Hey,
I have a 98 V70 and the other day my windows, mirrors, and sunroof all stopped working at once. Does anyone have any ideas about what could be wrong, or what to check? I've taken apart all of the switches, cleaned the contacts, etc. I also checked the circuit breaker and swapped it out with another one and still nothing. Any ideas?

Thanks!

There has to be a fuse or something out to loose all at once.

 

Thats what I can't figure out. Everything I have read states they only have the circuit breaker, which cuts the power if the windows, sunroof, or mirrors run into anything, but it is supposed to reset after 20 seconds. I swapped the window circuit breaker (#37) with the power seats circuit breaker (#38) and still nothing. The power seats work with either. Any ideas where there could be some other type of fuse?

 

Did you check all the fuses in the fuse box?

One has to feed the circuit breaker I would think.

 

Yeah, I have no blown fuses, and according to all volvo documentation that I have checked there is no fuse, just the circuit breaker under the back half of the fuse box, if you remove the torx screws.

 

Then it would have to be a connection at the battery or on the junction at the fuse box.
