Rear electric window stuck (down)

[Rocket Dog]

OK, so i think my rear window finally gave up the ghost. it 's stuck down in the tailgate. I have already changed the swtich and checked for power and both are good. So I am thinking that the motor finally gave out.

My questions is how can I get the window to roll up if the motor is dead? I pulled the access panal off and can see a way to either roll up the window or remove the glass.

Any one have a suggestion? I don't want to brake it by pulling on it.

thank fells.

You are sure you've checked everything ?
Are the wires still connected to the safety switch ?
You have power at the motor in both up and down positions ? (polarity will reverse)


Mine sticks down a lot. With mine it is the motor. I have new switches front and rear and have traced all the wiring...

I have to use the dash switch and quickly go down-up... down-up... (holding up to see if it moves) until it moves up again. Its gotten so bad over the years Ive had to drive with it down occasionally, but it eventually does go up.

And Eds has a scary "Jump" In it! Makes me feel like the back glass is gonna shoot right out of the bloomin track and shatter on the ground... I second checkin the safety switch. It IS quite possible the motor is fried tho...

On a side note, Kris. I believe Blackbarts quote is incomplete. Should it not read "Anyone can restore a classic vehicle, but it takes a real man to cut one up and have it end up looking better than the day it was manufactured!"

... Jes sayin....

Have you tried having someone give the tailgate a good slap while you hold the switch in the up position ............ yes, I am serious.
If that works, the brushes in the motor are probably worn out. You can take the motor apart and stretch the brush springs a little - then it may work for a couple more years. Yes it's a PITA, but it doesn't cost anything.

thanks for the imput, but one of the wires (white) is dangnaling (disconnect) not sure how to reconect it with the glass down.

I also jump the safty switch, it's how I seen the cabel danganling.


any idea on how to lift the window? I can't pull it and as far as I can tell the track wont come off.

[Kris]

If I remember right, the safety switch wires are white. You cant get to them with the glass down. You may be able to pull the switch but theres not much slack in the wires.

Well, if it comes to it the first thing to do is get the glass out.
It is held onto the regulator arms with push clips. They like to go on but they dont like to come off.

Ive reused mine every time but if you break or lose one, now you know where to get replacements.

I do mine with the tailgate open and the window half way up so thy are inline with the access panel, but you may be able to get to them when it is all the way down.

Best way Ive figured to get them off is using a needlenose plier as a wedge to get under the clip on both sides of the post. They are very stubborn. Give yourself alot of time as you will be working by braille. Once the clips are off, guide the window channel off the posts and then pull the glass out.

I used a 2" holesaw to make a access hole, then use a electrical panel
waterproof plug. with a little custom bending.

yeah- mine got stuck, one of the window 'clips' fell off into tailgate.
This allowed the mech to overshoot the safety switch and thus disabled the motor. Pain to sort out . But dirtwags advice is good too- on another occation my window wouldnt raise- all because the tailgate was very slightly open on the side with cutout switch. Took a while to figure out but after opeing door and buping that side back it worked fine. Once your in there its worth cleaning all the old yellow grease off, and re-greasing the whole mech and cable tying the loose cables out the way .The mech can chop them up (like my heated window cable). I also removed handfulls of pine needles and rust that built up and sprayed the lower seam with litium grease to stop rust.

I would unplug the wiring harness just under the vehicle at the drivers side up under the tailgate. Take a jumper cable or a battery and strip some heavy duty wires (8-10 AWG) and jump the Tan and Brown wires to the plug going to the tailgate. Connected one way, the window will go up, reverse the connections and the window will go down.

Those motors are pretty solid, most likely it is the wiring, especially if the last time that the window operated it seemed normal.

I can see a white wire that seems to have been connected to the motor somehow got pulled off the motor or just broke off.

it' not the safety switich becuase I jumped it and then used a flash liight to look around all I can see is just one wire connected.
Also when I took off the panal it laid on the taileget toward the motor.

I'm going to try to take the window off the track tomorrow. hope I don't brake the glass

just wanted to let everyone know that I was able to get my window back up but discoverd that the white wire actully broke off the terminal. I was able to rig it back in to keep the window up....

btw I took off the motor and that thing was under some real spring pressure. the dam think almost busted my knuckles when the track bar shot up......


so I need to fix the connection to the motor which I am sure I will need to buy a new one or get a parts one for the waggster.


thanks everyone.
