Re: 2005 Grand Cherokee heater fan control failure
 
Bill,
I think you're talking about the aux fan that lives out by the grille and
radiator, but I thought the OP was complaining of the fan that lives inside
the cabin.

Re: 2005 Grand Cherokee heater fan control failure
 
Hi Don,
Air-conditioning compressor normally cycles off and on. There are both a
high pressure and low pressure safety switches that are designed to save the
pump if one happens. You may be low on Refrigerant R134a, that may be
checked with a gauge: http://www.----------.com/temp/r12gauge.jpg The low
side should read a little higher than R12. This real should be done by a
licensed tech.
