Minor and intermitent electrical issue with 1985 911 Cabriolet


Recommended Posts

I've had the car for 4 months now and trying to resolve the few remaining issues - any help is appreciated.

The main/consistent problems are:

1) The clock doesn't work. The fuse is good and the light works, but I can't figure out how to debug it. Is there a way to test the clock? How about the relay which is behind the fuel gauge? Clock has not worked since I got the car.

2) The power passenger sideview mirror doesn't work. When I move the switch to the passenger position and them operate the switch that's suppose to move the mirror, you can hear clicking but no motor whirr and no mirror movement. When switched to the driver’s side, you hear both the clicking and the motor whirr as the mirror moves. Passenger mirror has not worked since I got the car.

3) I can't lock the car (both doors) with the key from the driver’s door (c337cc/Howard already suggested that the problem lies with the micro switch in the driver’s door handle, but I haven't had a chance to look into that yet). It was working when I got the car, it has since stopped since the door stop incident (see below).

The intermittent problems (which when one occurs, they all occur)are:

4) The central locking switch (located in the center console under the A/C fan and temp control knobs) will not lock or unlock the doors.

5) The intermittent wipers don't work.

6) The wipers don't cycle back to the home position - they stop wherever they are when you turn the switch off.

None of these 3 problems appeared to exist when I got the car, but they start showing up (intermittently), when the door stop incident happened (see below). All 3 things are working right this minute, so it's definitely intermittent - and I can't seem to figure out what triggers the problem.

The incident with the door stop was as follows. The original stop had worn out (as they all do) which allowed the door to open too wide. This resulted in some wires being crushed when the door opened all the way (which happened a couple of times). :( When it happened, I heard a clicking sound (like the doors being unlocked) and then I couldn't lock the doors with the key from the driver’s side. I then (purposely) opened the door too wide again (I know - pretty dumb) :eek: and it fixed the problem - I could lock both doors from the driver side again. This happened a couple of more times over the next couple of days/weeks. I figured this wasn't good so I replaced the stop. Since replacing the stop, the doors won't lock at all from the driver’s side and I can no longer open it up too wide to cycle the locks again (something I wouldn't want to do anyway since that's probably not a good thing to do.) :lightbulb:

I'm guessing that there may now be a broken wire (or wires) for both the keylock and sideview mirror switch in the driver’s door. Does anyone know how I can get to them or how to check this?

Also, could there be any relationship between these problems and the intermittent problems?

Finally - how can I figure out what’s wrong with the clock?

:renntech: :thankyou:
