Problem with my 2002 Pontiac Montana
3.4 V6 Engine
work done prior = coil pack,plugs and wires
work done to repair = none
tech = jk
question = My tail,turn,brake light do 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.
JK:
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 backfeeding 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 back feeding. Turn signal switch is also
a possibility, but those rear circuit boards are usually the cause.

2003 Pontiac Montana changed brake light switch.
Question = rear brakes light do not work. The top one does but the two main one do not. All bulbs are
good and have replaced the brake light switch. Any ideas what it could be?

Answer: Your style van has been known to have problems with the circuit
boards that are attached to the back side of each taillight and hold the bulbs.
The bulbs can check good, but if the circuit board is bad, they will still not light.
These are fairly easy to change, and I usually recommend using all new bulbs
when you do replace the circuit boards. You can try checking for power at the
connector to each taillight when the brakes are applied and you would know
for sure then they are faulty. If you have no power back there, and you're sure
you installed the new brake switch correctly, there could be a wiring problem
somewhere between the switch and taillamps. That would take a great deal of
circuit checking, so be sure to check out the circuit boards first.
