| | A/C problems on 2000 mustang
a few things about my A/C is a while back at times when my A/C would be on, I would sometimes hear a loud scratching noise that would only last a few seconds and i wouldn't hear it again for awhile.Also, I did notice that my compressor clutch would stay on and never disengage, as i was refilling my freon. Maybe this caused me to get bad reading on the pressure so I may have filled it to much. Sometime later I went to turn on my A/C and I heard that scratching noise again and my vents started smoking, I believe that it was freon coming through my vents but I'm not sure. Since then I have not touched my A/C at all because I don't want to make the problem worse.
Any help would be greatly appreciated. Thank you very much.
