1994 4x4 cheverolet silverado blazer

We bought the truck used from an auto dealer, and it came with a, keyless/remote start

alarm system, (Code Alarm). The keyless entry quit working one day, we check the fuses and

replaced it, but after we did this, we noticed that all the lights on the truck were workind

except for the rear running tail lights. We would really like to get the wiring diagram on the

vehicle so that we can just remove the system, the alarm nerver worked on it since we have

owned it and really could careless about remote start.

thank you

While we were waiting for your response, we unhooked the alarm system, but still no

running lights. Here's the deal, we have brake lights, directionals,back-up and rear hazard

lights, all front lights work, just no rear running lights. The rear signal lights, and running lights use

the same bulb, so we know the bulbs are not bad. Still only the signals work. There must be a wire

broke somewhere in the electrical system. Is there a wiring diagram on this vehicle that will

show us how and where the wires run through out the truck, so that we may trace the wirring for

possible breaks, we have check the wire that runs along the frame, or do you have any Ideas of your

own.

We called 2 dealer service departments and they were clueless, and I'm not to sure it's in the

Alarm system.

Thank You
