HI guys newbie here, I need some electrical help. I have a 98 blazer that the flasher/ relay
will not stop. When the turn signals are off the clicking noise continues. As soon as I turn on the
car the noise starts the only time it shuts off is when I step on the brake. Please help.

 

Common problem. Does it change if you hit your hazards (4-ways)?

Most of the time this can be repaired by just replacing the hazard switch in the top of the steering column (it pulls out), but there are cases where the entire multifunction switch needs to be replaced.

 

Anyone possibly have a part number for the hazzard switch ? My 96 does the same thing just worse. My switch broke.

 

When I alluded to this being a "common problem", I guess I should have said that it has been covered in the past. Many other threads link to this thread:
