I replaced the evaporator 2 years ago but ever since my A/C will come on and then shut down. While it is running it is very cold (around 42 degrees) btu after a few minutes or a few miles it shuts down. I can always tell it is ready to shut down because it gives off a funky musty odor that I know means my A/C just crapped out. SOmetimes it will restart after I shut it down but in general it works 1% of the time and is not working 99% of the time.
Question.... Is there a Pressure sensor on the compressor or seperate from the compressor that is sensing a build up in pressure or a loss of pressure in the system?? SHould I just give up and go for a new compressor?
