Light problem with my 2002 Pontiac Montana
3.4 v-6
Replaced coil pack, plugs and wires
work done to repair = none
tech = jk
question = Why does my tail, turn, brake light not work. The fuses and bulbs are
all good. When I hit the brakes shifter,and turn indicator lights go
dim. Please help me,I have to leave town(sick family 3000 miles away) my
wife needs to be safe. Thanks! God Bless.

Sounds like you have a short or other wiring problem. A common area of odd
electrical problems for rear lights is the circuit boards in the rear assemblies that
the bulbs plug into. Sometimes they short out internally, and cause back feeding
into other lighting circuits. Also, look into the plug for both of those circuits, and
look for corrosion. This assuming that all bulbs ARE good. The incorrect bulbs,
or bent terminals on the bottom of the bulbs can also cause this sort of
backfeeding. Turn signal switch is also a possibility, but those rear circuit boards
are usually the cause.
