Where is the AC clutch fuse located?

My AC clutch on my 2006 Ram is not engaging and my Freon level is fine. It worked one day and not the next. It was blowing good cold air and the next day the AC light comes on, but the compressor clutch does not engage. Can't find a fuse marked for it in the big panel under the hood?

Thanks to your help, I was able to find a good .pdf of the wiring for the 06 Dodge. Here are two images related to the question.

Hi @davealex

Looking at the wiring diagram (see image below) from the 2006 Dodge Ram repair manual, it appears that the AC compressor clutch doesn't have a separate fuse.

The same fuse that supplies power to it, supplies power to 4 other components as well. Presumably they're all working OK?

Perhaps check if the wiring from the clutch back to the fuse block (dark blue/yellow wire) and earth connection to the clutch motor is OK and that the clutch motor winding is also OK.

@davealex

The image you posted seems to be from the 2005 model but I'm not sure about that.

Here's the Dodge Ram 2006 Wiring section from the repair manual I used just to check it is the same as what you have

Go to sections 8W-13 -1 (index for IPM p.27 of 520), then section 8W-13-3 & 4 (fuse allocation) 8W-13-29 (AC clutch wiring) 8W-42-1 (entire AC wiring section) The section/page numbers are at the top of each page.

The Dodge Ram 2005 Wiring is more detailed and looks like what you posted re the IPM layout.

I can make out from the diagram that there must be a Relay in the Power Module that is associated with the clutch. Likely is fed with signals from the Pressure sensor(s) etc. So if you also have a picture of the IPM components and their names that would be so helpful! Thanks again.

I have posted images of the diagrams I was able to find. If anyone needs more info, I now have the complete wiring in a .pdf for 2006 Dodge Ram(s)
