Map and dome lights aren't working, my radio is working fine. It is aftermarket. Checked all fuses and they are all fine, changed bulbs, and still didn't work, looked at the iod fuse as well, looked at the wiring under fuse box and it looked it fine. Used a voltmeter and there was no power at the bulbs as well as the fuse.

Hi:

This vehicle has a totally integrated power module (TIPM). The TIPM is most likely the issue. The component has multiple connectors which each has multiple pins each. What happens is the pins corrode, break, or just lose contact within the connector and then power is lost to the fuse and component.

If you are not getting power to fuse 17 in the integrated power module, my first suspect is that one of the pins which provides power to that fuse has failed.

I attached a pic of fuse 17 location just to confirm we are on the same page.

Let me know.

Joe
