My right rear window stopped working. I checked the fuses and #3 a 10 amp fuse is not getting power.Does anyone know what powers that fuse? I only have the basic diagram and it does not show the power source.

as you know there are three ways to open the rear passenger window----door switch----lower control switch and key fob and I am assuming that all three methods dont actuate the window---am i correct???
when you turn the key one position power is turned on to the front and rear SAM which are waiting for CAN instructions to provide voltage depending on the switch method selected----the system is fused from F1 in front SAM and F4 in rear SAM and you know if you have a blown fuse then something might be wrong with the N69\4 rear door control\motor

I pulled the switch on the door and I'm not getting power to the blue wire. The left rear window works and does have power on the blue wire. I haven't tried the key fob because i didn't know I could do that. I'll try it. Thanks Plutoe, for reply.

then it sounds like either one of the power connectors is corroded or the door control module is faulty------the only way to test that is pull the door cover

Do you know how fuse 3 is powered? According to what I've read it should have power all the time. Thanks.

Plutoe

there is no F3 in rear door circuits-----look at your fuse chart

Here's the fuse card that I have.


The 10 amp turns out to be an extra fuse. I do have power on 2 and 3, so, looks like the dcm is at fault.

See attached schematics. Pages 5 and 6 of file 2of2 have the fuses plus the door control modules and window switches.

When you pull the door panel off, expect it to separate into pieces. The black plastic mounts that hold the plastic door fastener clips tend to separate from the panel plus the upper horizontal portion may partially separate from the panel. Have industrial adhesive on-hand plus multiple C-clamps of 2"-3" jaws. I recommend having replacement door panel fastener clips on-hand as those will break.

Photo of inside of door panel. The black plastic mounts (around the periphery) for the fastener clips tend to pull loose from the backing and must be re-glued using industrial adhesive.
