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.  :)
