over the course of the past few months, the passenger side window switch of my wife's '07 Si sedan has gradually become pretty erratic when going up. sometimes it'd take a second...sometimes it'd never go, others it'd work normally. no rhyme or reason, but it has been really bad lately. through it all though, the driver's switch for the p-side window has controlled it perfectly, so that narrowed it down to the p-side switch.

i know they are only 45 bucks or something, but i took it out, carefully popped the top portion off of the switch assembly (that was a real pain) and sprayed the crap out of the switches with RC motor spray. i pushed the "up" portion back and forth when spraying to assure the spray got inside the switch.

after letting it dry, i put it back together and it seems to be working fine. we'll see as the car goes through some temperature and humidity changes.

 

Sound like you nailed it! Spray some dielectric grease in there if you can get it in there.

 

thanks, unfortunately it started to act up again a couple days later. looks like i'll be replacing the switch at some point. adding it to the list of parts that need to be replaced on this thing!
