I have to get my 91 State Inspected this month and I thought I had a left turn signal bulb out as the left side would not flash at all. I started to replace the left front bulb - pulled it out of the socket and out of curiousity tried to operate it and it worked....slowly. I re installed the bulb and it continued to blink slowly (the right side signals blink fast). I then cut on the head lights and the left side stopped working. Cut the headlights off and the left signals would again blink slowly - can someone tell me what is going on ....Please ? ?
