The two rear windows on my '98 are kind of strange. They work every time I drive my Rover but sometimes it is like they need to warm up; on the first few attempts no switch will move them at all, but then after a few minutes they work very well from anywhere in the car. Other times they work right off the bat as soon as I turn the car on. Is there a simple fix here? Thanks.

 

search 'rear window ecu solder' on this forum... there is even a youtube vid.

 

Sorry to highjack but forum wont let me start new thread. Where is the rear window control ECU for a 2003/2004 ? It is not behind the glove box.

 

D2 window ecu... I believe is part of the Bcu, which is attached to the fusebox. I could be wrong. What does Rave say?

 

It says...

The rear window lift relay is a normally open relay that provides power to the rear window system. It is controlled by the IDM. The IDM receives a rear window enable signal from the BCU to allow operation during the ignition switchedoff timeout period.
Both the rear window lift relay and the IDM are located in the passenger compartment fusebox. The IDM is integral to the passenger compartment fusebox.
The rear window lift relay receives voltage from fuse 13 (30A) in the passenger compartment fusebox. The IDM
controls the earth side of the relay coil.

and my Sunroofs dont make any noise either so...

The BCU enables operation of the sunroof ECU. If the sunroof ECU does not receive an enable signal from the BCU, neither sunroof assembly operates. The BCU is located behind the glovebox. The sunroof ECU is located above the headlining next to the front sunroof assembly.

Time to learn all about my BCU and related fusing ;(
