Guide to Lubricating Sticky Rear Windows

Evening All,

As you know as time goes on the runners on our rear window regulators dry out, which makes them noisy and prone to potential failure which in timely and expensive to fix. On of my windows developed this problem so today I've dived in there and re lubricated. I appreciate that ideally the regulator should be removed completely to 100% cover this but the following has certainly shut mine up for now and was a quick job.

The following is instructions of what I did. It took about 30 mins end to end including taking photos:

1. Open the door on the side of the car you want to fix. Unscrew and remove this retainer plate, it’s metal so can be pulled off

2. Remove this retaining screw which holds the inner rubber window seal in place

3. Remove the plastic cover. It comes out by pulling it straight upwards. It’s quite stiff. I started and the front and worked back. I didn’t removed completely, just pulled out of the way.

4. Lift the front of the Inner window seal upwards to loosen it

5. Pull the inner rubber window seal out towards you to remove it. I had to wiggle it a bit.

6. Clean and Gummi the rubber window seal, I put gummi on the lip at the back (yes it’s plastic) as this will help refit in a minute.

7. I hope you’ve got SmartTop at this point. Raise the windows (2 Close clicks). This now gives you access to the window regulator

8. Get some White Lithium Grease (WD40 version was good because of the extended straw)

9. Spray the 3 runners on the regulator. Don’t go crazy but you don’t want to have to come in here again for a bit! I also put a little on the Nylon Runners (at the top)

10. Try the window function. It should be better immediately.
11. Refit as reverse of above but note when refitting the plastic cover there are clipping points. The one on the right in the picture doesn’t go back in without giving it a little push with your finger to guide it in. (the cover will be loose if you missed the lug)

12. Once the Plastic cover is back on make sure the inner rubber window seals not caught underneath it.

I had a small water/ air leak between the front and rear quarter window (driver side), so today I followed the instruction to fix/ lub the window. I ran into a major, strange hipcup/ issue... so a quick job turned into 4 hrs of frustration!!. I followed the instruction to lower the roof, removed the accessories, then readjusted the front and rear windows to the perfect alignment, then lubricated the mechanism with grease (instead of lithium spray).... everything was easy and quick. Then I closed the roof.... strangely the front and rear window were now even more far apart then before, and the gap between them was bigger than before... the alignment was gone!! So now I readjusted the windows with the roof up (to perfect distance and gap).... but when I lowered the roof, the alignment was gone again!! Now the windows were too close together, overlapped on top of other, pushing each other!?? I went back and ford readjusted no less than 20 times!! but the roof up and down positions would change the alignment completely!! I finally adjusted the windows to fit perfectly with the roof up position (where I would most likely close the windows), then changed the smart top setting to disable the rear window up when the roof is lower :(. I couldn't logically adjust the rear window to position properly with roof both up and down!!??. I didn't touch the passenger side, but it seemed to have no problem ( like the driver side)!!??

The images are all blocked, 404ing.

In any event, I was able to lube the tracks with lithium grease by:

1. Lower the roof
2. Remove the metal retainer
3. Remove the upper plastic trim and lay it to the side
4. Remove the rubber inside window seal
5. Raise the roof, close the windows
6. Looking down inside the rear window, spray lithium grease on the tracks

Greasing rear windows runners

Edit: If Optim8 has better pics and description - please feel free to delete this post. Just posted it because I needed to do the job today. The left window was very erratic and noisy. Works fine now:laugh:

I have read this tread - but there was no pictures. So this might come in handy. First you need to get the seat as far as possible to the front.

1. Open Roof fully so the rear windows are down.
2. Remove two Torx 10 as seen here. Metal cover comes off.
3. Remove last Torx 10 as seen.
4. Then start to pry off the cover as seen - start from the front. Be careful not to rip the speaker cables.
5. You need to adress the hatch as seen here - small screwdriver. Pry and wiggle - you will find out how it works.
6. Leave the cover as seen here - away from the roof. You can see where the fitting points are now.
7. Then remove the inner seal of the rear window - take a photo to remember how it was mounted. Pull upward and to the front.
8. Raise the roof with the rear windows fully up.
9. This dark whole is where you need to go with your hand - or with a spray with some sort of grease. I used grease on my figers tips.
10. Grease your finger tips an smear the runners. You will feel them. Don´t smear anything else.
11. When putting the main cover back - make sure the seal is in position.


Tried to get text under each photo - but in vain.
