Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hello, did you have power at the low pressure switch when you went to jump it? Is there freon in the system? Have you checked the ac clutch relay?
Yes with a meter. Should have battery voltage at pressure switch, no power, check ac relay in fuse panel under hood, it should be labeled. Should have 2 power sources at relay for it to work, see if you hear it click when installed with key on or engine running. If two power sources, jump across relay switch side, see if compressor comes on. if so, swap out relay and retest
Here is the relay location
Sounds like it is low on freon, look for evidence of oil residue on the ac lines, at the compressor/green dye. If you dont see any signs of a leak under the hood, then it may be a leak at the evaporator core, look at the ac drain at the firewall for dye/
Do you need more help with this concern?
Either it is leaking out faster as you get the compressor running which could be a leak at the compressor front shaft seal or the coil is overheating on the compressor.need to verify if you are loosing power and ground to the compressor coil and if where it is loosing freon. If you keep loosing freon it will not keep the compressor on unless the low pressure switch is jumped all the time
Test the circuit for power and ground to the compressor
check for power and ground o the compressor coil using a voltmeter.
