Preventive In Dash Repairs On 1986 560 SEC

1986 560 SEC coupe

Greetings:

I share Kent's pholosophy of prevention. I have removed the center console where the shifter is and the radio, climate console and ashtray to refinish the wood. While all that is out, what things do you recommend that I change out while I have easier access inside the dash? BTW I am in the process of replacing the climate control motor brushes and the gauge cluster lights as Kent suggested but was wondering if there were other items?

Thanks,

John Sebastian

Missing Vac Switch in ALDA line.

I have a 1979 W116 300SD, chassis has 334k miles and rebuilt engine around 100k. When I purchased the car, the vac switch that attaches to the firewall that helps control the ALDA valve is missing. I have read various articles describing the pro and cons. I am afraid to 'step' on it in fear of what may happen. Should I replace the switch? Or what would you do?

1985 w126 300sd cental locking system failure to lock

I have posted this question on a few other Mercedes Forums with no assistance. So...I have paid the 30 bucks for hopefully some light to be shed.

I have a strange problem with my central locks.

The problem I am having is that locking any controlling (driver passenger trunk)lock will cause all locks to unlock but it is impossible to lock the doors. I obviously have no leaks.

What I have so far.
I have run the pump on the bench and if I ground any of the 3 pins the pump pulls untill the vac switch makes. Then if I apply 12v to a pin the pump pushes until the press switch makes. This seems to make sense. Keep in mind I did not test the pump with a constant 12v on any pins and I will try that later today.

I also tested the wiring in the car and all is correct.
