strange interior dome light issue at startup
strange interior dome light issue at startup
When I first crank my car, my dome light flashed for 3 cycles at 50 flashes per cycle (that's a total of 150 flashes, just to be clear). I hear and feel a clicking under the dash that coincides with the flashing light. It isn't the turn signal or hazard lights. Those have a different sound and pattern. Even if I turn off the dome light, the clicking under the dash still goes follows the same pattern. It never starts while driving, only when I first start it. I have started it with the parking brake off and on, park and neutral, door open and closed...just to try to narrow it down. I have looked at the electrical diagram and checked the fuses (inside and under the hood), but all applicable fuses are fine. I have a check engine light because of a knock sensor that I am replacing this week, but no other warning lights.
Any ideas on what this could be?

Re: strange interior dome light issue at startup
is the car stock? clicking is almost always a relay gone bad. im not sure where it would be tho. try and see if you can hear it and discover the place. im guessing the fuse box area under the dash.
Re: strange interior dome light issue at startup
everything in the car is stock right now. no aftermarket electronics or engine parts of any kind. How do I test a relay? The sound/vibration is coming from under the dash to the left of the steering column, so the fuse box is a likely place. I just find it odd that it would trigger the dome light.

Re: strange interior dome light issue at startup
see if you can find it and replace it. they are easier to replace. altho, you can try opening it up and see if there are any loose solder joints and fix them.

Re: strange interior dome light issue at startup
Sounds like a low battery to me, voltage drops low enough during cranking for things to start going crazy.
Charge the battery before trying. See if it still happens.
Check the level of fluid in the cells.

one additional tidbit, if I turn the key (regardless of whether I start the car or not) it will start clicking. When I turn the key off, it will still continue to click.

Re: strange interior dome light issue at startup
did you have the battery tested as suggested? low voltage is almost always the cause of clicking relays.
Re: strange interior dome light issue at startup
I had the battery tested and it was fine. The guy who tested it also said a bad relay. I just have to figure out which one.
is it possibly a relay that is somewhere in line with the ignition switch? I was wondering if that might help narrow it down on the electrical schematics.

Re: strange interior dome light issue at startup
Locate which relay is doing the clicking. Some in the under dash fuse box and some behind the glove box. If you touch the plastic case you should be able to feel which one is clicking.
If the dome light is on, does it still flash following the relay noise ??
Knowing which relay may help.
