I have a 2001 S10 Blazer 4WD.


My issue is the driver brake light will not work, neither does the back up light. The turn signal does work, but heres the kicker....the driver brake light will work when the passenger turn signal comes on. all other lights work except for the driver side. Ive checked all fuses and light bulbs, any help would be awesome, thanks.

 

Bad ground on the driver side.

Remove the driver side tail light housing.
Remove all 3 bulbs from their sockets.
Check the resistance from the ground terminal in each socket, to ground.
Post the results.

 

Its a bad turn signal switch/lever assembly. I had the same thing happen to me and this fixed it. You can find them on amazon for a pretty good deal.
