What owners wrote
I parked my car at work. When I got out of work the car would not start. The low beam lights apparently never shut off. The switches inside the car were all off. I jumped the car and drove home and found that no matter what I did the headlights would not shut off. I went to pull relay 35 and burnt my hand. It was melting and I had to get a pair of pliers to remove it. I have had this relay fail at least 3 times in the past but it never kept the lights on. They would only not turn off.
A couple months ago the low beam headlamps began to randomly and intermittently stop working while the vehicle was in motion. There was no apparent correlation between how long the vehicle had been running and when the lights cut off or how long it would take for them to begin working again. Only hi beams worked consistently. As of this past week, the low beam head lamps are no longer working for any length of time. A local mechanic has been engaged to troubleshoot possible causes.
