A lot has been discussed above and in viewtopic.php?f=28&t=37869 There are a number of things that can prevent 12V getting to the clutch. You never said what year you had, so assuming 03-08. Thank you for responding after all this time! That information really helps. ( but standard caveat, I don't guarantee anything)Ĭlutchwire2.jpg (53.32 KiB) Viewed 1483 times clutchwire.jpg (52.24 KiB) Viewed 1483 times If you read 12V from the connector to ground (11, 12,13,14 volts, somewhere in that range) then the voltage is getting to the clutch, and assuming you are doing this because the clutch doesn't activate, then you probably have a bad clutch. If you read nothing, then there could be a problem with the fuse or relay or something else not allowing the 12V to get to the compressor to activate the clutch. I think the test step you are asking about is to disconnect that wire from the compressor, and with the engine running and the AC turned on, use a multimeter to check the voltage between that cable end connector (only has one pin) and ground, either the engine block or the battery negative terminal. There is a wire that runs to the AC compressor, as shown in the attached images from a 2003 Vibe, should be the same for 03-08's, don't know what year you have. Is that what you used? And how did you do it? Use multimeter or connect the wire to the battery? I only see one wire /connector and that is the one that is connected to the alternator. Mine developed an open in the winding somewhere
Pretty sure Toyota used a different compressor, so although quite often parts from a Matrix or corolla will fit the vibe, this is one case where you need the GM part.Īlso, the clutch is basically a large solenoid, the coil is a sealed unit, don't bother hoping it can be fixed by means other than replacing it. GM part number is 88972204, and the GM list price for the AC clutch kit is about $200, but you can get the part cheaper on line. Granted, there may be other things wrong with the AC system you can't know about until the clutch is working, but I think it is worth the chance that the clutch is the only thing wrong, based on my one data point that the clutch was the only thing wrong with mineĭon't know what a shop would charge for that job, perhaps a couple of hours of not cheap labor.

The AC clutch is a separately replaceable part, so if you take it to a shop, my advice is to not let them talk you into the more expensive job of a full compressor replacement. I had that same sinking feeling only a couple of months ago. Macadoo wrote:Well crud, I have power getting to the clutch.
