1988 325-RF turn signal intermittant. Changed bulb, cleaned all contacts-will work for 30 seconds then quits. Rear lights flash rapidly with front out-OK with front working. Emergency flashers don't work. Will bad flasher switch cause this problem only on 1 side? Left works fine. Also, where is chasis ground for turn signal-above brake pedal?
Other issue-warning lights in overhead for licence plate and rear loghts come on often with lights working fine. Is the sensor in the trunk for these?
