I have a intermittent A/C problem with my F-150 STX. In the mornings and sometimes in stop and go traffic, the compressor will cycle off for as long as three minutes. I have had the condensing coil, Hi-pressure washed by a dealership which said "This is a common problem with A/C units." [THIS DID NOT REMEDY THE PROBLEM] I had a service writer @ Dave Moore Ford (Dianne Chestnutt) in Beeville,TX tell my son, "Well because of the hot weather that's just the way A/C units perform now day's."{BULLSH*T]. I had the service manager @ the same Ford Dealership ( Robert Rodgers) tell me to " Take your vehicle back to the DAMN Dealership were you bought it and let them work on it." I inturn called Ford Customer Relations, which replied "We do not intervene in Dealership complaints."..............{THIS IS NORM FOR THIS DAY AND TIME}. Well, back to the tech problem........ The technicians have yet to find the problem...... The Hi-Low Pressure switch seems tp be working properly. The Freon Volume seems to be with in limits. The Relays seem to be cycling properly. I also asked if maybe there is a recall or service bulletine, maybe a A/C system overcharge from the Factory........ "Does anyone else have any ideas?[:@]"

 

[sm=welcomesign.gif]When the a/c cycles off for 3 minutes does it blow warm air?

 

Yes, We live in south Tevas where the humidity is very high. You, can tell to the second, when the compressor turns-off.

 

My guess is it is a electrical problem.
