Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Is it that the AC is not cold or is the fan not blowing the air out?
Please let me know...
What I would like you to do is see if you can locate the aux.cooling fan relay in the the fuse block under the hood.
Once you find the relay, with the key in the ignition in the run position, turn the rear blower on and remove the aux. relay. When you plug it back into the fuse block, does it click?
Please let me know...Thanks, Carguyjosh
The relay that I am looking to pull is the aux. relay...
This relay controls power to the rear blower motor. If you can't find this relay, pull the 30amp fuse to the rear blower motor and when you put it back in, listen to see if one of the relays clicks..
Please don't replace anything yet. These steps were actually looking for a bad rear blower motor.
Are you up to the task of taking apart the rear trim panels to gain access to the rear blower motor?
Please let me know....
The most likely cause is the motor. But without testing, I hate to guess...
Sorry for the delay, kids drug me away.....
First, more $ is not even an issue. That is why I haven't sent you an answer for you to accept, we don't yet know what the fix is..... My goal is to get your truck fixed.
I am really leaning towards a failed blower motor. There are not many things in the right rear other than that.
If I can get you to pull apart the trim panels in the right rear, we can get testing the motor..
Please let me know if you want to take this next step...
