RAF_gti 0 Posted October 18, 2008 I've a wee bit of a problem with my windows..they don't bloody work! Neither passenger or drivers side work, from the switches on either side, what is common to them? Do they go through a relay and of so which one? There is a black plastic box under the dash (window controller), I can't find any mention of this in Haynes! thanks! Steve Share this post Link to post Share on other sites
chrisj21 2 Posted October 19, 2008 Fairly common i would say due to the age of most gti's nowdays. Neither of mine worked when i got the car, most likley to be the motors in the doors. I've replaced my drivers side but yet to do the passenger one. Also worth checking the wiring to the switch too. Chris Share this post Link to post Share on other sites
large 33 Posted October 19, 2008 I've a wee bit of a problem with my windows..they don't bloody work! what is common to them? Fuse? Share this post Link to post Share on other sites
Ryan 99 Posted October 19, 2008 The windows are wired through fuse #9 in the fusebox, and there's a relay in the fusebox as well, so either of those could be the problem. The black box under the dash (in the steering column area?) is for the central locking I think. Share this post Link to post Share on other sites

The black box under the dash (in the steering column area?) is for the central locking I think. Deffo not the fuse, shall check the relay but havn't been sure which one it is! I have a black box under the dash, similar to the c/locking but for the windows, according to the markings supplies voltages to both L/R windows so I'm guessing that is the problem. Does anybody have a spare?! Share this post Link to post Share on other sites
Henry Yorke 269 3 Cars Posted October 21, 2008 Sometimes I have to wiggle my electric window realy in the fuse box to get it tot work. I have historically swapped it for another relay and have had the same issue, so maybe the fuse board is slightly worn. It is second relay from the right IIRC Share this post Link to post Share on other sites
Simes 248 2 Cars Posted October 22, 2008 A dodgy switch believe or not can also be the culprit. I removed a passenger window motor assuming that that was the cause only to find it worked. After testing all the wiring back I found that the passenger switch on the drivers side was the problem. Share this post Link to post Share on other sites
RAF_gti 0 Posted October 24, 2008 Well It turns out my little black box is actually one of these http://www.edirectory.co.uk/pf/880/mia/d/a...int/pid/2731999 What is the best way to test the switches/motor? I assume applying +/-12v will make it go up/down? Argh!! Share this post Link to post Share on other sites
pug_ham 241 3 Cars Posted October 24, 2008 What is the best way to test the switches/motor? I assume applying +/-12v will make it go up/down? The switches come apart to clean them out if you're careful. They tend to clog up with fluff & this does quite well stopping them working. The motor can be tested by running 12v to it by removing the switch & bridging the centre pin of the plug to one terminal either side for the motor to run either up or down. Graham.

RAF_gti 0 Posted October 27, 2008 Turns out it was a combination of dodgy wiring, a duff switch and the aftermarket window control box being wonky donky. Thanks for all the suggestions. Steve Share this post Link to post Share on other sites
