Typically when car is shut off, the head/tail lights will stay on for a short period of time. Yesterday, they decided to stay on no matter what. I flashed a flash light into the photo sensor and after a few seconds they shut off. Later that day, the same thing happened. I pulled the AUTO HDLPC and AUTO PRK relays from under the hood and now they seem to work as they should, but i have no tail lights. What seems more likely, the sensor being bad or one of the relays?
The turn signal switch may fail causing the hazard/turn signal flasher to continue to click even when the turn signal switch is off. Replacing the faulty turn signal switch will commonly correct this condition.
The passlock sensor in the ignition lock cylinder may fail causing an anti-theft system fault and a no start condition. Our technicians tell us that the ignition lock cylinder should be replace to correct this condition.
