I have a 2002 and for no reason the turn signals and brake lights on the back just flat *** stopped working. the light about the cab works tho but all the turn signals on all four corner dont work along with the blinks on the dash. Im trying to fix it and trouble shot but i've run out of ideas all the fuse and everything work but now im stuck
any help would be greatly appreciated.

 

check ALL your fuses. If they're good then get under the truck and check your wiring. A test light would also come in handy.

 

you might ck the multi-function switch (turn signal high beam ect.)
