Next project is to fix the clock. Anyone know if it can be repaired or replace?
Yes - I think so anyway is this a VDO "Quarz-Zeit" Most of the time these can be fixed by replacing two Capacitors inside the clock. There used to be a link to it but that link seems to have disappeared. I'll try to recap best as I remember (yes I did it in an afternoon and it's still working) - it is also a good chance to change your dashboard light bulbs
1 - You remove the clock from the dash -
1.1 - pry the speedometer cluster out (just pull gently) once you can get your fingers behind the speedometer "unplug" the fiberoptic cables (these light the plastic over the heater controls) then unscrew the speedometer cable - this might be all you need to detach
1.2 there are 2 nuts behind the clock, remove them and push the bolts out - the clock should pop out.
1.3 take the clock inside to work on it.
--- At this point you could put the dash back together and you'd be able to drive the car. But if you can fix the clock in an afternoon leave it apart.
2 - fix the clock
2.1 Your clock is enclosed in a metal case, with a chrome ring surrounding the face. You need to pry up the back of this ring enough so the metal case will slide off (yes this will be impossible to get back to original BUT when it is installed in the dash you cannot see the back just be sure to not hurt the front)
2.2 with the case off you will notice the back of the clock is a circuit board with 2 capacitors on it. Note the size of these, note their orientation (there is a polarity and it is important). Remove them and replace them with new ones.
2.3 you can test it with a 9v battery - then reassemble the clock. Crimp the back of the face ring.
3 - put the clock back in the car (do #1 backwards)
Also the tachometer jumps sometimes until the car warms up.
Not sure about this but maybe a cable wearing out.
