Quarter Window Problem

[cmkelly]

Hey Gang, Okay, I've searched the forum and all the "window problem" posts have to do with the front windows; mine is with the rear right window. It was always a little slow and took me fiddling with the switch but now it no longer wants to go up.

It goes halfway then stops. When I lower the top it seems to work fine but now will not go all the way up.

I've read about the "amplifiers" but the Nissan parts person did not see one for the back windows. Does the front amplifier control both?

It makes an electrical noise (sort of) when under load so I don't think it's the motor plus it goes down without a problem.

Thanks for any help even, "hey douchbag, use the Search next time.."

Check both quarter windows and see if you have broken plastic part. It look like it snapped and your window is off the track. I might be wrong though.

My driver side rear quarter window does this all the time. It just stops halfway up.

My remedy is to just push/pull the glass up with my left hand while pushing the window switch with my right hand... but I'm too cheap and lazy to fix anything.

Edit: I think the trim around the window is what's making mine stick, but I've never really thoroughly investigated it.

I've tried to pull on it while pushing the switch but it does not easily go up and I don't want to screew anything up if it's off the track or something. I'm going to have to pull the panel off tonight and take a look. Is the backseat panel where the rear speaker easy to get off? I haven't had to mess with it yet.

I also ordered one of those Nissan 240sx service manuals in CD, anybody have any input on them.

Here's a link to a pretty informative thread about the rear windows. It's directed more toward the window going up crooked, but the pictures and diagrams may be helpful for you as well. Knowing how things are assembled is usually the key to diagnosing what is wrong.

Hope it helps!

Post again when you find out more. We'll get to the bottom of it.

If your window is on the track, loose 3 bolts which is K3102 in diagram in above link and adjust whole assembly which is K3294 & K3295. There's an arm that goes up and down and it might be taking too much tension, so it stops going up. Quarter panel cover is easy to take off, but be careful not to break anything. It's like $800 apiece. I've spent lots of time with quarter windows on my car, and I wish I could help you in person... Keep us posted.

Thanks for the guidance. But if you really wanted to help Texas isn't too far from North Carolina and imagine that great top-down drive. I'll even buy you some BBQ.....

[cmkelly]

Okay, more information...When the top down the window goes up and down as it always did (juggle the console switch a little) but when the top is up it labors when it meets the rubber edges. So it appear to be more of an adjustment issue.

With that said, I understand there are 3 screws that can be adjusted to better fit in the track. I'll check out some posts on this topic for more info.

Thanks again.

Iin that thread he listed, you'll where there is a plastic part on the rear most part of the rear window that typically breaks. When that piece breaks, the window will bind about half way up. When I bought my Vert last week it was garage kept with 40,140 miles on it and had a broken piece. It's just a weak piece and I suspect yours is broken as well.

Haha, I do the exact same thing....Difficult to do while driving, but the fact that it's an automatic helps I suppose. But yeah, as far as the cause of the problem, I believe that the piece that guides the window up is broken, or off, and that's what makes it stick.

[cmkelly]

It appears that many people have had experience with this problem. Because mine is sort of acting correctly what is the next step in it breaking? Will it no longer go up at all? The plastic peice, what does it look like?

I have a couple of plastic peices that seem to do nothing but are near where the guides are. I'll take some pictures at lunch again and maybe someone can look and say, "yep those peices are broken." If they're broken do I run some risk continuing to operate the windows?

Thanks again for all the input on this great forum.

Which "track" is the rear quarter window supposed to be in? Here are two pics that who each window in a different track. One is probably wrong right?

Hi, I have searched the forums a fair bit about how to remove those windows from the body of the car but only seem to getting patchy instructions, so my question is

Can somebody please give me a good description on how to remove the window assy from the cavity of the car.

Or even pages from the manual as I carnt seem to get one at the moment from ebay or bookstroes.

Thx......John

I had to search my 100GB backup hard drive to find these pictures. I took them Sep. 2004.

1. Remove rear seats and interior panel. It'll look like this.

2. Raise the window. You have to raise it to access cotter pin.3. You will see 3 nuts holding quarter window assembly. Remove those. BUT, you must mark them, so you can reinstall them exactly the same as before. 4. If you look inside, you will see small cotter pin. Pull it carefully. It's okay to drop it. You can get it later. If you drop it during installation, it's hard to fish it out because window assembly is on the way, so be careful.5. Now slowly lower the window.6. Now you will think there's not enough space to get the whole assembly out, but don't worry. You have to kinda play around to take it out, but you will get it out eventually. Do not remove small rubber cover above door lock. You will break the pins and it won't give you much space. I tried and it wasn't necessary.

That's about it. It's an easy job. If you are having a trouble, stop what you are doing and post here. We will help you.

right side:

I just checked mine and it looks like your left side is wrong. Guide must be broken, so it's out of track and trying to make it's own way up.

It's white platsic piece that's covered with grease. Well, it's white when it's new. Yours will look yellowish. Remove interior cover, ask someone to operate the switch and look the window while it's moving. You will see what I'm talking about. It's okay to use quarter window although the piece is broken. It'll work for a while, but eventually the piece will worn out and give up working.

Another Post brought back frmo the dead ;>)Yeah, you're right 94_240sx, my window is off the track but I've been too lazy to fix it. So far it hasn't failed so I have not had the need to fix it yet. Plus that means pulling the seats....

Softop - I remember a post a while back about someone fabricating a part to fix this; maybe someone else remembers. Good luck and as always post progress picks as you go. That's what really sets this site apart.

[94_240sx]

Found it. Here's the plastic piece. It's a good one. This is on my driver's side and I replaced it when the part was available back in 2001 or 2002.

[94_240sx]

I think I've posted this picture like 3 times already. I had to do this on my unfortunate passenger side. Believe it or not, it works perfect.

P.S.: Arrow is pointing at cotter pin.

This is from vert supplement. You see 'STUD'? There are 3 of them and you must mark where they were before you unscrew them. If not, you have to spend a long time aligning quarter windows.

Found this picture on my computer and wanted to share with you guys. I got this from someone in Japan when I was desperately looking for a part to fix my broken quater window. I was hoping that s13 silvia had same mechanism and guess what. It was totally different. I also visited Infiniti dealership to check out M convertible, and it also had totally different mechanism than 240 and silvia. Among all those three, 240 has the worst quater window assembly design.
