Odd turn signal issue.
I have had my '90 735i for almost a month now and I've been having an issue with my turn signals. When I first got the car both blinkers worked right. Gradually the left hand turn signal indicator wasnt working but would kick on the indicator for the brights. Now the right hand turn signal is completely non-functional and the left hand turn signal ONLY kicks on the brights indicator, but the brights do not actually come on, just the indicator. Anybody experienced this before that can help me find the best place to start?
