I'm hoping somebody can help me with this one. Last night while driving my wife's Explorer the AC stopped blowing cold air abruptly. There was no sound, no squealing or scraping or anything. About 20 seconds later, with the AC still on, I smelled some burning rubber/electrical smell. I turned off the AC and the smell stopped. The serpentine belt is just fine and doesn't make any sounds at all.
The radiator fan and AC Condenser fan are both electric and mounted side by side. If I spin the radiator cooling fan it will do a full turn pretty easily but the AC Condenser fan wont do 1/4 turn with the same pressure. Both make some noise but the AC Condenser fan squeals pretty loudly.
Am I right that with an electric cooling fan there should be some resistance from the brushes but it should still spin relatively easily?
Then it would be likely that the squealing sound is bad bearings in the AC Condenser fan and that would likely be the burning smell?
If the Condenser fan stops working the system overheats and stops cooling?
And assuming this is all true could a minute at most of driving do anything bad to the compressor?
Hoping I'm right as the dual fan assembly is about $150 vs $1500 or more if the compressor died.
Thanks for any and all advice!
