RW> My next door neighbor just parked his 08 Chevy duramax and bought a daily   
   RW> driver, an 02 2500HD. It's AC wasn't working, so his dad or FIL came over   
   RW> and helped him replace and clean the system. The compressor had exploded   
   RW> internally and filled the system with junk. Not a hard job, just hard to   
   RW> get to. They removed inner fenders and wheels to get to the compressor.   
      
   Sometimes it is difficult to get all the junk out of the A/C system if the   
   failure was compressor related.  Sometimes they fail and don't throw junk in   
   the system.     
      
   Most of the cases I have seen with A/C systems are leak related.  Many sleezy   
   side of the road used car salesmen would just re-charge the system so it   
   appears to work.  Then 6-8 months later, it is not working again.     
      
   RW> and blew the utiliy company's 100 amp fuse. The welders found a   
   RW> replacement fuse and blew it again when they tripped the breaker. This   
   RW> happened while we were in AZ on a well needed vacation. When I got back   
   RW> to the shop, 4 days later, I removed the wiring from the breaker box and   
   RW> found that the line was melted together and probably touching the   
   RW> conduit. I pulled some new wires through the conduit and all was well   
   RW> again, but I wouldn't allow the welders to use that welder on any heavy   
   RW> jobs again.   
      
   That is a ton of amps on that fuse!  Not something I would want to stand next   
   to if it shorted out.  :)
