I just wanted to thank anyone who posted about repairing the window motor by simply cleaning it out and to let everyone else know that, for me, that method worked.

It took about an hour, but it saved me the cost of the new window motor and possibly the installation.

I took the door panel off and apart using the directions and instructions on the site and in a post, and then removed the cap from the motor. I then removed the internal part, cleaned off all the carbon residue and put everything back together. Before this, my window would not work most of the time... and banging the door sometimes resulted in the use of the window for a bit...

Now the window works again every time.

Thanks everyone!

CK

Update: After a few weeks the problems have resurfaced...
Here is a great HOW TO article written by SmoothZ for taking everything apart and getting at the motor.

I need to do that soon, probably on Memorial Day weekend. I figured that cleaning it first would be ideal before going to the dealership and getting ripped off.

Okay I fixed my window... Sorry I didn't talk pictures for a walk through... But it wasn't hard at all.

Here is what I did.

Remove the Door Panel (See instructions for that).

Once you have the door panel off, leave the cables connected to the door panel and just move it so it's out of the way.

Now remove ALL of the black 10mm bolts from the silver door panel.

In the Z the window AND motor are all bolted to this panel.

Now remove the 2 upper 10mm bolts (Gold in color)

Also remove the 2 lower 12mm bolts (Gold in color)

Remove the 3 10mm bolts that hold the motor to this panel. (Note we aren't removing anything... just getting access to that pesky motor)

Slowly pull the silver panel away from the door. Note... It has the weight of the window on it. So do this slowly. Once pulled away there is one cable runing to the back of the door on the upper track. Unsnap it from it's plastic (white piece) so it's not in the way.

You will clearly see the motor as it faces UP. There are 3 phillips screws. Remove them and pull that housing with the stator (The part of the motor with the windings on it) out.

Now you will probably see the problem with your window motor. The brushes rub against the communicator (The brass/ copper part) and mine was caked with grease/dirt. I cleaned mine with WB40 to break up the grease (carefull not to remove the grease/lube from the end of the shaft). I then took sandpaper and sanding these contracts back to their orginal copper/brass color.

Once done: Replace everything and enjoy your power window again.

And the money you just saved.
That worked like a charm for me... the hardest part was getting the panel to come off nice and easy and then putting the inner panel back together... but it wasnt an impossible tast.

For anyone that has window problems and a slight bit of mechanical ability - I highly suggest trying this first before spending $300+ on getting a new window motor installed!

Hopefully, I have time tomorrow to try this out since I'm having major problems with it. I plan on taking pics and posting them.

That would be extremely helpful! Looking forward to trying this out during the summer (in a month or two). My passenger window is causing a few problems and I'm quite sure the motor is fine, just dirty.

Good luck for the window! :)

Interesting that the problem came back. I guess if it happens to me, I'll just take it apart and clean it some more.

Where I'm from, a new window motor (and everything else that goes with it) + manhours = about 900$ :(
That's crazy! I could do the work myself, but I'll have to shop around for a new motor. I definitely won't be buying it from the local dealership if they charge too much.

I'll try cleaning it one more time, except much more thoroughly. If that doesn't work, I'll be forced to buy that. Thanks for finding it.
Hey SmoothZ,

I was at the dealer yesterday getting an alignment and asked about the window motor.
It was $375 for the motor and $512 installed (I am in Canada)

I saw a few on Ebay for around 180USD and I have found a few at the wreckers for around $170 but I am concerned that they might have the sam problem because of their age.

Someone else gave me an idea to take it to a local motor specialist and see if they can do something with it (rebuild?)...

I might try that too...

I just hate the idea of tearing that whole door apart agian, putting it back together, and then having things not work 2 weeks down the road... I would rather just put the new motor in.

CK,

If you go that route with a specialist, let us know what they have to say. Tell the specialist that a lot of owners are having this problem, and you'd like to know for the sake of everyone how this motor is failing or if it can be fixed locally.

I might just have to find a reconditioned one, which is probably what the specialist does anyway for these companies that sell them.

I must say, I am staggered by the windows on this 350Z... I got a Opel Corsa with a 160000 km (about a 100000 miles) and the windows work fine! Never changed ever!

Anyways, I asked a local mechanic about my window problem and he even said that I could try another motor (didn't have to be the overpriced Nissan one) and that rust (if the window isn't used much) + gunk could be a possible reason for the motor failure.

Personally, I think I'm going to take out the motor, dump it in mild citric acid (cleans very very well!) and get a heavy duty lubrificant (not WD40 which I would normally use).

But if somebody finds out a better solution, please do share ;) I'll post about my results when I finally get around to doing this.

I got my replacement motor today from RockAuto, and I only ordered it yesterday! That's fast! But anyway, I went to work installing it, and prior to installation, when I pushed down on the button to lower the window it once clicked as if it wanted to do something. Now, it does not click. I installed the new motor, and it still does not click, nor does it move the window. I can, however, lower the window halfway by holding the unlock button on my keyfob for five seconds, and, if the window is at what it considers to be full height, when I close the door it will go up like it is supposed to but then go down halfway. I am stumped, mainly on why the window does not go up or down when I push the button on the driver or passenger-side door. Anyone who has previously installed their motor have any hints/tips?

Well, I would be interested to see what happens with that Sandok... my guess is it would work for a few weeks like SmoothZ and mine did, and then die out again. When I actually had my motor apart I noticed that there was wear on the copper areas that are designed to transfer the electrical current. My guess is that once this starts to wear things dont sit correctly and cause the motor to work intermitently. Cleaning out the crap on the inside allowed for a cleaner area and a more consitstent connection until things were dirty again... then the slop of the motor causes the same problem again.

I would think that the switch and motor are completely independent...

I would try removing the passenger panel where the switches are located and see if the click goes away... my best guess is that the switch is actually broken.

I was also wondering if someone can sticky this thread...

I think that the "window motor problem" is enough of an epedemic that one thread with most of the info that we are working through would be valuable.

Thoughts?
