A/C clutch

I was wondering, my a/c doesn't work. I've had the system checked and I was told that it is full charged but I might need a new compressor. I was thinking that the clutch field is broken but I have no really good ideas on how to remove it. I have a replacement. I'm figuring there has to be special tools involved, but how to do it and where to get them? Anyone have done this before and have some advice for me please...Thanks

Re: A/C clutch

before you go too crazy with this, try the following:

1) disconnect the clutch wire at the connector.

2) using a multimeter set to Ohms (or resistance...), measure the resistance from the AC pump case to the wire you just disconnected.

You should get a very low resistance reading -- less than tem ohms. If you do, then the clutch is good and something else is wrong. Also try the same measurement using the frame or other exposed metal part to make sure that the AC pump has a path to ground (it should...)

If you don't have a meter, find a suitable heavy 3-4 foot wire (at least as big as the black wire going to the clutch) and connect it to the DISCONNECTED wire that goes TO the AC clutch

(NOT to the firewall fer cryin' out loud!).

Touch the other end to the positive terminal of your battery. If the clutch "Clicks", then the clutch is good and something else is wrong in the A/C system.

Naturally, the ohmmeter method is the least scary, but the "put the dc to the clutch method" works as I have tried it!

I disavow any knowledge of this post if you do something stupid like connecting the positive side of the battery to the clutch wire going to the firewall and frying your electrical system.

Hope this helps...
