Car Has 2 Different Mirror Setups! Do I need just a new mirror glass?

[AudiTurbo]

So, I have been wondering why my drivers side mirror won't work on memory and fold, but my passenger side will.
The first picture is the drivers side. As you can see there are two little connectors (that were not plugged in before I removed the glass today) that are different from the passenger side.
Are the plug ins for the driver side just for heat? (Wonder why they were not hooked up) Where could the plug for the auto dim and memory be? (Can you have them plugged onto the wrong post?

Here is the second picture. I guess it has heated and memory/auto dim since it has another connector? Or are either one of them heated?



Can you even have all three options (Heated, Anti-dazzle and memory?)

[trj]

One of your mirror is heat only.
One is auto dim and heat.

Memory is the the function of the motor behind the glass, so no wires go to the actual mirror itself for the memory purpose.
Power fold is function of another motor on the mirror hinge.

Probably your car's previous owner busted a mirror and replaced it with non auto dim mirror.

Thank you! I know my passenger side mirror has a number 4f0857536c. Do you know what fits the driver side? Also, do other models fit this mirror? Also, since the drivers side memory doesn't even work, wouldn't it be smarter to just change the whole mirror?
Thanks

Trj is saying, the mirror memory feature is independent of the actual mirror used. The memory moved the motor to a preset location. Your mirror can either be heat, or heat and auto dimming. You can do what you want, just know the auto dimming is a ridiculous amount of money, which is probably why the previous owner replaced it without that feature.

ECS has "anti-dazzle" mirror glass, with or without blind spot:

These are all heated:

Thank you for those! Do you all know where the fuse or relay are for the mirrors? I took the drivers side mirror off and hooked a volt meter to it and it's not getting any power to heat the mirrors.

There are different scenarios depending on your need and want.
1. If you want to save money you can replace the mirror only with whatever mirror you want. But it will function just like a basic no autodim mirror.
2. If you want full functionality (autodim, power folding, memory) you will have to do some digging. Whether the PO only changed the mirror(glass only) or the whole mirror assembly, that's anybody guess.

My case:
My car came with no autodim, no power folding, no memory mirrors. I retrofitted everything. Axis has done it too.
There's a lot involved if your car didn't come with those features. But if your car came with autodim, memory and power folding mirrors, then just replace the whole mirror assembly on the driver's with full featured one. You can reuse the mirror cap from your existing mirror.

I am not sure what PO did to your car as you only have two wires connecting to heating elements of the mirror. If it were auto dim, there should two more wires going to the glass.
To know whether the whole assembly you have is memory, autodim and power folding capable, remove the mirror and see the part numbers on the mirror motors. Also remove the door card and see how many wires are going to the mirror from door control module.

It won't get heat just like that.
It only hears up when you run defrosters or heated seats ( I am not sure which one) or it's below certain temperature.
Just like our cars are equipped with heated windshield spray nozzles, they only heat when required.

Your fuse is fine. If everything is working on passenger side there is no reason the fuse is blown.

The manual says when the rear defrost is on the heated mirror (regardless of the temp outside). I turn the car on, turned on the rear defrost and checked that was no power going to the wires for the heating of the drivers side. I didn't check the passenger side, but I guess it's probably the same.
That is why I want to check the fuse or relay, because the folding of the drivers side won't work either. Could it be the knob?
I did get 01734 - Potentiometer for Mirror Adj. Horizontal; Drivers Side and 01736 - Potentiometer for Mirror Adj. Vertical; Drivers Side

As far as I can recall, there is only one fuse for both mirrors. Not sure which one though. I am not home right now so I don't have access to diagrams.
When you say the power folding doesn't work, does it work on the passenger side mirror? Does the memory function work on passenger side mirror?
Also does the mirror control (up down side ways) work on the drive's side with the knob?

