Question about 1998 GMC Jimmy
Blows heat all the time no matter where i set temp control,also a/c isnt working
We had the same problem in our 98 GMC Jimmy. Was blowing hot air everywher with everything shut off & air conditioning would not work. We found out it was the Blend Dood Actuator, it is located behind the glovebox. We purchased one on EBay & replaced it and are back on track again. Good luck!
