AC went out, car started to smell, then smoke
I was curious if anybody knows what is going on. It seems like the entire car is falling apart. 2003Z with 92k.
After a couple hours of driving in hot humid traffic, my ac went out. It kept blowing air, just not cool air. Then about 2 minutes later, I started to smell something burn. I really can't describe the smell, maybe a burning rubber or plastic smell. I got off the road as quickly as possible, and shut the car off. Fortunatly I was right next to where I was going, my grandparents house. It was smoking pretty bad when I popped the hood, and it looked like it was coming from around the AC compressor. Oil temps and Coolant temps were fine.
I left the car at my grandparents and don't have time to mess with it right now since my grandpa just passed last night. I have not pulled any codes.
Any ideas?

Rebel, and Lucky, thanks for the help.
Tonight, we let the heavy traffic die down and let the car cool off for 5 hours. I left the AC off, and I drove the car home 5 miles on the loop in Houston. No stop and go, just a strait 70mph drive. When I got the car home, there was a slight burning smell when I popped the hood, but no smoke.
Would this have anything to do with my DMH cutouts locking up yesterday?(had to do 100mph+ for a couple hundred miles from San Antonio to Houston for his last few hours). I've got a big cam in my car. Any chance that the wiring of the cutouts and them locking up(possibly shorting or burning out) had anything to do with this?
Also, is the belt conected to the crank pulley? If I cut it, would it have a chance of throwing anything out of balance internally on the motor? I can live with no AC for now, but just don't want to drive my work van this week for the family meetings/funeral/ etc.
Thanks again,
Mark

a/c belt is separate... remove the belt...will not affect anything besides the a/c..and it does not work anyway....
sounds like a bad compressor as you were told about above....
hope everything gets better...

Thanks Tommie. I'll cut it off the car tomorrow since I'm sure it needs to be replaced a long with the compressor. Found a new AC delco one in pearland for 100 bucks.
Also, are all ls1/ls6 compressors the same? And are they different on Fbodys than vettes?
