on my f150 my abs light turns off after start up then turns back on in about 5 seconds then stays on constantly, i have no break lights, third brake light or turn signals. this all started as soon as i took out the the flasher under the dash to borrow it so i could ride my motorcycle. i have no blown fuses.
any help is much appreciated thanks.

 

put the flasher back in and see what it dose.

yes, the first thing i did was put the flasher back in, ive replaced the bulbs in the tail lights, ive checked every fuse and relay on the truck, i put a new ground from the battery to the engine and the abs light goes off now but i still have no brake lights or turn signals, i have tail lights when the headlights are on. i would really appreciate the help as soon as possable as this being my daily driver.

 

i had a stupid moment, well, actually my whole day was a stupid moment. my hazzards were switched on and they havent worked since i bought the truck. and it wasnt allowing the brake lights or the turn signals to work.

 

funny you mention that. i just had that happen yesterday. hazzards were clicked on but were not flashing. had a friend pull me over and tell me my brake lights weren't working

 

The hazard flasher is hidden on the BACK of the fuse block, directly behind the turn flasher, and it's a PITA to install correctly because you can't see the terminals as you're stabbing it in.
