I was having the same problem getting 1999 Subaru Legacy Outback driver's power window switch to raise the window up. $180 for a new late model Subaru power window replacement switch was ridiculous.

I was able to refurbish switches good as new WITHOUT NEEDING TO REMOVE DOOR PANEL.

Parts: 4 x Q-Tips, 2 x wood shish kabob skewers, rubbing alcohol, 2 fine screw drivers (Flathead preferred but not necessary) and a little patience & ingenuity...


1) used small screwdriver or plastic knife etc to pop off the trim piece surrounding the driver's door window switches.

2) used small screw driver to gently pry black switch covers off of the switch rockers below.

(I found it easiest to place small flat head under the middle/side of the black switch cover).

3) use small screw drivers and slide it between the middle of the rocker switch pivot bump and the white plastic with the hole that receives the switch bump. (*Note: you need to detach the switch from the white plastic receiver...not the black plastic cover over the pivot point).


5) gently lift out two metal connection pieces under rocker switch. 5) use q-tips / kabab sticks / screw drivers and rubbing alcohol to clean scrape off all dirty black build-up.

6) re-install in reverse order... good as new.

I found the part last summer but didn't have the guts and thought I'd break the clips. I used wire strippers like RKS suggested and they worked fantastic. Thanks again Joe, I wouldn't have tried it on my own without this instructable. Yea now I can open my drivers windows without pliers!

Joe, just in time, I found your very clear instructions. I was "on the verge" of dis-assembling the entier door (looking for the wrong problem). Instead, I switched the polarity as you suggested and the window ran right back up. It's a really nice day here, and now I will get to enjoy some of it. Thanks, Pete... Doylestown Pa.

My window would go up and down but not all the way and the movement was sloppy. This instructable showed my how to get at the window workings. I found a couple bolts had come off. Replaced them and tightened a few others. Works perfectly now! Took 15 minutes and probably saved me $100. I used a pair of wire strippers as a panel removing tool. They are like very thin pliers, slide easily between the panel and the door frame and provide lots of surface area for prying without causing damage.

I like this sort of instructable. Too many products these days seem to be specially designed to defy being modified, fixed, or even opened by "amateurs"; it's good just to see how to get into them. A "panel remover" is the magic tool, eh?
