Fuse number 9 (prkinglmps) blows. taillights, dash lights, and parking lights donty work. why? i replaced the fuse 12 times. same ****. went with 30 amp instead of 20 . blown. what the ****? why does it do this?

You have a wire touching to ground (the frame or metal part of the vehicle) somewhere. Do you have a trailer light hook up? If so I'd start there, look for bare wires, or damaged wires. Do you have any broken tail lights or parking lights? Look for bare wires there too, or it could be a bad bulb. Good luck. Don't put a bigger fuse in the system, the wires will burn up. The wires will only handle so many amps if you put in a higher amp fuse the wires will get hot and start the vehicle on fire.

Hello,

This could be a trouble relay, if not a relay, try to observe some other fuses :)
