A/C not working on 89' ranger

I recently inherited a 1989 Ford Ranger XLT from my grandpa that recently passed away (old, but only 60K miles or so). The only issue with it (other than needing a new paint job) is that the A/C does not work. I first thought it needed some refrigerant (it was retrofitted for R-134a). I hooked up a gauge to the low pressure side and it's fully charged. I called up my uncle and he thinks it's the A/C clutch, he had me listen for the "click" sound of the clutch engaging which I did not hear. I did check the fuse for it and it's good. Any help would be appreciated.


I should note that I'm relatively new to doing work on vehicles and have no ideal what the A/C clutch looks like(my background is in IT, not fixing cars/truck so I'm a total noob.)

Any AC work I've ever dealt with has always been traced back to the compressor being shot. I wouldn't guarantee that's what it is, but it's a good place to start.

Sadly it appears that your may be right, I've looked online and found out what the compressor looks like. When I turned on the A/C I didn't notice any change with the compressor. How hard is it to replace the compressor (I'd image it would be a pain as my compressor is located near the bottom)?


I did just try to short the leads on the low-pressure switch but was unable to as the connector is stuck on the switch. Can I simply unscrew the switch without refrigerant escaping?

Try to work the connector off from the low pressure switch. Sounds like you have some corrosion in the connector.

I''ll try but it's a little difficult as it's right next to the air intake filter (I might have to take off the the filter cover if i need to.) Can the entire switch simply be removed without much refrigerant escaping? It would make it easier for me to work the connector off of it.

Well I took it to a shop and they got it working again, they said all it needed was refrigerant, I don't know why adding refrigerant didn't work for me, I've successfully did it on my 93 Chrysler Eagle.
