I last used my A/C on April 2nd and worked well. On the 10th I tried to turn it on again and the A/C didn't cool. I have checked all fuses and the relay in the fuse box. The clutch sounds like it is trying to engage but the compressor will not spin or lock in. Am I missing something obvious?
Help it is hot down here!

Something that happened with my wife's Impala..and yeah, I know, it isn't a truck but......
Had the same problem. The ac worked fine one day...the next it crapped out. Also noticed the temp gage went at the same time.; Dealer said it was the module...to the tune of $400. It worked great for a week...then the same problem. Dead ac and temp gage. Dealer did some more work and said "Thermostat...$120 please."
I pointed out to the dealer that it was probably the thermostat all along and not his $400 module...so he owed me $280 for the difference. He decided to replace the thermostat on his own.
The ac has worked fine for months now....you might want to check your thermostat. Could be a cheaper fix.

If the refrigerant in the cooling system is low the compressor clutch will not engage.
I see you "checked" the relays. I fixed my once by tapping each relay in the box under the hood with my finger. When the stuck one picked up it was very audible.
