mirror issue. no tilt!

[jgurnari]

both mirror are panning as they should...side to side, left to right.

When I toggle forward and back to tilt, it pans again!

What is going on?!

I notice on another car similar to mine, on the driver side the wires mirror line up this way:

White( from mirror, to Double white on the harness coming from the car.

Blue comiong from mirror line up to Double black and blue on harness from car.

When I say double, I mean that 1 pin holds 2 wires.


The pass side lines up like this:

white to white...single wires no double

Blue from mirror goes to black on car harness ...no doubles on pass side

Blk from mirror goes to blue from car harness

Striped yellow & red, green and brown are connected to each other. Think brown wires are mirror heating but maybe thats where im gong wrong.

Some issue here on my 84, looking for the solution as well.

Have you dug into it yet?

Do you have one mirror that has with 2w white wires sharing one pin hole and another pin hole sharing a blue and blk wire as well? Like to know what u come up with...

What directions do your mirrors go, or not go,what is the issue?

[76FJ55]

all those wires sound correct. for the early mirrors the system uses on a single motor per mirror and then uses a solenoid to shift a gearbox to change from horizontal to vertical action.
I have attached an image of the wiring for the 85 mirrors, but your should be the same (I assume as
jgurnari didn't mention what year car is having the problem).

so for horizontal the mirror received power and ground via pins 3 and 5 of the switch (+/- or -/+ based on direction of movement). this is working on your car based on your statement of problem..

for vertical motion you will again received power and ground via pins 3 and 5 of the switch (+/- or -/+ based on direction of movement). the power and ground are actually supplied by different internal contacts but again this portion seems to be working. the part that doesn't sound to be functional is the solenoid for vertical operation. the solenoid should be receiving power from pin 6 of the switch to pion 6b of the mirror, and then is grounded via pin 5 of the mirror.

so there are a few possibilities that may be causing this. the internal contacts of the switch could be bad and not providing the power out of the switch. there could be a bad connector for the white wire at the switch or the wire could be damaged between the switch and the left mirror.

FYI on Porsche BROWN is a GROUND wire.

is there a diagram online more legible? very hard to see the print. maybe you can email it? thx

If on computer you can right click and select open on new tab, then zoom in on it.

But if you PM me your email, I can send you a bunch of files.

i have an '85

The problem im have with your explanation is...you mention pin numbers, such as positions 3 and 5, those pins are not necessarily filled with the same color wires as yours, since they have been inserted in different slots and moved around over time. Stating the colors would be the only way to be sure they are lined up with corresponding wires.

also, I attached my mirrors on a friends car and they worked perfectly. I have taken them apart a while ago, and they do have a Clutch that moves an arm to change from panning to tilt. but in my car its not happening. The real difference i see from my car and my friends, is there are pins slots that hold 2 wires. one is 2 white and one has a blue and blk together. My car harness doesnt have 2 white coming from the car. Sorry if my explanation is not easy to follow..this is definitely not my expertise. thanks for your help!

[jgurnari]

i get panning only, no tilt...not matter with direction i toggle the controller

[jgurnari]

The problem is...I do not have 2 white wires coming out of the door on the right side. or left. (white + white)

Ok, I just tried to zoom in on the image I posted, you are right that it is not legible. my copy is very easy to read, but the uploaded image lost that quality. I'd be happy to email you a better copy.

You will not have multiple whites leaving the door. the with wire originates at the switch and goes to the left mirror, where it is paired to a second white wire which leaves the left mirror connection and goes over to the right door, so only 1 white wire coming out of either door.

I see your post of the switch connector color codes. I will have to dig back and see if I can find a picture of a switch with wires (I took some when I removed my door panels). the other option is to use a multi meter to determine what is what by documentation what is connecter with the switch in each position.

OK, found my pic's the colors on the switch directly corelate with the wire colors that are connected to them.

pin numbers by wire color at the switch.
1. SW/VI Black/Violet
2. BR - Brown
3. GN - Green
4. BR - Brown
5. BL - Blue
6. WS - White

To test the switch verify that 1 (Green) has continuity to 6 (White) when the switch is in the vertical adjustment position, both up and down.

Your mirrors are completely different than ours. You have 2 motors, a different switch and different wiring than the early cars.

That is why it as critical that people post the year/model of the car they are working on when asking for technical assistance.

My bad. Sorry about the misinformation

It's all good. Provably a valid reminder that these cars have had innumerable incremental changes, so be diligent with ensuring the data you're using is applicable.

[jgurnari]

thats a lot of wires! definitely different than mine

the diagram is the connector around, and looking at it from the back side ....will see the diagram and wires in the connector will match.

pictured is my mirror motor

Then there are wires from the car harness, green, grey, 2 brown.

With the back of the switch accessible, I would verify that you are receiving power on the white wire when the switch is moved to both the up and down adjustment positions. if this passes then move to the mirror connection. if you do not get power out of the white wire it would indicate a faulty switch.

if you have power out of the white wire at the switch move to the mirror connector and verify that you have power from the white wire with the switch in up or down. if you have power at the white wire, verify that you have a good ground at the brown wire connected to the brown/yellow wire coming from the mirror. if you don't have a good ground on the brown wire, that would imply the ground path is broken or disconnected.

[jgurnari]

where would the brown wire be connected to the yellow/red? i thought the brown wires were only for the mirror glass and didn’t connect to other wires.. only brown to brown. when i did a test with the mirror motor out of the car i got it to tilt without using brown wires… because there are no brown wires on the mirror motors. thanks
