Check ground at Powertrain control module. All of your problems tie back to G200, G201, and G300. Take a look at fuse J and Fuse 2 and or 5. Attached is an electrical diagram. 1st 4 pages are AC and last 2 are mirrors.

checked all of my fuses, none of them are blown, just dont have the lights in the a/c switches and the compressor clutch wont kick in, i got under the truck, and spun the pulley and clutch, there not frozen... :thud:

 

[Ops]

sounds like a freon leak to me. Take it back..

Ops

i did i know the compressor wouldnt kick on because of the coolant, but that wouldnt affect the lights on the a/c panel, and i double checked for leaks and couldnt find any... :thud:
