Hi All,
My wife has a 500X we purchased a few months back on a private sale, A/c didn't appear working so negotiated a bit from the asking price to get it re-gassed!!! The wife wasn't to bothered at the time but now the summer has hit she would like the A/C sorting.
I've had a look at it and I think the Compressor is NFG but I would like to run some thoughts before I take it in to the garage.
The climate control functions seem to work as should, If I set it to MAX a/c the cabin fan run full blowers move to centre and have no flashing light on the A/c button just a solid amber light. the compressor does not cut in.
With the engine off I can rotate the center of the compressor.
I put a set of Gauges on the low side and have about 120psi, the gauge doesn't move when the engine is running, I wondered if this was a little high but given the ambient temp has been 25 degrees C I though it may be right??
I've checked Fuse F9 in the fuse panel under the bonnet, that is okay.
I found the 12v control relay for the compressor, removed it and tested, it appeared to be ok but found a bosch one online so replaced it. Still no compressor run.
I removed the relay and used a jumper to short the switch pins and the compressor clutch clicked.
After this I ran the engine, shorted the switch pins at the relay/fuse board and the compressor engaged and centre section started to spin, however the gauge needle stayed around 120 psi and didn't move?? I checked the cabin and the vents were still blowing warm air.
could a faulty pressure switch still stop the A/c even if I've effectively bypassed the control system?
the only other thing I have noticed is the outside temp sensor is not working, all we have is a -- on the center screen.
Sorry for the long post and I appreciate any comments.
