Problem with Power Windows V70-XC70

Hello Forum,

I have a problem with my power windows that seems to also be affecting sunroof and power mirrors. They wont function, but every now and again I can get them to move again but only for the duration of maybe half a full window roll up or down. The problem seems to be with the driver window control. When I press it down I hear a pulsing noise and it is hard to press almost as if something is in its way. When pulling it up its very easy and there is not the normal tension you would feel. All other window switches "feel" fine, but dont work either. Initially I thought it was the fuse, but the fuse for windows/sunrooof is a circuit breaker fuse and not easily accessed in the fuse box. But then since it still works occassionally would it be the fuse?
I took my car in last week to have the brakes looked at and they washed the car and seemed to have fixed the windows because they were working fine until yesterday when they started to act weird again. Another thing I notice is that after startign the car is when it seems that I sometimes am able to get the windows to work again for that little 5 seconds that they do.

Anyone have any idea waht the problem could be, steer me in the right direction?
Electrical problem? Battery? Fuse?

Thanks

    The problem is almost certainly the driver's door switchpack. You didn't mention that you smelled smoke or a burning smell when using the switch, but I bet you did. Mine smoked a few times before finally dying.

    The short in the driver's switchpack causes the circuit breaker to trip. This is what is keeping the sunroof from working (also the power mirrors, if memory serves).

    Replace the switchpack. The $110 dealer price sounds right. I found one on ebay for $80. You can just remove the old one without taking off the door panel by sliding tape-covered thin screwdrivers in the sides and pulling out.

    Good luck. Let us know how it turns out.

    More than likely the master switch on the driver'd door has corroded contacts from moisture etc. over time. First try is to get some electrical contact cleaner spray then using the plastic straw squirt liberally into the cracks around each switch while moving them up and down. You can replace the switch; last one I purchased was about $110 from the dealer.
