Anybody have the 5.3 tahoe. My trk 2001 overheating issues. However its not overheating someone solve this issue. Constant un-plug/ plug back to reset. Tks for any insight. Tony here

Coming fans will not turn on when the truck is running. Only when the truck is off. I've replaced the coolant temp sensor and all cooling fan relays and fuses. It's making the computer think it's over heating so the truck acts like it's over heating even though it isn't.

Rear a/c works like it should but gets hoe when nor moving.
The front a/c won't turn on until i hit 20mph but stops when under 20mph
I dont know if it is the blower motor or the A/C system overheating.
