My 2000 Jetta’s air conditioning will suddenly start blowing just cool air; a remarkable change from the cold air normally produced. After a few minutes, it’s apt to return blowing cold air.
Is this a sign of a compressor close to failing? If not, what pray tell?
When it’s just blowing cool, are you hearing any squeal? If possible when it starts blowing cool check to see if the compressure is turning. If not it just may be a pressure switch going bad. I realy don’t think your compressure going bad. Usualy they make noise when they go out.
Low refridgerant symptons.Get pressures checked.Any AC repair history?
