As the title states. I have no blown fuses, and all the bulbs are fine. Also, all the dash lights and vanity mirror lights work. Any help?

 

check your wiring, if you have a sunroof, some water might have possible leaked in and corroded the wires. just a thought.

 

Wouldn't that be a b!tch and a half...

Would I have to rip up my ceiling then?

 

dude just pop the covers off and wiggle the lights, i have a stereo in mine and it actaully constantly shakes them out. just a thought, thats what was up with mine when I couldnt figure it out

 

Did that... No dice.

 

Well then its gotta be the wiring. You're going to have to check the wires somehow.

 

mine is like that right now, i took off the fuse the other day and put it back in and it worked, by the time i drove home and open the door, it was off again, i havent gotten time to check on it yet, but i think its the wiring to ...

 

UPDATE:

There's definitely some kind of wiring issue. The +12v line coming into the map light is dead.

I also noticed the courtesy lights on my doors aren't lighting up either. Any tips on where the power lines for those lights meet the lines for the map and dome lights?

 

Door lights are linked to the window switches. if you unplug the switches the courtesy lights stop working.

 

I havent checked but if their is a separate fuse for those lights, put a test light on the fuse and make sure there is power to the fuse box, then check the wiring from there on if you have power at the fuse.

 

BCM behind radio.

 

Yeah its the BCM

 

It's a $900 dealer part. I bought one used for $25. Good as new.

The positive and negative must of touched somewhere.

 

Are there differences in the BCM among model years?

 

Yea, they are different because of features the of the car. Look at the BCM and make sure the numbers on top of it match the new one.

Seriously, I had the same problem and I think it's your BCM. My dome light and door lights wouldn't work. One other thing to check is your key ring light. My didn't work. Change the BCM. It takes three minutes to change.

 

Okay. What's the best way to get at it then?

 

Take the CD Player out. I'm sure you know how to do that. Take top vents out, shifter trim, ash tray, and 4 screws holding the radio brackets in.

It is laying on the bottom and held in by two 10mm nuts. Just look for a black box once you remove the radio/cd player.

 

Cool. Thanks for the help.

What else does that box control?

 

I'm not sure...

 

basically everything.

 

Open the fuse door. At the top is a 7.5A fuse called "Room.L".

Its blown, change it =]

 

No it's something more serious then a fuse...

 

it wasnt when my max did this, or my cousins. it was the same fuse, both times.

 

Eek. So much for taking it out and driving around to junkyards with it for side-by-side comparisons....

 

Didja miss the part of the title of the thread that says "fuses and bulbs are OK"?

 

no, i didnt. My cousin didnt think his were blown either, you could hardly tell. It was a suggestion, if it helps great if not oh friggen well on to the next.

 

I had the same problem. I checked my fuses with a voltmeter and replaced them. The fuses were fine. Actually, the dealer told me the BCM was bad. My dad had it checked.

 

I tested the fuse by switching it and another 7.5A fuse around....

 

I have the same problem but everytime i put another fuse in, it blows.
