Electrical issues

[Passport]

I have a 99 Tahoe with 75,000 miles on it that is starting to have some issues. First my dome lights would not shut off all the time after closing the doors, Im thinking dirty/worn contact. Didn't have time to chase it down so I have been using the dome over ride button. Now my blinkers and backup lights are not working, keeps blowing the fuse.

Any ideas what might be causing this? Im hunting a bunch and just dont have time to chase this and hate he thought of taking it to the dealer and getting my head knocked off.

thanks

What style rear doors do you have? Probably a bad door switch.

Check the wiring for the towing.... Check MFS.....

Dutch doors, replaces the switch there manly cuz it was easy. What is the MFS?

MultiFunction Switch..... turnsignal one... Unplug it and see if fuse pops...
