dannel Posted July 12, 2010 Report Share Posted July 12, 2010 the air works perfectly at startup. After several minutes (as it heats up ?) it stops. after 5 minutes ( when it cools down ?) it starts again. Seems like a resistor over heating, splitting , then cooling and flowing again. There does not appear to be any a/c codes current. I recall a ceramic resistor in an old oldsmobile I had that would stop the air from working, is there such a thing on my 97 deville ?

JohnnyG Posted July 12, 2010 Report Share Posted July 12, 2010 When you say "it stops", do you mean the fan quits blowing? Or, does the fan continue to blow air, but it's not cold? Never underestimate the amount of a persons greed. Link to comment Share on other sites More sharing options...
dannel Posted July 12, 2010 Author Report Share Posted July 12, 2010 fan keeps blowing, but blows hot, if you turn the car off...and restart after a few minutes, blows cold again and starts the cycle once more Link to comment Share on other sites More sharing options...
KHE Posted July 12, 2010 Report Share Posted July 12, 2010 When it stops cooling, look at the compressor clutch - is it engaged? If it is engaged, you will see the hub face turning. The problem could be too wide of an air gap on the clutch - easily fixed but it takes a hub installer tool and feeler gages to do the job.
