| Courtesy Lights flashing, no interior lights
I have a 92 STS. One of the minor issues I am having is that I have no interior lights. The lights in the door for the door handle works. The light in the glove box works. The courtesy lights in the door locks are working, but these ones come on for a few seconds, then shut off for a few seconds, and then come back on. They do this constantly, even during the day. The interior lights do not come on, even if I turn the knob to turn them on manually. i stuffed myself in the trunk to check the relays and the relay for the courtesy light is working because I can hear it clicking on and off. I've tried switching it out with a different one, but it still just comes on and off...
Any ideas where to start? |
