Today I finally fixed the light inside the car 1982 300 SD at the instrument cluster and also removed the radio and ash tray.....when I put all back (by the way I just use sand paper on the reostat spring and like magic lights came on after 3 hours of guessing and testing a lot of wires), well now I have a lighted instrument cluster and I can see if I am in park or reverse at night and check my speed, temp, etc.
But the vacuum lock that used to work fine before the fixing of the lights is not working anymore, any body with the same problem?
Did I disconnect or break a vacuum hose pushing back something?
Any help will be greatly appreciated
