I just did some work on my car, cleaned out the dimmer switch and wiper switch. Dimmer switch is alot brighter now, wiper switch still doesn't work. After I put everything together my blinkers no longer blink. They blink maybe once or twice and that is it. If its a bad flasher it would prolly not blink at all, correct? If so, then its probably a grounding issue. Where do the turn signal's get their ground from?
