Ford A/C problem

thistlesmith · 06-07-2016, 07:19 PM

I have a 2013 Itasca Suncruiser on a Ford F53 chassis. The A/C quit on our last trip. Fan works. Checked the 3 fuses, 1 relay, and 1 diode that service the compressor clutch and all seem to be in working order. The clutch does not appear to be engaging. Haven't checked refrigerant but think the clutch should be working first. Where do I go next?

Check the refrigerant. The clutch will not engage with low pressures.

That protects the compressor from running starved.

What changed? What did you fix? Need to know the rest of the story . . .

Also, during that timeframe, Ford had a recall on the dash A/C. I don't remember what it fixed, but you might want to ensure that you have it completed.

Bought a recharge kit from Advance Auto, hooked it up, and in the process of charging the clutch engaged. However, the next day the clutch did not engage again so I suspect a more serious leak.

The Chassis AC was actually installed by Winnebago, it should be a TEMPCON system. I believe the only part that FORD owns is the compressor.
Be very very cafefull on the EVANS TEMPCON system, The system on requires about 2.13 lbs of Freon, which according to them you should fill from empty.
Check out the EVANS TEMPCON web sight for info on trouble shooting your AC. Evans Tempcon, Inc
