Need Help Asap!!! - BMW Forum

alright, so my new taillights came today and i was installing them without a problem. got them in and was checking to make sure all the lights were functioning properly. one light wasnt working so i was playing with it and then there was a spark, like a metal to metal spark of something shorting out. as it turns out now the brake light, tail lamps, front parking light, and drivers window doesnt work at all. the passenger side lights all work fine, as do the passenger windows and rear drivers side window, and so do the front turn signal and fog light and headlight, and the rear turn signal and reverse light. i am very confused and i need to fix this ASAP. i need help!!!

Have you checked the fuse panel yet?

92_325i · 08-04-2005, 05:30 PM

yes. i'm not that stupid. i even replaced every fuse i could with new ones to see if that solved anything. but i was looking for something along the lines of a relay to check or something in the wiring and such.

Okay...

Another culprit for you could be the comfort relay. This could be the cause of your window problems.... Finding the comfort relay

You said you heard a pop. Did you see (or smell) anything odd after that?

92_325i · 08-04-2005, 05:39 PM

i know about the comfort relay. that isnt the problem. only the drivers window doesnt work. the other three work just fine. and this didnt begin happening until the issue with the taillight. and i said there was a spark. i never said anything about hearing a pop or anything along those lines. there was a spark like you would see if something just shorted out. it took out the drivers window, the drivers side taillights, drivers side brake light, and front drivers side parking light. everything else works properly.

alright, so now both brake lights work properly. the one window, drivers front corner light, and drivers side taillights dont work still. anyone have any ideas??

This happened to me when changing the license plate light. For me it was only a blown fuse. THe tailights run off seperate fuses (so if one blows you still have one working taillight). Various other stuff didnt work as well. You kind of took offense when checking the fuses was suggested, but i suggest you take your time and really look at them

92_325i · 08-05-2005, 09:56 AM

the fuses have been checked multiple times. they have all been replaced as well. every one of them.

93 325i · 08-05-2005, 11:42 AM

hmmm.. so driverside front corner, tail, and window dont work. Fuses are checked and rechecked.. were any of the fuses blown? Cuz i have an A/c problem that reverts to a fuse. I found the blown fuse replaced it and the A/C still doesnt work.. Rechecked the fuse and it is blown again. A short keeps popping the same fuse. Mayeb the tails are shorting the fuse over and over again.. This all reverts to the tails since it happened when installing them. Check those over real close, possibly dissconnect them and test again.. this seems to be a hands on kind of problem to fix

92_325i · 08-05-2005, 11:50 AM

i have disconnected the battery, rechecked the fuses, and replaced the fuses i already replaced. the only blown fuse i had originally was for the A/C which doesnt even have a belt on it right now. i guess i'm going to try to hook the stock tail back on and see if that helps anything. any other suggestions are welcome.

92_325i · 08-05-2005, 12:27 PM

alright, so putting the stock tails back on didnt solve anything either. i am out of ideas unless someone knows of a relay i should be checking or something.

93 325i · 08-05-2005, 01:25 PM

if you can sit tight i will check my bentley after work or if someone else can help.. i was just looking over the wiring diagrams for fuses and relays and such and they are an excellent guide..

92_325i · 08-05-2005, 02:03 PM

that would be awesome. i just dont want to drive too much in the dark if they arent working. the last thing i need is to get pulled over.

Hey i dont want to scare you, but if have replaced all fuses, checked everything that it shuld be checked and nothing works, i will tell you that most likely you have fried some wires on the car. Be ready to start puling some plastics to check the harness, and by this i mean checking each wire to make sure they didnt melt the insulation or damaged somehting else.

anyway let us know what you have found.

Dudesky_E36 · 08-05-2005, 06:30 PM

Okay . . entertain me here. I know this is weird, but check for chafing in the wiring harnesses by the tail lights and the ones in the trunk lid.
