Ok guys I have an HVAC pet peeve. Search function no help. unless i missed something. Just redirect if I did.
The heat/ac will decide on it's own if I am to hot or to cold and turn it self on to max settings either way hot or cold. It will happen any random time highway,lowspeed, hot, cold, wet dry. it does not coinside with out side temp. it could be 80 and the heat will come on it can be 50 and the ac will come on. Temp readin is accurate not stuck at 50 like when the temp sensor shorts.
I have pulled the interior temp sensor out of the sail/b pillar, it is clean and connection good, no loose pins and did the same for the the exterior temp sensor.
Not having access to a TechII and Alldata any longer. part of me thinks there is an update/reflash for this. Does anyone know if there is or can run a search for me. Because if I had the info I could call around to some locals and see about having it done. I may just throw a 8$ exterior temp sensor in and see what it does. Because i will be damned if I let anyone else touch my truck especially the general. I left the Auto repair industry after 25 years and it sucks to have to have someone other than myself work on It.
