The most recent problem on my 87 Sundance involves the tail lights.
With the running lights off, the rear brake and turn lamps work normally.
With the running lights and/or headlights on, I have the following problems:
- The tail lamps all light up, except when I apply the brakes, in which case the right brake lamp goes out. The high brake light functions normally.
- Turn signals remain solid (no flashing)
The back-up lamps and front running lights/turn lights are unaffected, though one of the backup lights is much brighter than the other, despite both having identical new bulbs installed.
Any thoughts on how to trouble-shoot this electrical gremlin? The fuses are all intact, and the bulbs are all the correct type.
