In this video we will diagnose an intermittent cruise control problem that is tied to high outdoor ambient air temperatures. A seasonal problem when its hot outside that is due to an aging electronics defect resulting in random disengagement, intermittent cutout, or failure to engage at all depending on the outside weather temperature conditions.

The truck illustrated is a 1998 Chevrolet K2500 Cheyenne with the 5.7L vortec engine option, but the procedure and part numbers I share with you will be the same for any 1995 thru 2002 GMT400 generation OBS truck or SUV with a gasoline fueled engine. So Chevrolet, Cadillac, and GMC for Tahoe, Yukon, Suburban, Silverado, Cheyenne, Escalade, Sierra, and W/T across C1500, K1500, C2500, K2500, C3500, and K3500 weight ratings.
