New compressor time, the clutch is not available separate.

 

I just fixed my AC. It was blowing the fuse when the clutch wire was plugged into the harness. When I disconnected the clutch wire from the harness it would not blow a fuse.

Under the plastic casing on the wire coming out of the clutch there is a diode. I cut away all the protective covering on the clutch wire and found the diode was broken in half.

Went to Radio Shack and bought Rectifier Diodes (25-Pack) Model: 276-1653. I used the 1N4007 diode that was in package and attached to clutch wire with the stripe on the diode closest to compressor side.

I thought I would need a new compressor or a clutch too but I was lucky that it was only the diode that was bad. Only cost $2.99 and about 30 minutes of time. Now the compressor kicks on and keeps me nice and cold.

It is worth checking before replacing the compressor or clutch if you are blowing the AC fuse.

 

Hi rgviewer I know this is an old thread , But I have the same problem.. My unit is a 2004 5.7 Hemi , I can't get the compressor bolt out of the end . I checked the plug wires and there's a dead short in my compressor somewhere . Please tell me how to fix it.. Thanks..

 

Check wires again. Should not be any wires going to compressor. Wires should go to clutch on the front. Obtianing a clutch alone may be difficult, but if it is shorted, there is no way to fix it other than replace.

 

Im not sure how to fix any short in the clutch, All I did was cut away the protective cover off the wires going to the clutch, found a bad inline diode and replaced the diode.

I really don't know much about auto A/C but a friend of mine took his Ford clutch apart and left out one of the shims and now his A/C works great again.

Wish I could be more help, but check for a bad inline diode on the wire set going to clutch or tear it apart and put it back together. Its already broken so what do you got to loose.

Either way Good Luck

 

Maybe this will help some. https://dodgeforum.com/forum/2nd-gen...tructions.html and this http://autorepair.about.com/library/faqs/bl249i.htm

 

Dude, I just made a profile on this site just to thank you for this advice. I literally did exactly what you said here, and the diode wasn't broken, but it was shorted. The fuse to the A/C clutch kept blowing on my 5.9L 1999 Ram 1500 every time I replaced it, and the compressor wouldn't turn. Cut otu the diode and threw in a new one, $1.49 from Radio Shack (1N4004), positive side facing the white striped wire. Suddenly compressor would turn, A/C is cold. Yes, this diode is DEFINITELY worth checking. Thanks guys!

[By the way, I often read these boards, and almost always find solutions to fix my truck on the cheap. It's got 225,000 miles on it, so they come up somewhat regularly. Thanks for all the great advice!]

This is my first time posting. Just wanted to say thanks for this info. I just fixed my 2000 ram 2500's a/c by checking and replacing this diode. Remove insulation from the plug side of wire and about 3-4 inches down you should find it. I used a 1N4007 diode also, anyone with a little auto know how should be able to do this easy fix. I spent 50 cent and about 30 minutes and my a/c works great.

 

Thats great to hear. I have used this site for years and have received great advice from members on this site which has saved me hundreds of dollars by fixing my truck myself. It's nice to know that I myself was able to finally help someone else out. People are what make this board.

 

I just fixed mine by replacing the Diode in the clutch wire. Thanks for the fix it worked great.
