    Power Mirrors not working.. wierd problem HELP!

    The mirrors did not work at all i changed the fuse and now the driver moved for a second and then stopped - would this be the relay or what? and can anyone point me in the direction of where the power mirror relay would be!
    TIA for any help!

    So I assume the fuse was blown and replacing the fuse made it work for a moment. Did the second fuse blow? Does it still blow a fuse?
    We prefer blowing fuses over and over in a bad circuit to a circuit that quits blowing fuses and ceases to function even for a moment.

    Well blown fuse is a big indicator of an electrical problem ... Duh.
    So was there some work (accident) that might have affected the mirror related wiring to blow the first fuse? Were mirrors knocked loose or something.

    Don't think there ia a relay related to mirrors is there? Anybody?

    same problem. drivers busted but passenger works. weird thing about it is that when i switch to driver side mirror for adjustment, when i move the joystick, i hear the passenger side motor trying to move... normal? i dont know.

    no the fuse didnt blow- actually when i checked the fuse box that one that was in there looked good- but changed it ne ways ... I am not sure of any accident causing this and im pretty sure the mirrors worked when i picked it up and have had no accidents since

    Mine has the exact same problem. Fuse was blown when I got the car, put a fuse in and the passenger side moves fine. When I try the drivers side, the passenger side makes noise like it's trying to move. My first thought is that there may be a common failure mode like something in the mirror adjustment switch that causes a short. Haven't had a chance to troubleshoot mine yet.

    Found the problem...
    Two of the wire terminals going into the mirror motor had fallen out. The two that fell out meant the motor wouldn't work, and if they touched it could blow the fuse. So I'd recommend that anybody with the symptoms above, check the wires going into the mirror motor itself. I plugged mine back in and all seems fine now.

    Sorry to bring back an old thread but I have had my drivers side mirror not be able to move since I picked up the car didnt really bother since I just manually moved the mirror to my perfect position. I now want to take care of it. Iam going to check the fuse first but if that doesnt work are the mirror wires behind the door panel or do you have to remove the mirror it self to check these wires. My condtion is exactly like the guy that was having his passenger motor move when the I had the switch to move the drivers mirror.

    And one last question can you post the proper fuse to change thanks

    Pull/snap the mirror glass out straight out of the mirror housing to reveal the axis motors and the motor wiring. You will likely find that the wire connectors and terminal plugs are corroded if not just dirty. Take them all off and clean with a red ScotchBrite pad and some electrical contact cleaner and put them all back together. The mirror snaps out and back in like Lego—it's pretty simple once you see how it assembles.

    The mirrors and the wiring are exposed to the outside elements for the most part and can take some abuse over time. Cleaning the wires and terminals in the mirrors is easy and fast, and likely the source of your problems.

    Good luck,

    Ok doug thanks allot I will try that and report back. Since Iam going to check the fuse first do you know which number it is. And why would the passenger motor be moving when I have the switch turned on to the drivers side thats the part I dont understand.

    The fuse wouldn't be something I would look at. It either will work or it won't with a fuse (not blown or blown). Sounds like either the wiring is backwards somewhere--likely at the door switch--or there could be a short somewhere. Get both mirrors working first, then track down the cause of the reversed mirrors. The switch may have just been put back in the door card upside down, too. It could just be a matter of reversing the wires plugged into the back of the switch or flipping it around in the door.

    It would be one fuse for all mirrors. On my car it is fuse #24 and is a 10A fuse. If one mirror works, it's definitely NOT the fuse.

    OK yeah you answered my question about the fuse right there I thought each one had individual fuses

    Hmmm, I'll have to try this out as well. Ever since I picked up the car 2.5yrs ago the driver side mirror works fine (though very loud and slow) and the passenger one hasn't worked at all. Snapped it into the right position but has always bugged me. Now to just narrow down that airbag light.

    So I went out at lunch and recorded a quick little video of the simple removal of a mirror glass to access the motor and wiring. This stuff is all exposed to the elements, and on a car this age, the contacts can easily become a mess. IF your mirrors work intermittently, or one works without the other (or if one moves up when you push down and left when you push right), your motor contacts might be a mess.

    [ame]http://youtu.be/_wp_yJDg7b8[/ame]

    Take the mirror glass off, clean the prongs and wire connectors with electric cleaner and a small 3M ScotchBrite pad, then lightly re-crimp the connectors so that they hold tight on the post. Test the motors before putting the mirror back on to make sure things are working.

    It's possible the electric motor in the mirror has failed, but honestly it isn't likely. Brush or comm wear in one of those should be minimal to nothing. The odds are it is not working because of a bad connection and can easily be rectified with a few minutes of labor.


    Good luck with the troubleshooting.

    Thanks, my car is fairly stock—K&N drop-in air filter, CD43 head unit, ZHP shift knob, VSL aluminum radiator, Stewart water pump. I'm just chugging through a list of things to repair or replace before I start doing anything to the car for any performance upgrade. Click on my sig image for a lame-o and verbose blog that tracks anything that I have done to the car since I got it.

    Badass I just read your blog on the Stewert Water pump and aluminum housing I want to look into see if they sell a electic which is amazing since you can have the car sitting in the racing dock or just sitting anywhere and have the pump cooling the block constantly but if they dont make one I will look into buying the stewrt one. Iam really am surprised about BMW allowing these cooling very essential parts to be made in plastic.
