AC WOES (WTF!!!)

[jsbihn]

Ok, so if there is one thing on my truck that pisses me off beyond belief is this damn AC system. I have been battling this thing since I bought it.

Here is the latest.
Ok, so I buy a new AC compressor and condenser and have them installed. Ok it works for a week and then its blowing hot air again.... turns out a bad seal. So They put a new seal in and put the charge the unit... ahhhh 45 degrees again..... two weeks later its on the crapper. Ok, so now they want to replace the condenser and the connecting pipe (they say the seal is good but they think it is all out of round). I asked them if that was it and they said well they didnt check the whole system. I was shocked. I told them to check for any leaks or problems. Suddenly this seems new to them. Ugh. Ok so the system supposedly is fine. Ahhhh nice 45 degree ac AGAIN!!!

Today I was sitting in front of the kwik-e mart and all of a sudden I could feel it suddenly change temp. I look at my vent thermometer and it shows 60 and it is climbing. My AC without sound or warning or anything is now in the crapper AGAIN!!! I cant tell if the AC is engaging (cant hear the clutch, and it was so noisy driving and so damn hot and humid). Everything is working, just no cold air. And like I said it just suddenly stopped.
Is there anything I can check or hot wire to see what is going on with this system prior to me bringing it in tomorrow morning.
Your help is appreciated
