Hey Guys,
I just installed my rear power windows on my 71 Challenger and I have a question. I replaced the motors, cleaned everything up and replaced a couple of the plastic pieces that came in the rebuild kit. Then greased everything and installed them.
Everything went straight forward. I marked the locations of all of the adjusting bolts and installed them in the same spots. One window goes up slower than the other and I'm trying to figure out where is could be getting jammed up or is it the old battery that I'm using? The other window goes up better but the one just creeps up and down.
Is there any particular area I should be looking to make the window go up and down easier? Thanks
Dave
Could be just an old tired motor? Were they operating the same when bench testing them ?
Are you powering them through the switches or directly off a battery with test leads?
The motors are all new and I'm using a Power Probe to switch them on and off.
Well then it sounds like it's binding somewhere, check the guides, make sure they're sliding on the correct position. :dunno:

Yup, something is binding... As Alan mentioned earlier, how did they run out of the car? New sliders aren't always better, the originals often fit better...

I agree with that....power windows especially need to be loose...for less resistance
The old motor was dead so I have no reference point. Like I said they went in smoothly and everything fits well. I couldn't use the old sliders they were pretty much thrashed. Looks like the windows got used pretty good over it's lifetime.
Are there any specific locations that I should be looking at to make adjustments to loosen it up?
Take the center bolt out, disconnect the drive arm & reinstall the bolt.... How does the window slide? The fact the motor was smoked makes me think it was binding before too....
Do both regulators have the large coil spring on them ?
Is this the center bolt you are referring too? Is their a specific adjustment/tension for this bolt or do you just tighten it down? It seems odd with the spring and all. Thanks again.
That's the center bolt, but I was wrong, it's the rear bolt you should remove.... Basically I want the drive arm from the regulator detached to isolate whether the binding is in the window tracks of the regulator....
There is no adjustment or the center bolt, just tighten it down, the spring allows things to move a little to reduce the chance of binding...
Here's your problem right here....The plastic slide is sitting on top of the track and not in the proper groove...

Good Eye!! Yup I agree 100%...
Did I solve the problem? Yes and No... Here's the update:
I haven't had a lot of time to work on it but here's what I did do. I went out and bought a new battery and tested it on the window that I knew worked well and with a fully charged battery the window screamed up and down. Worked perfect. The old battery that I was using was about 10 years old and couldn't be charged any longer.
I didn't test the window that was going super slow because I wanted to look at it one more time for binding. I didn't want to hook up the strong battery and hurt something inside if it is binding somewhere. More to follow.
You did read that the window is in wrong? Before you break it.
I posted my response to Anlauto last week but I guess it didn't post.
The picture that I posted was taken earlier in the day after I noticed the slide and corrected that prior to the post. Sorry about that.
Ah, okay.
