Ive search and cant find a schematic for an 03 MCS . I found a post that said to ck the clutch coil for an open thru the relay but im not sure thats accurate bec everything checks out ok . I see the coils resistance so its not open but still no compressor engagement . Fuse ,relay ,pressure (80psi low side ac off) all seems ok . It was working one day and an hour later dead .

I tried to access the compressor coil wire directly but as we all know thats almost impossible

A schematic would help greatly

 

You did check out the FAQ area? Item # 0015 in the below thread.

yes and I searched and found just about every other schematic but not the ac circuit . Are you sure its in there somewhere ?

 

I used an ohm meter to test for an open thru the relay socket for pins 30 and 87 and I get aorund 5k ohms so does that indicate that the coil is ok ???

 

Assuming you measured correctly of the AC solenoid 5k ohm is infinity in the scheme of AC things. I.E. open. Next step, go straight to the solenoid (clutch) and measure there.

 

Too funny ... I found it under K19 relay ,ac compressor . SO it looks like I have a mystery . The resistance of the coil measure at the relay is around 5k which is correct however when I energize the coil by shorting 30 and 87 the clutch wont engage .. Any ides ?

 

I tried to access the coil directly but as you know its almost impossible . I tried thru the wheel well and also from underneath .
5k is no good ? . I did a search and found that to be about right or so I thought ... also dont they usually short

 

So sorry and thank you .It turns out it should 5 ohms not 5 k . Gonna order a new clutch from ebay
