Electrical issue? 2005 Yukon

[Jay R Lawson]

my heat will blow but not hot. My fog lights don’t work. Air conditioning blows but warm. Windows will work then not. Then work. Air bag light on. Stability will turn on and off. If I shut the truck down most times these will reset. What am I needing to replace

Check your battery cables jay. By check i mean, pull them off, clean with a wire brush the reinstall with some dielectric grease. Also check all your ground cables, batt to frame, frame to motor...etc. A/c may need to be recharged and may not be related, may be coincidental.
