a/c

[Exekiel69]

Anyone have a wiring diagram for the a/c on a 93? I checked the fuse and it is good but I still don't get power to any of the two wires that go to the a/c that is as far as I got for now.

Thank You.

Got power to the pressure switch over by the fan box?

have any pressure in the system? AC wont turn on if its not filled at all...

A/C system is charged but that isn't what I'm trying to figure here or is the pressure what will turn the pressure switch ON and send power to the pump? I don't remember touching anything on the a/c wiring but i do not get any power to either of the two wires that connect to the a/c pump (blk/ylw - blk). Are this wires on the pressure switch connected in any way with the pump?


Thank You.

Yes, jump the pressure switch with a paper clip, then your pump should come on.

right it needs pressure to turn on the system. prevents damage from occuring to the pump if there is no refrigerant in the system.

like when you recharge a dead system. the pump will start clicking on and off and will do faster until it is up to pressure and should stay on all the time the AC is switched on.

Thank You guys it didn't have enough pressure at the switch. This system is part ford part dodge so I had to get enough refrigerant to get the switch to turn ON. Pump turns ok wen I jump the wires on the connector, I got about two cans in it so far so I'll go get Me another one and see if that raises the pressure enough for the switch. The gauge still shows it needs more to fill.
