Front passenger side window. The window goes up and down but tilts. I have the door panel off and don't really see anything wrong or any parts laying down in the door. I can't find a detailed picture or exploded view of the inside of the door. Is the regulator cable driven? Can you give me any insight on what to look for? I also noticed the motor assembly etc., is riveting in?

Sure here is how to change the window regular out.

Remove or Disconnect

1. Window regulator.

CAUTION: Step 2 must be performed once regulator is removed from door. The regulator lift arm is under tension from the counterbalance spring and can cause personal injury if the motor is removed without locking the sector gear in position.

2. Drill hole through regulator sector gear and backplate.

Important
^ Do not drill hole closer than 13 mm (1/2 inch) to edge of sector gear or backplate.

3. Install bolt and nut to lock sector gear in position.
4. Drill out ends of three rivets using 1/4 inch drill bit.
5. Motor and remaining portions of rivets.

Install or Connect

1. New motor to backplate.
2. Rivet to motor at bottom location using ball peen hammer.
3. Clamp motor to backplate using locking pliers.
4. Remove bolt and nut securing sector gear.
5. Supply power to regulator to gain access for remaining two motor rivets.
6. Two rivets.
7. Remove locking pliers.
8. Window regulator.

Is there somewhere online where I can see an exploded view of the window regulator and components? I know I'm going to have to fix it one way or another but there's not much room to work.

It looks like the window rail mount has broken off. It should be down in the door so you can get a replacement at the auto part store.

Well, unfortunately somebody else has been in there trying to see what was wrong with it or fix it and may have removed the broken part as it's no longer down in the door. Did it have a roller attached to it of some sort that fits in the rail?

I don't think there is a roller, there is window felt which is between the window and the window rails. Do the rails look like they are in the correct place?

Seems like a really weird setup. There's a channel on the left-hand side of the door where the window rides up and down on but don't see one on the right. Only the regulator that runs on the track that makes the window go up and down.

Even pushing window into left side track, it still seems like there's too much play where the regulator hooks to the window. That's why I thought there may have been a wheel or plastic attachment that may have been missing there.

Does the windows have felt in the guides? Also, there is a bottom mounting bolts that can secure the guide I would make sure that was not missing.

Not much felt left in the guide. Only two bolts hold on the lower window channel. The plastic piece looks like it's glued to the window on the bottom left. There is a small piece of it missing. The channel is adjusted over to the right as far as it can be.

Do you know what the technical term is for that black plastic piece that needs replaced on the window?

Hi,

No I haven't. Parts store has no aftermarket part(s).

Hi,

Have you tried a salvage yard? If you are looking for the plastic part at the bottom of the window, that will likely be the best resource. If it isn't manufactured aftermarket, that may be the only choice because a dealership won't have them unless you get lucky and find dealer old stock (DSO).

Let me know.

Unfortunately, considering the age of the car, not too many junk yards still have these in stock as they all have been crushed.

I have tried to cross reference other vehicles to see if any parts would fit in the door but all I'm getting on cross reference guides is the two-door model and not four-door.

Hi,

That has to be frustrating. Have you tried glass repair shops? Also, I attached a pic below. Do you see the part you are needing?

Let me know.

That window channel bar and that black plastic piece on the bottom left of the window is what I need.

Hi,

I see it. I feel the only place you will find one is a salvage yard. Here is a link that checks nationwide for salvage parts. You may want to try this.

I actually found a guide on eBay but before I put it in the roller was in really bad shape on the regulator, so I put a new one of them in and now even before putting the window channel and guide back in it only rolls up three quarters of the way and stops. Almost like the roller is binding but it slides back and forth on the track just fine.

Hi,

When you are raising the window, does it appear to go up straight? It could be binding in the tracks.

This is with holding the window straight in the door channel itself without the other track even in.

When you are pressing the window up button and it stops partially up, does the motor just stop or does it continue to work but not move the glass?

It sounds like it just slows down to nothing. If you manipulate the window and keep hitting the button it eventually goes up. Without the window and the regulator moves up and down fine. Only started to get stuck after I put the new regulator wheel on.

Hi,

It sounds like that is where the problem is. When you installed it, did everything go together easily? Did you lubricate all the moving parts?
