[V8] V8 Rear Pwr Windows

[Professor GT gmail]

Guys,

I recently repaired both inop rear windows in my V8. They would both load the ele system when I tried to operate them from either the master or the door switches (dimming dome light) so this was a good indication that the issue was in the motors/regulators.

The good news is that the window cartridge removes very easily (glass, frame, regulator and all) - this is a real nice design.

The better news is that the motors and regulators are completely rebuildable! No rivits to drill, and nothing to chisel apart. Just unbolt everything and recondition the motor, clean, lube and reassemble, and away you go.

My motors were seized up due to water intrusion, and the inadequate drains. I removed the rubber nipple drains and the plug opposite the drain so that any moisture can easily exit the motor, and I quite liberally lubed things up in both the motors and the regulators. Note that the motor/armature assembly cannot be slid out of the regulator until the driven gear of the regulator is removed. That's about the only tricky part about it, if you could consider any part of this repair even remotely challenging at all.

I was thrilled that the design allowed complete disassembly and rebuilding of the motors. This turned it into a labor only job that costs just some time, some crocus cloth to polish the commutators, some cleaning solvent and some grease. All in all, a couple of hours work and some elbow grease and they were good as new!

Now the rear windows go up and down once again, so my kids are happy, and will keep them exercised so they don't seize up again. (I'm sure the copious amounts of lubrication will help there too!)

Now the only remaining issue is that the R/F window will not operate from the R/F door, and the rear cig lighter is inop. I've ruled out the switches, and this leaves it to a wiring issue if either high resistance or an open n the hot side of the circuit - work for another day of V8 TLC!

Thanks,
