=\"lazy\" decoding=\"async\" width=\"666\" height=\"1000\" src=\"https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021.png\" class=\"attachment-large size-large wp-post-image\" alt=\"\" srcset=\"https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021.png 666w, https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021-200x300.png 200w, https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021-250x375.png 250w, https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021-511x768.png 511w, https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021-533x800.png 533w\" sizes=\"auto, (max-width: 666px) 100vw, 666px\" \/>                    <\/div>\n                <\/div>\n                                <div class=\"session-details paragraph\">\n                    <h4 class=\"flush-bottom\">ADAS Fundamentals: What it Takes to Calibrate!<\/h4>\n                    <p>9:45-10:15 a.m.<\/p>\n\n                    <div class=\"session-speaker-bio-links\">\n                                                                                    <a href=\"#\" class=\"is-style-h6 read-bio\" aria-controls=\"bio_modal_570_60\" id=\"read_bio_570_60\">Denis White<\/a>\n                                <div class=\"speaker-modal\" id=\"bio_modal_570_60\" aria-modal=\"false\" aria-label=\"Denis White Speaker Bio\">\n    <div class=\"top\">\n        <p class=\"is-style-h6\">Speaker<\/p>\n        <a href=\"#\" class=\"close-bio\">\n            <img decoding=\"async\" src=\"https:\/\/macsmobileairclimate.org\/conference\/wp-content\/themes\/macs\/img\/icon-x.svg\" alt=\"close modal\">\n        <\/a>\n    <\/div>\n    <div class=\"main\">\n        <div class=\"headshot\">\n            <img loading=\"lazy\" decoding=\"async\" width=\"666\" height=\"1000\" src=\"https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021.png\" class=\"attachment-large size-large wp-post-image\" alt=\"\" srcset=\"https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021.png 666w, https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021-200x300.png 200w, https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021-250x375.png 250w, https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021-511x768.png 511w, https:\/\/macsmobileairclimate.org\/conference\/wp-content\/uploads\/sites\/2\/2026\/08\/Denis_White_TEXA_121525_TER08021-533x800.png 533w\" sizes=\"auto, (max-width: 666px) 100vw, 666px\" \/>        <\/div>\n        <div class=\"bio-details paragraph\">\n            <h2 class=\"flush-bottom\">Denis White<\/h2>\n            <p>TEXA EDU MANAGER | Texa<\/p>\n\n            <p>40 Year veteran of the automotive industry, focused on training technicians for the last 10 years.

Se hace especial hincapi\u00e9 en los procedimientos del fabricante, la prevenci\u00f3n de riesgos, la responsabilidad medioambiental y la protecci\u00f3n tanto del t\u00e9cnico como de los componentes el\u00e9ctricos sensibles del veh\u00edculo.<\/p>\n<\/div>\n                <\/div>\n            <\/div>\n                        <\/div>\n        \n    <\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_acf_changed":false,"inline_featured_image":false,"footnotes":""},"class_list":["post-29","page","type-page","status-publish","hentry"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.6 -
