Interior lights?

Ok is sounds like you may have a body control module issure. The body control module controls interior and exterior lighting and more. If you have a digital multi meter and would like to do a couple of tests we can determine that. Get back to me.

All you need is a 20 dollar or so digital multi meter. Here is a pic of what you can get so we can do some voltage and ohm's testing ok. Kinda like this one will work just fine. They are trying to sell you a scanner instead.

Yes you can get them at a parts store or home depot or a hardware store. Just make sure it is digital and that it has volts and ohm's and will work on a 12 volt system. Now most meters will not have a 12 volt setting it will be a 20 volt setting. This one has all the setting that we need and more for only about 21 dollars and tax. I hope you can blow it up some and see what I mean. I am not saying you don't understand what I mean I just know that sometimes a pic can clear it all up.

Ok first thing is you need to get access to the lower part of the steering column. On the left side of the column is the body control module. I will include a pic number 3 is the module and 4 is the harness to the module ok. So first I need you to see that the 3 orange wires to the module all have power and they should be hot at all times so the key doesn't need to be on for this. Just to let you know this module controls everything other then the engine electrical. I mean it runs the interior lights it runs the anti theft and door locks, sound system, wipers and washer and A/C and etc. Now get back to me with what you find and we will go from there.

Have you checked fuses? If so, have you checked to see if the blower motor is getting power?

Ther are 2 fuses for the courtesy light they are 2B and 2C on the lower left fuse box. Unless there are loose connections from the the new gage cluster being replaced it would be either a door module or body module out of whack it seems. Unfortunately you need a tech 2 scanner to test these to see what's wrong. They are usually only at dealers.

Recheck all fuses using a test light
check the bulb
any thing else isn't working
if all checked OK need the help of a scanner to test the relays , BCM module and wiring

Have you checked light sockets?

If you remove all light bulbs, will it still blow the fuse? Also, check the owner's manual and see what other accessories are run from the same circuit.

Let me know.

Check the courtesy light switch on the door, If one is broken and making contact and grounding out making the light stay on, also check the dash light dimmer switch to make sure it is off.
