auto cab climate control problem

Recommended Posts

The auto temperature feature on my '02 2366 has become erratic.  There are no error codes appearing, but the A/C sometimes will not cool, no matter where the temp knob is set.  Then all of a sudden it will start and run for awhile and then quit again.  Has anyone had a similar problem?  Thanks for any input.

Have had a couple things happen that I can remember.

#1. When it does act up, see if you have power at your AC clutch. If you do, the gap for the AC clutch is too great or else the coil for the clutch is getting weak. Have seen them "come and go" like that.

#2. Either of the in-cab temperature sensors can cause this. They can fail to the point that the ATC thinks that the cab temp is where it should be, but not far enough out of range to cause a fault code for the sensors themselves. One is stuck in the AC evaporator coil, while the other one is behind the seat under the cab recirculation filter. Good luck!!
