Hi Infini,

Did you get your problem sorted out? If so, how did you resolve it?

I have exactly the same problem, but I don't know where to start! All I've done is disconnected the door switch to have a look at the terminals. Looked fine!

My car is a 03/2004 E46 330Cd M Sport with folding mirrors.

Cheers
Paul.

Sorry mate,

I still haven't been able to solve this problem yet. I will definitely post up a solution if I find one.

So I have an update.. I pulled the passenger side door panel off, peeled back some of the vapor shield and didn't find any modules, just as inifini has found. I also took the mirror off to inspect the ribbon cable, but mine was in good shape -- no visible signs of damage, heat exposure, etc. The mirror started moving after a few minutes, so I know it's getting power, and the motors are working correctly. I guess the next step for me is to get a code reader and figure out what's going on. I hope it's not the main module.. I don't want to think about how much that'd be to replace.. ugh.

My mirrors are going wild, just move randomly whenever they want. Two different BMW guys said it's probably the motors even though that's hard to wrap my head around, considering they move. Apparently the motors are cause of most problems, not switches etc. Probably related to you two?

no I don't think it's related. Your problem is a more common issue which i found when searching for my problem. Other people have resolved your issue by replacing the mirror motor.

If its both mirrors going crazy then i would scan yout codes for errors first just in case it is not the motors causing your problem.

This is my problem exactly. They move totally at will, and I can't control them.

I haven't thought about that before, but need to get my hands on a code reader. They're pretty cheap, so maybe I'll look into just getting one, to prevent future headaches. I've had an indie shop look at it though and determine it was the mirror modules, which is why I ordered the parts in the first place. Knowing they're not in the facelift cars, maybe it could be the mirror motors. Still hope it's not the GM5. If it is, new car time? Maybe. lol

I discovered that the flexible circuit has shorted out between the rubber plug at the door, and the body of the mirror. Apparently effective October 2003, BMW changed the wiring harness to the mirror from a traditional "wire" to a flexible circuit (mine is a three wire supply). Clearly, this very thin material has been pressed so firmly against the metal housing at factory, that the ribbon shape has been embossed on the foam gasket and you can see exactly where the short connected with the edge of the metal housing. I've investigated to confirm that the flexible circuit is not repairable: mirror must be replaced.
Finally some success. I thought there was nothing wrong with my ribbon cable the last time i pulled the door trim off to check. I recently bought a used 2006 passenger mirror off ebay UK and it wasn't until i completely removed my originally mirror, that i could see some damage to the ribbon wire.




The ribbon wire was bent in between the rubber gromet and the mirror housing so i did not see the damage last time. There was also some black crap on the wire which made me think that if the bend didn't do damage, then maybe water got in and shorted the wire out or something.

I installed my the mirror I got off ebay and it is all working again!
Both mirrors work independently of each other and I have the reverse dip function back!

the 2006 ribbon wires are a better design as they are covered by rubber and are not as fragile to bends or water.


Just need to clear out the fault codes now.
I hope this helps out others in the future!

Thanks guys for your input and suggestions.

i've got the infamous hot air blowing from the driver's side (RHD for you people from the US who may stumble on this) and cold air from the passenger side.

About 2 years ago I took to it an air con guy who said there's a leak somewhere and the driver's side vents blow warm air first until all the gas has leaked out then all vents won't be cold. I had it re-gassed knowing it will eventually leak out again. So I took to a my friend who's a mechanic to re-gas, but the system already has enough gas. Being worried abotu over gassing the system, we didn't much to it.

The vents on the driver's side are still much warmer than the passenger side.

I don't know where to start, as from the research I've done on hear, it could be anything!!
I will most likely start with the HCV first since seems like the easiest thing to replace.

I will scan for errors tonight too.

Might be one of the actuators ? Also check if those valves are plugged in an working. Not sure how you would check. INPA will Im sure have some way of checking them. They might be stuck open or something like that.

FYI, the motor & circuit wire is a separate part from the mirror, and can be purchased new from dealership for about $220.00.
