2007 PT Cruiser AC Warm & Rough Idle when Idling

Asked by Oct 04, 2017 at 09:10 PM about the 2007 Chrysler PT Cruiser Base

Question type: Maintenance & Repair

My PT started to run hot a few months ago.  Since I have had to change out
the Thermostats several times in the past, it was replaced, radiator cap and
the coolant flushed and replaced.  A few weeks later while in a drive thru, the
car really over heated, turned off AC.  Cooled off while driving.  Had the
cooling fan replaced.  Then when stopped in traffic, the AC would start
blowing warm air and the car would start to idle rough and sometimes stall.  I
turn off the AC and it runs just fine.  Had the Low Pressure AC Sensor
replaced.  Problem still Continues.   Had the Low and High fan relays
replaced. Problem still exists.  What else could be wrong?  No codes have
ever shown up on dash.  This is becoming a very expensive issue.  I was
told by a ASC tech that the low fan should turn on any time the AC is turned
on.  It does turn on, but then turns off within 5 seconds.
