Guys,

Has anyone ever replaced the Brushes in the Electric Window Motors for a GQ TROL?
If so, where did you get the brushes ? Auto Electrician or NISSAN ?

Regards,
Tom

those motors are a PITA.. I replaced 3-4 of them over the years.. never replaced brushes though. I'd highly doubt Nissan would sell them, they probably sell the whole door.

Speak with an autospark first.

I'm looking into replacing at least one of the window motors on my GQ since the windings are shot (blackened in at least 1/2 of it). I tried just cleaning up the brushes but it didn't make an difference. It did get me thinking about replacement brushes though and I think the best option (if you can't track down originals) would be to shape some from some Tamiya/Mabuchi or similar motor brushes. I've got some spare brushes from a high power motor that could easily be filed down to the right shape since they're a very soft metal. It'd be fiddly but would work. Other than that, I'd go for some 2nd hand motors from any other Nissan. I'm looking at a set of Skyline motors on Ebay and swapping over the parts I need.

I know this is an old thread but as I was browsing for a solution to this problem, here's my contribution. I just bought the cheapest carbon brush that I can find from our local hardware, and took some measurements from the working one. (i didn't take notes, as I was scratching the makita carbon brush on the fly) I then cut it using dremel, after a few minutes... there you go :) one issue that I experience when I put it back on the vehicle is that it wont go up, but i will go down, I removed it from the window, grounded it to the vehicle and let it run for a few minutes, I think that did set the new carbon brush in, after that rolling the window up is a breeze.
