Hello-2001 V70 T5 Wagon. Reading lights,vanity lights, sunroof, not working.Checked all fuses. I believe I am getting power to the circuit board (courtesy lights work) but no power coming out. This is the board in the headliner where the sunroof switch is located. Wondering if anyone has had this problem ? Thanks in advance for your response

 

Did some quick research in the 2003 wiring diagram and it looks like there is a common module. Something called the UEM which seems to connect to the sunroof and overhead lighting. On the 2003 V70 the manual says that it is located behind the rear view mirror but I am not sure about that.

 

Try locking and unlocking the door with the key/remote a couple of times and see if it helps.

BTW the UEM is the rear view mirror.

 

Thanks for the responses. Will look at it again Saturday and keep you posted. Thanks again.

 

I read something about information from the UEM needs to get downloaded to the new UEM if it gets replaced. Is this in fact true? Changing out the mirror assembly is straight forward but it seemed like the car would have to go to the dealer for the download process. Any and all insight on this would be appreciated. Thanks in advance.

 

Yes software would need to be downloaded.

 

Thanks tech

 

I had the same problem and tech's advice helped resolve it. However, I am not able to get the sunroof to go to auto close.
Mines, an '01 V70 T5 and when I push the rocker foward for auto close it closes and then bumps the roof up into vent position. When I pull the rocker down it goes down and bumps right back to vent.

Any ideas?

 

Maybe the motor it times wrong.
