Changing A/C Clutch

i think the a/c clutch on my 89 F150 is toast. I'm getting power to the compressor, but the clutch won't kick. I tried bypassing the low pressure switch as well.
How hard is it to change the clutch? Or should I just swap out the whole compressor? it still has R12 in it. I'm just looking for a cheap fix for now. I even thought of tapping a few screws into the holes in the clutch and lock the clutch up, but I don't want to ruin anything.

did you check the ground? test resistance of the clutch coil? use jumper wires to feed both positive and ground to the coil (engine off, of course)? do at least those tests before condemning it

It requires a puller, but the clutches aren't too bad to change, but i've only ever changed them on a bench.

Is the a/c comp at leat up near the top of the motor?

I actually wired the compressor directly from the battery and no difference. I'll double-check the ground.
The compressor is right on top of the motor, easy access.

If the compressor is original, I would go with a whole unit. The clutches can be a PITA to change, especially a 21 year old one. Time or money, take your pick.

Not sure on the fords, but I have done the one in my jeep. (piece of cake) Just go rent the clutch removal tool and pick up a new clutch.

On an old car I had, my A/C clutch started making a bunch of noise/ engaging hard. As a last ditch effort before routing the belt as if A/C wasnt installed, I hosed the clutch down with WD-40. I stuck the red straw in between the spring, and emptied a 1/4 can into it.

Worked flawlessly after that.


Probably not the same issue, but just a thought.

That compressor does NOT require a puller. All you need are snap ring pliers. Really easy to change, even on old vehicles. I've changed several.
