The motor was not designed to be replaced. Since you have an 85 like I do, your mirrow will pry right off. The photo two up, with my hand holding the mirror show the 4 rivets that have to be drilled up to get to the motor. I have never done that, as mine works.

I have had my 911 27 years, and I am pretty much the only driver. I only need to adjust the mirrors if I bump their position as I am washing the car. The motors all work, but once they are "set" I never adjust them. I do have a wide angle curved mirror on my passenger side so objects are closer than they appear. I just want to know what is there, and I can figure out how close with a turn of my head.

Good luck with the motor swap. Let us know how it goes.

i just noticed!… if I toggle the switch for horizontal on the pass side mirror which does not tilt, BUT if I toggle the switch for tilt it moves the horizontal as well. does that mean it’s more likely wiring than the motor?

jgurnari 07-15-2022 09:04 AM
this is interesting…
when i try to tilt the pass side mirror, the one that does not tilt, i hear a clicking inside the drivers side mirror. but when i pan the pass side I do not hear any clicking coming from the driver side mirror. ????

do you have a photo of which wires go where in that switch?

Check the continuity of the 4-way switch on the door. You may find that there is one axis without.

You should be able to remove the bottom cap by gently parting it from the main switch body; the two silver "rivits" will unwind out. Then it's an easy case of cleaning the contacts.

You should get something like this. Once it's clean and properly lubricated it should work again. Fixed mine that way.

Unfortunately, I do not appear to have a photo on hand, however, the part comes with a wire color code graphic (at least that is what I think it is), which can be seen below:

not clicking
 
i bought 2 new used mirrors… what’s happening now is, when i move the directional horizontal mirrors moved horizontally as they should, but when i push the switch to move mirrors vertically the mirror again move horizontally.

If it is clicking, then the switch isn't the issue, it would be the gear-set or control wire that moves the mirror. (The adjuster motor is in the mirror body, and it's not an easy fix from what I have read in other threads here).

The position switch has three pins that reside in the upper switch body and make contact with three cones. The lever moves the pins into the cones and the cones rock to the side to contact the plates the wires connect to. All it takes is for one of those things to be dirty or not set properly and the adjuster won't receive its signal. All mine had was a little mfg grease between the cone and the plate that was causing an electrical isolation issue.

There is also the side of the car switch on the dash. Not likely to cause only one functional direction loss, but this is Porsche electrics, and they are funky to begin with.

how did you get pins out?
 
how did you manage to get the rivets out to open it up?

The rivets will work their way out when you work a thin blade between the main body and the piece in the top right in the photo above. A narrow, thin flat blade may also get under the rivets.

got it apart but...
 
OK, got it apart! what "cleaning" is needed? I see it has grease.



Thanks for your help

The thin end of the pins go into the springs, and the fat end into the conical cups.

I found the grease was my problem. After I cleaned most of it away - I left a little for the pin/cone interface, and a little for the other end of the cones in the small housing where they articulate - the contacts to the side plates was more direct. I'm sure the grease is there by design, but there was no other path of resistance that I saw in mine - no carbon build up, no wear marks, just aged, waxy grease.

BTW, I did have the switch out of the door before, so it wasn't the electrical connection there.

jgurnari 08-21-2022 06:14 AM
Great ... I did the same, I removed the excess grease. Hope it work! Thanks for your help

Do Brown wires have to be connected into the back of the mirrors for the mirror to tilt / pan properly?

Could THIS be the reason my mirrors move horizontally and AGAIN move horizontally when I move switch to tilt mirrors?!

Dont see how the brown wires would make a difference.

917_Langheck 08-21-2022 11:01 AM
Pretty sure brown is ground for the switch as it is elsewhere. So long as both switch and mirror are grounded the switch should work.

jgurnari 08-21-2022 12:28 PM
tried this.. i don’t have brown wire except..
 
except i have brown wires for heating mirror’s … we connected the yellow striped to power and white to ground got a click buy no movement. i can get it to pan but not tilt in any combination of wires. could it be thAt all FOUR mirrors have the same issue?! seems the odds are against it. the person who sold me the 2 last week swears he tested them for tilt and pan … do you have a schematic available?

I hear a click
 
I hear a click when I used the yellow striped wire on power and the white on as ground, other than that it only goes in the horizontal direction.
...and please check other photo, does it look right?

its apart..think its the magnet clutch, not moving when tested on 12v transformer. or diode failure...????

1 question about your disassembled mirror
 
your post was so very helpful! i did take mine apart as well and think the problem is with the diodes. found one diode was broken. can you tell me which direction the diode is connected, white or yellow wire? or have a close up picture of the diode so i can see which end is connect to the white and yellow wires. The diode has a band printed on it, that will tell me which end goes where and to which wire. my photo below is after i soldered it on, want to be sure it’s on correctly. you can see the band on diode is on the white wire side. not sure that’s correct… like to verify. thanks
