I have 03 dakota 3.9.ac clutch is not engaging I have power on both leads going into comp.when motor is running 14.4.with ac on,with ac off only black wire has volts..If i run jumper to black whitewire side of compressor coil it comes out on black wire hot.changed coil still same.it was a used coil but before i changed it i ran hot to one side grounded other and magnate worked.now it don't.does that mean coil has shorted out.any help would be apreiciated tks in advance

 

Is the system charged with the correct amount of refrigerant?

 

i think so don't have gauge.has pressure if im getting power to coil shouldn't it kick onI tried to add 134 but it wouldn't take it in I checked hi lo switch it has 3 wires 2 have 5.3 volts one has nothing tried to jump it but it cut motor off

 

im going to get a set of gauges now

 

Jump the pressure switch. If the compressor comes on, it's low on refrigerant.

 

how do u jump pressure switch plug has 3 pins.what is correct hi an lo pressure

 

Pressure switch should have just two. It's on the refrigerant pipes usually close to the drier. Pull it off and put a paper clip across the sockets on the plug.

 

this one has hi and low together i think .its the only switch in ac line its next to high pressure outlet.it screws into line

 

Yeah, just remove the connector. No need to take the switch out of the line. It is a two connector switch on the low pressure line.

 

tried that didn't work put a set of gauges on it blue side read 85 red side read 110
