Drivers door power window switch repair

Does anyone know how this compares with the disassembly and cleaning for an 850 master window switch (center console)?

It's pretty much the same procedure.

I did a write up here http://www.volvoforums.org.uk/showthread.php?t=114576 a while ago, but without pictures.

If you refer to the above pics while your doing the job on your 850, you should get the same result.

It does work. Everyone should try this before replacing any window switches.

Thank you very much for this helpful post. I tried all the above for cleaning the contacts but to no avail. Both right windows were still ever so slightly finicky with the switches, with the odd little puff of smoke. So can't have that... just ordered a Dorman part, new, off ebay to replace it. Part # Dorman 901-550 Door Window Switch. Cost $108 USD, and $30 to ship.

Wanted to get new because you'd have to assume a used one will come with the same grime in there. My local volvo parts guys (http://www.chapmanmotors.ca) quoted ~$100CAD used and $200 something new.

Will follow up and let everyone know how it went once it gets here and in the car.

So the Dorman switch arrived today. I snapped it in, and all windows in the car now work 100%. If it offers any help to anyone else I got the part off Ebay, member "ecaronline". Thank again for this post.

Before you take on this project, I suggest an easier, and potentially immediate solution, should you need to fix the switch in a pinch.

I cannot believe I fixed anything on this car with a jiggle, but, I did. My RR window was refusing to go up. I poked around on the interwebs and found that twenty to thirty quick up down motions of the switch might be enough to clean the contacts. I was able get the window up quickly and easily.

Maybe someday when I have nothing else to do I'll follow this thread. In the meantime, the kids are forbidden from opening the windows.

Thanks for the exhaustive detail, and help. This place is GREAT!

Yep, definitely a design flaw. Thanks OP for the write-up with pics!

WawHOO. Pouring Rain, driver's window stuck all the way down. Followed the instructions and BAM, all is good. Thank You.

Excellent step by step description. BUT, for those owning the V70 or V70 XC on the S80 chassis (mine's a 2002), the switch is electronic, and does not have brass contacts. The bad news is that it fails in the same way (ain't progress grand?). I found this out the hard way.

First, the switch is secured to the inside of the door panel with a torx screw and washer into a plastic boss, clipped into the panel. Using the "if it doesn't fit. force it" maxim, I prised the switch out, breaking the attachment boss loose. Don't worry, it really isn't needed. The clips on the switch itself do a great job of securng it to the door panel.

I disassembled the switch per the instructions, but found a circuit board where I had expected to see brass leaf contacts. On the reverse side was a rubber pad, covering many electronic switch pockets. All Stop! I cleaned the dust out of the switch and reassembled it, wondering whether I had destroyed it.

I reinstalled it in the car, and lo and behold, everything worked perfectly. I must have inadvertently gotten a connector pin cleaned, or some of the dust I removed allowed something to work.

I'm an engineer, so I want to know what I did to get this working, but you know, I'll take it. Saved me about $400.
