I have a 95 Ranger and I’m trying to get a/c working. I’ve checked the system and have Freon. My problem is where the WOT A/C relay goes I have nothing to plug a relay into. It’s just a blank space with holes but no receiver end for the relay. (if that makes any sense) I checked the compressor but it’s not engaging but it is loose and not locked up. Can anyone help me out here? I can send pics if needed. Thanks in advance!!

 

Then its not factory AC

You don't NEED the WOT relay, it always passed voltage to the compressor clutch unless it was Activated by the computer

When you select AC on the cab's panel a purple wire sends 12v to the first Pressure switch in the engine bay then a red/yellow wire from that switch to the next pressure switch then a Dark green/orange wire from this switch to the WOT relay OR........to the compressor clutch

Fuse 18 12v----Cab AC switch-----------------pressure switch-----------------pressure switch------WOT----(black/yellow wire)--------compressor clutch

 

so should I check the compressor? I just need to get the clutch to engage I’m assuming?

 

Yes, the clutch needs 12v and a ground

Factory AC Clutch wiring had a Black ground wire and a black/yellow stripe 12v wire

You need to get 12v to that wire to start compressor

It(the 12volts) went thru the 2 pressure switches so system wouldn't EXPLODED, from high pressure, and wouldn't GRIND UP compressor, from low pressure

So its a pretty simple setup electrically
