Piston Slap: Hot Air on Frozen A/C Evaporators?
TTAC Commentator Stefan writes:

Sajeev, my old triple-black 1997 Town Car has developed some air conditioning problems and my trusted independent shop seems unable to duplicate it nor to understand it. Maybe you and the B/B can help?

The a/c always works when starting up the car but will abruptly cut out after a while, almost as if the clutch disengaged. This happens even when the system is fully charged. I was told by the technician to keep the fan blowing full speed but this merely delays the inevitable cutting out. There does not seem to be a refrigerant leak. Not being an air conditioning expert by any means, I am at a loss on how to proceed.

The car has only 170,000 miles on the meter and should be good for another 100,000. Not wanting to spend big bucks on replacing the entire system, where to start?

  • AZFelix This article takes me back to racing electric slot cars with friends on tracks laid out in the basement. Periodically your car would stop due to lost connections or from flying off the track and you would have to dash over to it and set it right. In the mean time your competitor would race ahead until faced with a similar problem. It seemed like you were struggling harder to keep from losing than trying to win.
