Ok so I only checked the “light” fuses, so you suggest looking at everyone of them? I don’t mind just wanna make sure. I will buy a switch but since after BYU g the clock bulb and no success I kinda feel like I don’t wanna make things worse, eventhough I apparently did since now the lights don’t work.
I just can’t think of anything else it should be especially when there really is only 2 fuses that have to do with the lights. By the way the map dome lights work when pushed but the other lights throughout don’t when we open the doors nor when I tried to manually turn them on...so frustrating and I feel defeated..seemed to have made things worse.
First off, don't be discouraged. We've all been there so many times. A couple weeks ago, I had two of those in the same day. It was very discouraging, but taking a break and coming back the next day with a clear head, I was able to successfully tackle them. I think many people on this forum would echo, that we've learned the most after failing first.
Secondly, I wasn't able to find a wiring schematic for the 2003, but I'm going to go out on a limb and guess that it's pretty similar to the 2007 schematic in the 4th post of this thread:
Has anyone had this issue: The dome light on the drivers side will not come on when any of the doors are open. All of the other lights (passenger front, 2nd row, 3 row, gauges and doors come on. Here's the weird part - it will turn on when you manually switch it on the lens itself. I thought...
I'll work under that assumption, but if anyone has a schematic for the 2003 that says otherwise, please post!
When troubleshooting electrical problems, the two most basic questions are: 1) is there power coming in? and 2) is there a place for it to go (ground)?
The fuses would be the most likely to keep power from coming in; doesn't hurt to check them, but the fact that the front dome lights come on when you press them means that the fuses are good, and you have power coming in. You can corroborate this by pulling one of the bulbs in the rear and checking for 12V against a known-good ground.
So that means that something is keeping the current from having a place to go; i.e. the issue is on the ground side of the circuit (the bottom half of the referenced schematic). The driver/passenger dome lights have their own chassis ground (via a mounting screw that goes up into the steel ceiling). All the other lights are grounded through the dash switch. In the "ON" position, they are grounded directly. In the "DOOR" position, they are grounded through the "MICU" controller when the doors open.
Since they don't work in either the ON or DOOR positions, I would agree with egads that the dash switch may well be the culprit. Not sure how much that switch will cost, but if you want to confirm before purchasing, you'd need to start by unplugging the switch and checking for a solid ground at pin 5 in the harness connector (be very careful not to spread the sockets when probing).
Another (easier) test you can do is: 1) put the dash switch in the ON position, 2) press the driver dome light - is it on or off? 3) press the driver dome light again - is it on or off?
If it is on in steps 2 and 3, the ground at pin 5 is good. If it is off in either step 2 or 3, either the switch is bad or there is no ground at pin 5 (switch would be most likely).
Hope this helps point you in the right direction!
