When I picked it up, the a/c guy stated that he thought it may have been
evacuated, but to try it anyway. No cool and then smoking fuse. I'm
thinking that just having it empty may have caused the fuse to blow...so I
am gonna find a couple of fuses and have him fill it then install the fuses
and try again. Does anyone know if having an empty compressor and then
turning on the a/c would cause the fuse to blow? Thanks again.
