jeep a/c noise, quick temporary fix.

Hi, I have a 94 4ltr. Auto, the a/c clutch has failed (making grinding noises too often) I can't take the car off road till after Xmas... If I disconnect the electrics from the pump, would it stop the grinding and still be safe?
Thanks in advance,

Bez

If you pull the A/C relay in the fuse box, the clutch won't try to engage the compressor. If it's making noise without it trying to engage (IE the hvac system is off) ... then this wont' work.

Millermagic,
Thanks for that, will that not bypass the radiator fan as well?

You can disconnect the connector at the Ac unit. If you can't reach that, then pull the connector at the pressure switch (which is usually easier anyway). It is on the right side of American Jeeps, however, your set up may be different. As stated above, if the grinding is constant, regardless of whether the clutch is engaged or not, then you have a bad bearing in the compressor. You will need to stop driving the rig till you can get it fixed.

Thanks for that, I'll use that disconnection if the relay removal fails... But, I must say everything at the moment seems to be doing, or not doing as planned.

Thanks again.
