I've gone through 4 regulators on the driver's window, 2 on each of the passenger windows. Been getting the cheap ebay regulators so far and they appear to be identical to the OEM. Only one motor failure.

I've also replaced the retaining clips that hold the window to the regulator a couple times as they break and cause the regulator cable to jamb up and fail.

This is on a 2003 3.0 X5 that's driven daily and has relatively low mileage of 120k.

Driver's side just failed again at 8 months and hoping for a replacement that will have a longer lifespan. What are other folks using to replace their regulators and how long are they lasting you?
