I recharged the ac system on a 2000 ford mustang. The ac clutch is not engaging. I changed the high pressure switch and low pressure switch. When I have a little freon in the system, it works fine but blow warm air. I put more freon in it and the clutch doesn't work anymore. I check for voltage at the low pressure switch and there is 13.73 volts. I checked the 4 pins on the high pressure switch and one set was have positive and negative with the ac off and when the ac was on. There were 2 sets of power. I checked all fuses and relays. When i unplug the high pressure switch and plug ot back ot, the clutch engages for a few seconds and turns off. The same thing happens when i do it to the low pressure switch. Checked voltage at condensor. I'm lost now.
I used the jumper and the clutch engages for a few seconds and turns off again.
f it was a ccm, why would the clutch and compressor work perfect with a little freon? Also how to I bypass the 4 wire high pressure switch? Where is ccm located?
What reservoir is it behind?
I don't have a ccm behind the reservoir
So the ccm is located under the fender on the passage side. I just tried to jump those wires you told me and the clutch still didn't engage.
I have to remove the fender tomorrow
There is no dark brown wire with the yellow line on the high pressure switch
When I jump those wires, nothing happens
