The rear AC is blowing hot air when the front is cold why ??
2003 GMC Yukon XL Denali Question: The rear AC is blowing hot air when the front is cold why ??
I just realized yesterday on my Yukon Denali 2003 that A/C in the front is cold but the rear blowing Warm or sometimes hot air. For 2-3 minutes it blows cold air in the back then back to heat or natural air. Any reason why?? It has 93K mileage - siseid
