Window Regulator

[yellowgizmo99]

hey Tom see if they will throw in the regulator, can maybe use it to work up a fix on the guides.

[tom4bren]

I thought about that but I didn't want to use the same pieces that keep breaking. What I'd ideally like to find is something that is available nation wide that could be clipped or glued on.

IIRC someone found out that the plastic clips that attach the glass to the regulator are fairly common parts. Maybe these guides are too.

[yellowgizmo99]

that's what I was thinking, just thought if we had something in hand that didn't have to stay in the VX might be handy.

[tom4bren]

I'll start with the extra drivers side regulator that I have on hand. The parts should be the same for both sides.

My regulator is new....and I didn't install it, but I thought those white thingies were part of the new regulator. You'd think with all new parts, it would work...at least for a while. Maybe I should take it to the dealer and let them figure it out? Is this a common problem to other Isuzus?

[tom4bren]

Those white guides were part of the new regulator. They may not have been in proper position when it was installed. Once the regulator is in place and the glass attached, those guides should stay in place (at least until the keeper part breaks off).

I don't know if other Isuzu's had similar problems. IIRC most other Isuzu windows are flat while ours are curved. That may make the problem unique to the VehiCross.

If I can get out of work early enough to hit the parts store, maybe I can come up with a quick solution for you. The regulator I'll be 'operating' on is an extra so if I can fix it, you can beta test it for us.

I have been staring at the picture for the past 48 hours. I can't think of a solution besides making that top guide clip thingy deeper. But you're right... My Mechanic may not have installed properly. I might try to unassemble completely and do it again.

I hate that you have to go through all of this ... but on the bright side, you'll know more about the guts of the door than most people on the forum.

My recommendation is to unbolt the glass from the regulator. Get the guides back on the track. Bolt the glass back to the regulator. Run the window up & down a few times before you put the door panels back in place. Don't forget to add more lubricant (lithium grease or graphite) to the tracks before you close it up (this is the rare occasion where "mo' is betta" ... you can't put too much lubricant on our window weatherstrip).

When you unbolt the glass from the regulator, it may be helpful to have a couple of suction cups on hand. Push the glass all the way up & put a suction cup at the front and back of the glass as low as possible. When you let go of the glass, the suction cups should hold the glass out of the way whilst you are working on the regulator. Don't laugh. The drivers side winder on my old Land Cruiser was held closed by suction cups for several years that way (yup, Toyota didn't get their regulator any better & it went KA-BLOOEY ... different failure mode though). It even made it through inspection that way.

EDIT:

You may find that after you get the upper guide back in place, you can do the washer thinggy to keep it aligned properly. With the top guide off, that part of the regulator is being held at an angle which is causing the lower guide to have more pressure on it.

it went KA-BLOOEY

is that a technical term mr. enginerd??

[Allison3371]

I'm still staring at the picture. haha. I'm thinking if Tom's genius regulator mind can't think of what can possibly help, I'm taking it to Little Joe's Isuzu on Friday. I would like to think they would "have" to find a way to fix it.

why don't you take some pics and post them. That should really help the enginerd I'd think.
Let me know if you need help on how to post pics.

I put one on the thread I think on page 3. I can take more Thursday when I'm home.

[tom4bren]

I checked out my spare ... 'deformed' regulator. It looks like only one of the little white plastic guides is the problem. It's the lonely one ... the other side has two. The two guides (IIRC on the trailing edge of window) are much beefier than the lonely one.

Any-hoo, the white guides don't look like they can be removed and certainly not available at my corner store auto parts place.

So: I went to my local Ace Hardware (LOVE that place ... sorta reminds me of a Mayberry RFD setting). After perusing the aisles for a while, waiting for inspiration to hit me, I came across some small pulleys. I'll have to modify them to make the groove in the wheel deeper but I think I can come up with a fix for around $10.

I'll put on my enginerd hat when I get home tonight & let you know how it works out tomorrow. The only real problem I foresee is finding some shoulder bolts the right size (hello Fastenal ... here I come).

I'm trying to keep this 'fix' as bolt on as possible so anyone could replicate it for themselves.

Allison, do you want to 'beta test' the repaired regulator? Since my VX is in the shop for at least a few more weeks, I won't be able to test out the fix.

[Allison3371]

I'm game for anything you think might work. I really appreciate the help!

Stay tuned for some "worn out to a split" photos!

As promised:

This is the outside (metal channel side)



This is the inside (glass side)



If you disconnect the regulator and move the window up and down with your hands, you can really feel the play in the "worn rubber" area.

So we seem to have a fundumental disagreement, Kat thinks this is caused by window "track" being too tight and I think that it is caused it by it being too "loose"! Could we be looking at two different problems? Afterall, she can't be THAT wrong!

Did Allison replace her "glass run" with actual NEW or used parts?
