Looking to get some advice on this issue. I replaced my rear crew cab power window motor last year, and also ran through the known wiring issues with the crew cab trucks.
Recently it quit working again totally. Today I ran through all of the wiring and I am getting 12v everywhere that I need it, so the door switch is working. I pulled the power window motor off and applied 12v to either of the terminals(up or down direction) and it doesn't work. Any advice on what I can checkout on the inside of the unit itself for function? ETA: Just popped the motor open and the gear side spins freely and looks good. The motor portion is locked up solid and there is corrosion present on that side. |

I'd suspect it's getting wet; they should last longer than that. Either that, or bad ground; but if you wired it directly to a 12V source, the motor itself may be toast again.
Like any electric motor, it'll have an armature, field, and contact brushes. If it is moisture contaminated, you'd see blue-ish corrosion internally. Probably cheaper/easier to replace than to repair, but I would have a look at the window seals for dry rot, ripped and/or torn neoprene, etc. |

My seals are old but not leaking and the plastic door cover was sealed tight. Appreciate the information bud. |

Hey guys,
Just an update. I got the old(>1yr old) one warrantied out. I installed that one and tested it and I also was getting nothing. So I went ahead and used my multimeter and I am getting 11..9-12 at the door. I also took that same motor and attempted to bench test it and got nothing. I thought maybe my batteries in my pickup were dead from listening to the radio for a couple days without starting it. However, all 3 of my other windows work as well as my power locks so that idea is out. So I figure I just got a sucky reman. I got one more so I will see what happens now. |