I think PO just installed normal base mirror assembly (no power folding, no auto dim mirror, no memory mirror) on the driver's side in your car. Probably someone clipped the mirror and he replaced it with cheapest option available.
And heat not working can be the case of broken wire inside the door panel or not connected at all.
Without removing the door card, you won't see if the connections are messed up. Also, the wiring at the door hinge is a weak link in Audi's. But I assume since the passenger side mirror is working from driver's side controls, the wiring at the hinge should be fine.
There is a slim chance but the mirror adjustment knob can be an issue as well. It may not be making proper contact when you put the knob in driver's side mirror position.

Too many variables.

I suggest, take out the driver's side door card and check for any loose/broken wires and compare the part numbers on mirrors, motors and door control module. Look up memory seats and power folding mirror retrofit. They have very good diagrams for you to reference.
I can take screenshots of wiring diagrams from ELSA WIN if you need.

I would suggest getting Axis's recommendation as well. We both have dug into these wires many times. He might have a different suggestion than I do.

Pretty sure your assumption that the whole housing was replaced without taking into consideration the fact the car had autodiming/folding mirror option is the issue.

Check the fuse box on the driver side if the dash and read the fuse chart to see if the heating mirrors have their own fuse.

The drivers side will let me control the mirror as normal (up and down side to side) The heat does not work and the autodim is not plugged up cause the mirror is wrong (I do need to see if it's getting power at all.
The passenger side mirror does fold when turned to the correct position and the memory works too ( I don't think heat or autodimming works though)

The car did come with memory seats.
There is no heated mirror fuse that I can find. I know on my b5 it was the same fuse as the outside temperature sensor. I wonder if it's on a relay under the dash?

Thank you again for all the help

[trj]

^ I would check what parts exactly you have in the driver's side mirror and buy a mirror assembly or what is required from an a s4 or from memory equipped a4.

[JPT]

I believe that if you in addition to having the defroster on, you have to have the control in the center position (put the joystick in the position that will not move either mirror). A way to tell about power folding mirror housings are the black plastic under the body painted part of the housing.

[AudiTurbo]

I did all of that and nothing still works. No one knows where the fuse/relay is?

[AudiTurbo]

The passenger side will get the 12 volts for just a second when I turn on the rear defrost but then kicks out. Does no one know where the relay is for the mirrors?
Thanks

[AudiTurbo]

So, I went out and looked under the mirrors to find 2 different number stamped on each one. The passenger side was 010681 (Which I looked up is a audi mirror) and the driver side was a 015817 which came up as an Acura mirror? Sometimes the drivers side memory will react to changing when hitting a different memory seat number, but won't always work. Still doesn't fold inward.
I'm lost now. The passenger side would see the volts when I turned it on, but didn't stay on.
What is going on with these mirrors?

[trj]

I do not think there are any relays.
Here is wiring diagram for auto dim, power folding, heated mirrors.









Difference between auto dim and normal heated mirrors.

[AudiTurbo]

Thank you for that, just wish I could find out what my problem is.
So, the auto dim has the surrounding on it?

[trj]

Yes auto dim mirror has black plastic surround.

[AudiTurbo]

So, are the 5 wired connectors the ones that include memory and all the other functions?

[trj]

Your problem is the mirror assembly, I am sure. The whole mirror assembly is from non-power folding base model.
I don't remember how many wires are there in the harness to mirror, but there are more wires for memory and auto dim functions for sure. I can look at the non memory, non auto dim mirror harness later to confirm how many wires are there. But I am not pulling my door card out anytime soon to check how many wires are there in the memory, auto dim equipped mirrors.

[trj]

Take a look at this thread: http://www.audizine.com/forum/showth...etrofit-anyone
Thats my thread when I was doing this retrofit, although its for memory seats and mirrors, there are many links that are very helpful.

[AudiTurbo]

Sometimes when I hit #2 on the memory seat, the drivers side mirror will move some, but not when I hit my setting of #1. So I think it's a memory mirror, it's just throwing the code 01734 - Potentiometer for Mirror Adj. Horizontal; Drivers Side and 01736 - Potentiometer for Mirror Adj. Vertical; Drivers Side
I still can't figure out why either side won't heat up though
