89 Coupe DeVille, power windows pop off ball joint and fall down in door?

Question

Any time I close a door with a window down or partly down, a balljoint pops out and the glass falls down into the door.

It's happenning on both doors.

Is there a trick here? This is really pissing me off. Please help me.

Sounds like you need new glass tracks and rollers.

There is a plastic runner that slides in the bottom channel and this has ahole in it for the lift ball. This piece is cracked and needs to bereplaced. Not expensive but labor intensive to replace.

You are right I looked and they are cracked. How can I get new ones on without cracking them as well? Trying to put the ball joint back in the broken ones is almost impossible, I couldn't get it to go back on even with force and pliars etc.

thank you for your help

The new ones are more pliable than the brittle old ones. Most of the time,the channel they sit in has crimps on the end. They are not necessary andonly serve to keep the original ones in the channel when the car isassembled. Anyway, bend one end of the channel so you can slide out the oldones. Slide in the new ones, you will probably have to pry them in thechannel over the rivet that will be in your way. Then take big channelocksand if the window is up high enough to get them in the open area on the leftwith the window about 7/10 of the way up, squeese the ball into the plastic.If you are straight in alignment with the ball stud, it should go in withouttoo much effort. Then lube the channel with white lithium or similar. Don'tworry about rebending the end of the channel back, the regulator never goesthat far.
