Window regulartors... Why do you hate me so much?

[Dking05]

Really, whats up with these things? The other bimmers, E39, E38 didnt give me too many issues, but this E53 is burnin em' like crazy!

Each one has been replaced twice already, except the front pass. Now i need to replace the rear ones again! I sware i just replaced one like 3 months ago

Anyway, is there any solution to stop this darn things from ever falling again? Also, did BMW ever "update" regulators for the 04-06 years?

silicone spray in the vertical jam where the window slides up and down to release friction

Do you often close the doors with windows down?

I am convinced that avoiding closing the door with the window partially or all the way down is a good preventative step. This approach likely won't totally prevent it from happening again, but I think the regulators and clips have an easier life this way!

Actually I hardly do, ever since the second one, i have always kept them visable. But, lol, they still fall once the regulator moves.

got me on this one, my X is coming up to six years old and never had the problem.

that said NO ONE slams my doors, and where i live we rarely have the windows down,

(A/C on most of the year)

so i know people have problems but i dont know why, maybe you live in a cold area and they get brittle??

[Dking05]

Its a mix of both.. 90-100 summers and 10-30 winters (extremes)

Replaced once again.. Hope they don't go bad -knock on wood-

Agreed. Avoid slamming the doors hard would help, especially when the window at down position.

The front/pass just failed the other day, the window dived right down to the bottom. After taking down the panels, I noticed the screw with the clip bolt to the regulator (on both ends), had been dis-placed out of the regulator. Problem solved after I replaced the clip and bolt it back together. So the regulator was working fine.

The dis-placement was probably caused by the force from the door closing, when the window was open. I had the windows open more often recently because the air-con is waiting to be fixed.

But both my wife at the passenger side and I are aware of this issue and have been very careful when closing the doors...... and it STILL fails. There's definitely a designer issue here.

i wonder if you have wrong fuses and too much current burns them out? or bad relay switches? check it with voltmeter that's where i would start
