I have a 2002 Chevy S10 with an electrical problem.
All manual, no electric mirrors, seats, locks, windows, etc. and no trailer
It does have air conditioning and curse control.
V6, TBI, two wheel drive.
Never in an accident and only used for paved roads.
A few days ago, the rear lights came on and will not turn off, even when the
truck is not running or even have a key in the ignition. If I turn on a
blinker then that (right or left) bulb will blink on and off, but as soon as
I turn off the blinker, the light goes back on. I pulled the connector to
the break switch on the break peddle - no change. I then pulled the
hazard/blinker unit from behind the glove box - no change. Looking at the
electrical diagram in the Haynes manual, pulling these two things should cut
off any supply of voltage to the circuit, but it does not. The manual only
shows two fuses for the circuit but there are three fuses in the fuse block
under the hood for these lights. I put the blinker and break switch back in
and the lights started to work correctly - for a day. The problem came back.
The lights go out when I pull the STOPLP 20 amp fuse, but then I have no
turn signals or break lights. If I pull the LT TRN or the RT TRN fuse then
the corresponding light goes out, but then I have no blinkers. If I turn the
hazard switch on then I hear one click and the dash lights for the turn
signals come on and stay on. Every once in a while the problem will go away
and everything works correctly, but soon comes back.
Any ideas what I should check next???
