What else happens ?

Dash lights on ?

Any warning before it cuts out ?

Same failure mode as mine then

Glad you got it sorted, that switch wiring & how it works still seems to be a bit of a mystery


Mirrors sorted - switch needed cleaning
Tracking & steering wheel centre sorted - was set to parallel, I felt it was a bit off on the drive home last night on a country road
P1110 was because one of the connections to the boost control valve was off. Mair now matching Mreq up from 960 to 1160 as well  :Fawlty:

Aircon place was closed this morning, so that'll probably take some time, satnav date looks like a Tech II solution. Let's hope I don't have to disconnect the battery

SID tells me I'm getting 33 mpg, which I expect is OK. DTE & maths suggests similar

That all makes perfect sense

Good idea splitting this topic off, seems like it will be turning into a reference thread  :thumbsup:

I sort of understand, but remain confused  ;D

Where I got to was as follows, for the drivers side:

Motors have connection to the switch, two connections per terminal
Power is supplied by either physical movement of the switch closing a set of contacts, OR
Direct from the PMM module,because of seat switches

I have no idea how the PMM module / seat switches know the position of the mirror motors..... but haven't looked properly either

You should be able to see 12v at pin 2, 4 or 5 without removing the connectors

Interesting you see pin 5 as a common feed. It is, but I come from a common earth mentality. Makes little difference in this case, apart from testing

Oh, and if you disconnect the door connector with the ignition off, how does the door sensor know that you ever switched the ignition on (if a code is thrown you can clear it anyway I assume)

Thanks !

Your wishes worked, plugged it back in and both mirrors working correctly.

Just a build up of grunge, probably partly attributed to a period of non use

Good luck with yours

Away from home, limited resources...

I used the probes from the DMM to separate the two halves of the switch. Rubbed the edge of a cotton towel over the contact section & it came away with a brownish smudge.

Reassembled & I now have continuity between 1 & 6 (revering dip) and 1 & 4 on the ball. I'll refit it tomorrow morning, fingers crossed

Sluggish mirrors when engine off are perhaps indicative of a feed / earth problem

13.6/12.6 volts should probably not be noticeable, but 13.6 / 10v for example will be

I am unable to get any continuity on my door switch. I could dismantle it, but should probably just bang another one on as a quick test at the weekend

Pin 1, usual Saab black,  is earth, try a continuity test on that

Just an update on mine, in case it helps

Manually moved the mirrors & memorised the seat position

The mirrors move with the seat position so I have the ex 1991 Cavalier mirror switch to try & test the electrical connection

Might be worth just dumping some contact spray in & wiggling vigourously  ;)

IIRC the drivers mirror does not use the PMM for either feed or earth, will need to study that complicated wiring diagram again

So, test drive was 100 miles at 7:00 yesterday morning

She drives well, nice & tight, no major issues, the niggles:

Electric mirrors not adjusting (hmm, who else has this problem at the moment)
Aircon not working, probably needs regassing
Steering wheel a bit off centre, so tracking to be redone to both sides
Chucked a P1110 code, so I need to check the boost control valve pipework

& finally

The satnav time is fine, but is showing a date in 2001. Do I really have to use Tech II to adjust this. I discovered the orginal Kenwood cannot get the time from RDS but as I understand it the later satnav used GPS for the time, which surely has the date information as well?

I just had a look at the wiring diagram

Because you said both sides stopped working at the same time (& IIRC you have PMM) I went looking for a common part of the circuit. The only bit I could see was the PMM module. I don't know how the Tech II gets the voltage message, if it's the i-bus, then perhaps the PMM is getting the signal to provide voltage to the mirrors but failing to provide the output ???

Oooh, that's sort of good news for me

Both mirriors are free to move by hand on the black car, but only move about 1cm before stopping. I'll be interested in he resolution

She's ready for the road now, to be taxed from Tuesday & will become another daily (I hope)

Will probably never be this clean again ;D

Tech II's are good diagnostic units in the right hands

Lots of deep menus though

Glad you got it sorted

Now there's a coincidence

I have had a little issue with the green car recently. It's been going occasionally into limp mode (error 15 on Opensid) and not into limp mode with error 10

DTC's seen were 1251 & sometimes 1231

Working through the DI & plugs I noticed the engine was hunting a little on idle & thanks to a borrowed Tech 2 I saw some misfires across all cylinders. Opensid error 10 came back a few times, but performance was unaffected & the limp mode was not activated. Finally P1231 popped up again.

WIS said it was a problem on the potentiometer in the throttle body. TB swapped, no misfires, no limp mode errors on opensid.

Strange things aren't they sometimes

I drove home & the car was running smooth again, especially when transitioning from overrun to producing a little power again
