HELP!!!

[Will Carlson]

Parking lights no longer flash when locked and unlocked, fog lights don’t work, and door switches don’t light up!! Is it a fuse?

you could check all the fuses but more important is to check the battery cables and grounds even if they "look" ok take them off clean with a wire brush and tighten them back up and see if anything changes. then once that has been eliminated proceed to checking other things, poor ground and power connections make these trucks do goofy things

Your posting an electrical problem and haven't checked all your fuses under hood and side of dash really??

As @Doubeleive and @corvette744 said, basics first and make sure you check them thoroughly. Or you may need to search and take care of all the points:

Pro tip for any problem solving scenario before turning to the internet: If you suspect an easy way to check, do it. Then post if you were successful or not so others can learn.

Look up fuse locations, disconnect battery. If that doesn't work then post again. It will be much easier for the awesome folks here (best automotive forum on the internet) to narrow down issues.

People here are totally willing to help.

EDIT: Oh, and if pulling fuses or disconnecting batteries are not something you're familiar with, say so. You'll get help then too.
