Both rear windows in my dad's 2005 Deville stopped working. I checked power at the rear fuse block and it was good, but no power at the motors. Turned out, the 14g orange wire was broken at the rear left pass-thru grommet. And the 14g black wire was broken at the right rear pass-thru grommet. Went to harbor freight and got some bud shrink splices and got the windows fixed under $2.

Note: All 4 windows sharing a 30A fuse. If your front windows work and the rear isn't. Before replacing anything, remove the grommet at the B-pillar and inspect the wires. When you open the door, it palaces a lot of stress on the wires, overtime they will break.

Glad you realized what it was. This forum is well aware of this problem and I am surprised nobody responded with the fix before you did. BTW it happened to me last year. lol

Where is the B pillar? I'm having a problem with my rear doors.

It's the pillar between the front and rear door.

Yeah a classic case of the wire loom splitting and making crap not work in the rear doors. It's one of the first issues I had with my deville too.

Thank you for this info. I bought a 05 Deville for a work car, rolled the rear windows down and they didn’t go back up I jumped the window motor to get them back up
