1997 Chevy Blazer Blinker Problems

Greetings everyone,

My 97 4x4 Blazer was having some strange problems with the turn
signals. For a while, sometimes the blinkers would work, sometimes
they didnt. Now they have just stopped blinking completely.

The hazards do work fine. The lights flash and you can hear the
blinking sounds. When you push the turn signal lever up or down, you
get no lights and no sound (inside or out). The springs still seem to
work because after you make the turn, the lever pops back into
position.

I would like to tackle this myself, but before I do I was wondering if
someone could help me narrow down my search for the problem. The fuses
all seem to be OK, which leads me to believe that I will need to
replace the multiswitch. This is an expensive part and was wondering
if anyone knows of anything else I can check before make the purchase.

Thanks for all your help,

Ben M.

I would swap flashers with the emergency flasher first to see if it is
just a failed flasher.

On most makes there are two flasher units, one for the hazards and
one for the turn signals. Most of the time they are together on the
fuse block but I have seen some in a separate place, like mounted on a
clip on the underside lip of the dash near the steering column....don't
ask me why.

But before you go and replace the switch look for the weak link first
and and make sure you get the right flasher for the truck, otherwise
you could get some weird flashing rates

Check all the bulbs first. A broken filament can cause all sorts of bizarre
turn signal behavior. If all the filaments are good in the bulbs I would
move on to suspect the flasher unit. There are two, one for the turn signals
and one for the hazard lights, switch them around for a quick and cheap
test.

Since you describe both the left and the right turn signals are not
functioning I would also suspect the multifunction switch or possibly the
hazard switch in the steering column.

I am sure someone will correct me if I am wrong but I believe that era of
Blazer has issues with the multifunction switch or the hazard switch
malfunctioning and causing all of the brake lights but the CHMSL (Center
High Mounted Stop Lamp) to not function. I know I have seen MANY like this
on the road, in traffic.
