a/c out on 06 2500

[mrtowman4u]

Hey fellas, I need some help on an 06 2500. The truck belongs to a friend of mine an he called me an said his ac went out! I told him i would try an help out on this! Well I had a friend that works from dodge check it out, he said it was a bad clutch on the ac compressor. I order new compressor for the truck, an today I was driving the truck down the road with the old components still on, an the ac started working fine! Turned the truck off now ac is dead again:banghead::banghead::banghead::banghead: Can anyone tell me where I need to look at on this thing?:pray: The truck is an 06 2500 ctd with 5.9 cr

sounds like the clutch is working intermitantly. bad connection? bad clutch? thats about the imit of my knowledge on ac.

[mrtowman4u]

That's the weird thing! You can turn the clutch freely!

[dripley]

mine spins with the truck off. i believe they all should spin when the clutch is not engaged. you might have a loose or damaged wire in the connecter or the harnes causing it to come on and off.

:banghead:Ok I've done some checking, when you have truck running and a light tester at the wire on the clutch, the light tester will light up 3 or 4 times and compressor tries to kick in. So I made a jumper wire from hot side on battery and ran to the wire for clutch, compressor kicks in and runs and cools good! So where do I go from there?

Check the AC compressor relay to see if its wore out. The compressor wiring is fairly simple. +12V -> Fuse -> Relay -> AC Clutch Relay signal is from the PCM which has the hi limit switch and the low limit switch. So check the relay socket for signal from the PCM. (85 & 86) should have power and a ground present when the A/C is on.

[mrtowman4u]

Mike, aren't the relays built into the intergrated power module?

sounds like you need a wiring diagram and start following the wires until you find the bad connection or wire then repair it and you should be good to go. i dont know if mopar has an 06 diagram in the down load section. i dont think it would be hard to come by on the internet. Electrical is a weak spot for me and i am not good on procedure. i just looked at mine and there is only couple of wires to trace, but wiring diagram is going to help alot.

[mrtowman4u]

I have access to dodges wiring diagrams! Think I found the problem will post soon as I know for sure!

[mrtowman4u]

Ok I now have the ac fixed!!! The clutch was bad on the compressor! Replaced with new now truck is blowing 40* at idle now!

[dripley]

happy you got her fixed.

[Mopar1973Man]

What did the clutch cost ya?

[mrtowman4u]

Couldn't find just the clutch, found a new now compressor, drier, o-rings, an oil for $300 on eBay!

[Mopar1973Man]
