A/C compressor cycle switch

[Rockcrusher]

A/C quit working and so started trouble shooting. Was afraid the compressor clutch may be bad as the clutch wouldn't engage. Checked its continuity and it was good. Temp power to it and worked OK. Next step was to check low pressure switch(usually the culprit) but it checked OK too. Horrible location to get to next to the H valve. More checking of the "electronic compressor cycle switch" showed no ground for the clutch circuit. Checked all the parts houses; no one carries it. Surprised Dodge dealer had it, $58. Installed same and A/C works fine.

Just wanted to let you guys know if you have to change this or the low pressure switch, its a nightmare to get to. Barely room for small hands but my big old meat hooks came out torn and bloody. :--)

A/C

Glad you found your problem. I had an A/C outage when I bought mine; the lead wire's to the compressor rubbed out on metal frame just after the plastic disconnect. May want to check your wire condition as it may save you a problem down the road.
