Hi all I just went in and got my #1 inspection done and they told me
that my power window regulators were in need of replacing and they want
386 a piece to replace them. The funny thing is that I dont think its
the regulator but rather maybe the rails it rides on or something. It
seems when the window is in the about halfway up it starts working
normal. But when I get below the half way mark of thw window frame the
window goes down normally but has a big problem going up, very slow
until it gets halfway up when it starts acting like normal. Im
wondering if someone else has experienced this problem and how they
fixed it. Or does anyone know how to take the door apart to get to the
rails and regulator?
I agree with you. The regulators themselves should not cause this issue,
unless of course there is excessive play in the regulator linkages, which
could possibly cause the window to tilt and therefore leading to excessive
What is it on the regulator that would cause so much resistance? Is it not
possible to lubricate them?
Actually, now I think about it I was picturing the old type regulators, are
these regulators cable driven?
Yes. The problem is a caused by a [insert your favorite adjective here]
nylon or plastic retainer progressively breaking off the cable until it
fails completely. Lubrication will not help. Don't bother to take off
the door panel without the new regulator in hand.
Trust me, it's the regulator, which on E46s includes the rails. Their
durability is terrible. (We have a 1991 Honda Accord with 180K or so on
it...and its original window regulators. My wife's 2002 E46 with 70K or
so on the clock is about to have its third new one. Grrrr....)
Make certain you disconnect the battery before removing the door panel
to de-energize the airbag. The door panel is retained by the usual
kinds of clips and some screws. (Remove the screws first, of course.)
Follow the proper procedures with the airbag, which you will have to
remove. If any of this sounds foreign, pay to have it done. I forget
exactly what tools you need but a set of wrenches, a socket set
including a 10mm socket and at least a short extension, a #2 Philips
driver and assorted Torqs drivers, and an appropriate tool for the door
panel clips will probably get you through. Oh, you will also need a
small wire tie, and have to remove the motor that drives the window to
remove the regulator.
