I bought my '89 Comanche used and the turn signals didn't work.
I took the Steering column apart and replaced the turn signal switch.
It is a standard GM part. $30
was not the problem - cause it STILL didn't work.
I gave up and went to an "Automotive Electrical Repair" place
and they found that a wire inside the Fuse Box
was burned out
There is NO WAY that I could have fingered that out myself !
So they tapped into a hot wire and inserted a Line Fuse and powered
my turn signals with that. $85
When I asked why that would have happened - ????
They speculated that maybe the previous owner shorted it out putting
Trailer Wiring in - has a bumper hitch.
The trailer hitch wiring was all BOOGERED up ! Smashed and repaired
what looked like many times....(?)
Electrical repairs are a Bastard if you can't see well and can't stoop
and work under the dash and don't know which wire is which...like me.
PS - I have the Haynes AND
the Chilton "Manuals" which are almost
useless except for toilet paper. Leaves out quite a lot of stuff.
Hitman - CUTE ! Probably works on women at the repair shop !
