Driver's window stuck!

Suddenly, last week, my driver's door window became stuck in the fully open position. Here's what happened:

Name:  Door window.JPG
Views: 509
Size:  59.3 KB

The stop pad (noted in blue, a 2" x 2", 1/2" block of rubber with a plastic cover on top) got old... the plastic cover fell off... and the carriage plate dug into the rubber, farther and deeper than it was designed to go.

Now, the window glass lift arm is jammed and is preventing the motor from moving it.



Seems as if all I have to do is unbolt the motor and free it up. SEEMS like!



Trouble is, I can't get to the lower fixing nut (also noted in blue) on the motor mounting plate with the arm all the way down... it's in the way.

Can anyone give me any tips on releasing the motor?

(Suggestions that involve breaking the glass or drilling any fiberglass will be rejected out of hand...)


TIA.... (I just needed to rest after working on this for several hours, thanks for allowing me to vent.)

Is it possible to just lift the up a bit into it proper position and raise the window?

No. I've tried raising the arm by hand, and also tried applying lift pressure to the arm with a bottle jack. (<--- luckily the drain hole of the door is right under it).

It's the arm that is stuck. I was able to finagle the motor enough to turn its spur gear 45 degrees in case the motor had a 'dead spot'. No such luck.

I can't release or move the lift carrier or guide track 'cause the glass is in the way.

Maybe possible to drill out one end, haven't seen one in a long time but are there not rivet style attachments at each end of lift arm?
good luck in your quest!

That was my thought since Esprits don't really detract the window downward completely.
I think pulling up with your Lead Tech aka Pat hitting the button and maybe a bit of a tap on the lower arm down near the bush would do the trick.
But if that doesn't work I have a really neat Hitachi Grinder and I could open up a large area to work with surgeon like skills.

They got it all in there so there has to be some sort of access available. I am able to get into mine but it is a G car. and certainly different.

FYI,, My tracts need to be cleaned, driver side is getting a bit sluggish i noticed. Must be all that rain from B Ham getting washing dust down in there and the ride home.

In a few minutes I'll be attempting to reach that stubborn nut on the bottom again. It is impossible to get a socket or box wrench onto the nut because the window motor fixing bracket prevents the tool from fully embracing the hardware. (Only allows an open-end wrench held upside down)

I'll have some duct tape and maybe some contact cement at the ready!

(The Lead Tech is still away, but @glb has offered to come over and help later.)

I hear in my distant memory,, Lets pull the engine and a resounding,,"NO!"

If it is that hard maybe just buy a whole door and replace it?

Sure...soon as I install that Superbird rear wing that Jenna got for me.


Jenna: see how difficult it is to pull the motor? (Yeah, it's a window lift motor, but still...)


Other chores got in my way this morning. Will advise everyone of progress (or not).

Odd that its stuck as i have come across several where the whole block was missing! As the motors limits are controlled by a thermal break the motor will not run if the resistance is too high, i would suggest applying the jack method you mentioned while someone operates the up switch. I have a bunch of unusual wrenches for such a problem but they are a long way from you !

Wow...now that is what I call a Lotus wrench set!
I've seen some curved variations in the past, but never quite to that extreme.

Is there a name for it? Where does one purchase such a magical set?

The jack method sounds like the way to go.
Good luck, Atwell!!!

It's 35 year old white grease that has turned to paste. Plus the lube in the gearbox on the motors. You'd be surprised how smooth and quick these windows can be with a little maintenance.

I have several curved and S-wrenches but none like the open-end one below.



Doesn't matter, because what I DO have are wobble extensions. I was able pound a socket onto the lower nut and the wobble allowed a small ratchet to twist past the motor.






+++++++

So, here's what I'm up against: The window is VERY tight in its rearmost channel, the last (lowest) 5 - 6 inches of travel. I'll be working on that, plus testing the motor by applying 12V to the two leads (RED lead drives the motor down, I believe).

The passenger side window (which still works ) has always gone slower the last few inches, too. So I'm not sure if the tightness is an actual issue or not.


Stay tuned.

EDIT: I agree with Mike regards maintenance of the window mechanism. I had cleaned and lubricated my windows, motors, and door latches within the past year.

Have you already done the relay upgrade? What i always do (i didn't suggest it, you said no cutting or drilling) is to drill an access hole on the inner door case, obviously in line with the lower nut (see below) then its easy peesy and no one but you will know its there.

Yeah that hole is a good idea. Couldn't do it for removal as the segment gear blocked that path. My car has wire harnesses P-clipped to the inside of that area with rivets.

I noticed you had a u-joint on your ratchet. Those things are so much bigger than the wobble extensions.


Still stumped as to why the bottom few inches of glass travel are so tight? I cleaned and lubed the channels to make sure. I even moved the channels a mm or two with no significant change in the excess effort.

+++++++++++++

With the motor out, still no workie. I think the motor died (but I never heard of one just failing 'all of a sudden'...usually they go slow, first.)

I may be stating the obvious, but you checked the fuse and both relays are plugged in, right? (I only ask, because the wife nailed it with my issue https://www.lotustalk.com/forums/f164...-issue-408473/ see post #10)

Thanks Jim,



First thing I checked was the fuses. (#30 & 34 on my car)


No relay kit installed.

I applied 12V directly to the motor leads before I removed it.
