Door Mirror Switch
Discussion
I've been doing a few things with my driver's door (re-alignment and turning some switches the right way round after the car was trimmed) I've reconnected all the wires as per my diagram before disconnection and I have the following problem.:- when I try to adjust the mirror in the up or down position I just get a tick sound. This happens in both nearside, offside and middle positions of the mirror selector switch. Left and right are fine. The tick sound appears to come from within the drivers door. Any suggestions greatly received. Cheers. Just thought, I did'nt test the mirrors before I disconnected so the problem may not be related to the disturbance.

There is a relay in the driver's door to do with the mirrors, usually just dropped in or sometimes tied to the door frame. I can't remember the exact function but I would try another one, with a bit of luck "SPEND" will be along to explain it properly.
I don't know a great deal about how relays work but do you know if I can 'borrow' one from a different circuit for the purposes of illimination?Cheers
That relay is real PITA to access, you can check its working from the mirror connector.
You should see +12v switch between the Lt Green and Red/Blue terminals when the relay clicks doing up or left IIRC (otherwise its 0V and down or right give the 12V.) If you don't see it switching make sure the switch itself is doing the polarity inversion - the relay just swaps it between motor 1 & motor 2.
Easy enough if you can read the wiring diagram in the bible, sorry but all my documentation is about the later mirrors.

Any idea where in the door it is? Thanks for all the info do I need to just put the red probe on Lt Green and the black on Red Blue, put the meter in 12v and operate the up switch and the meter should read 12v? The left and right work ok?

Its further back than the most awkward bolt 
and up a bit generally.
In the mirror are 2 motors, 1 up/down, 1 L/R. The controls supply +/- to move them one direction and -/+ the other. This reversing of polarity is half done in the switch and half in the relay IIRC. This is because the switch was designed for mirrors with clutches & motors so the adaptation just makes it a little bit of a logic test. 30mins studying the wiring diagram is necessary however much explanation you can be given ~ fault diagnosis / tracing requires a clear understanding and cannot just be prescribed willy nilly

So what you're saying is, if a replacement relay doesn't fix it then it's back to the dealer. No worries. Cheers and up a bit generally.In the mirror are 2 motors, 1 up/down, 1 L/R.

Not wanting to highjack the thread but I dont suppose anyone knows where I can get one of the pyramid shaped mirror adjuster switches from?
I've got one spare, came from Bell Hill last month. It didn't fix my problem where my passenger mirror goes up and down but not side to side, gave up and just move it manually now.
ks! Anyone got any other ideas?fog66 said:
Did you change the relay in the door or just change the pyramid switch?
Phil, just the switch, I was following advice on another thread which didn't mention the relay. As it's side to side I've just manually adjusted it for now and moved onto other things, as yours is up and down it won't be as easy to do this I suppose.AlRaven said:

Thanks for the update, it's all good info to have. I'm attacking the job with a mate on the weekend so we will see if we can track the problem down. It'll probably end up being some weird inline fuse in the door or a loose or broken wire somewhere.I'm pretty sure it isn't a problem with the joystick or the mirror selector switch or the relay and I'm pretty sure both motors won;t be faulty at the same time.Cheers
I have a similar problem fog66. I removed my door card to fix the Cig Lighter' wanting to use the socket for my sat nav (Ended up running a new fused supply from the battery!)Anyway on re-assembly with my crappy diagram of the switch wiring I now have a similar problem to you. No left or right movement of the mirrors. I've put this down to incorrect replacement of the switch wires. I've tried various commbinations on the switch but can't seem to get full control of each mirror. I thought it might be the 'Joy Stick' switch but on removing the door card again!! )I'm getting good at it now, thanks to fitting wing nuts!)found that the switch is a moulded plug. So I will watch your developing post with interest for a successful conclusion. Doesn't help when you're partially Colour Blind either! Cheers John042

JohnCan't say I share your enthusiastic optimism of a successful conclusion however I will be doing my best. It's interesting that we both have removed the switches which we thought were working prior to being 'fiddled' with and now they don't work in one direction on both mirrors. Perhaps you're right and it's just a mismatch on the way the switch has been re-assembled. I'm all for looking at the most obvious thing first. Cheers Phil.
