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
back feeding. Turn signal switch is also a possibility, but those rear circuit boards are usually the cause.

2003 Pontiac Montana van.
Question = have a 03 Montana van with dual sliders left side caught fire due to short i think any way
would like to make this a manual door so it will open again any tips would be greatly appreciated thanks.

You can make this a manual door. Without going into the interior trim panel and removing the entire
power motor assembly, we have converted these doors to manual by cutting the cable that works the
door, on both ends. A cable comes from the rear of the door, and one cable from the front and they both
attach to the door roller.

You need to cut it as close to the end of the cable- not close to the door roller. Then you can remove the
remaining cable from the roller. The door will still be a little stiff opening and closing, but not as much as if
the cables were still on. You would also need to turn the power door switch to off in the overhead console
switch. Or get to the module and disconnect the wiring harness to disable it.
