2002 Trailblazer Intermittent Electrical Problems

Unread post by md1 » Mon Dec 17, 2012 5:08 am

What can we do about intermittent electrical problems? First the low beams go on and off, whenever, never leaving any code. The the Onstar mirror indicator light turns red and green and on occasion, no light. Transmission 4WD light indicator, and transmission slips out of the running setting, allowing the engine to spin rapidly, but we don't move. Put it in the next higher setting, and the lights blink. The N red light blinked one day, but I haven't seen that again. CHECK 4WD light comes on the dashboard, but goes out! Again...no codes are recorded for mechanics to research. I've already spent lots of money to get this car back to running while on vacation on an across country road trip, which is bad since when they fix the car in one town, and if that didn't work you can't take it back to them without turning back and adding more to your vacation costs! Doesn't Chevrolet care about it's customers. There are so many questions on websites about the Low beam headlights....wouldn't your think they would have a fix for it?

Well, after reading and answering your other post about the mirror problem you may just have gotten too much rain into the vehicle and really caused some havoc with the entire electrical system.

I cannot give you an answer for every single thing on your list of problems. This would be something that has to be diagnosed in person by a technician when the problems are actually acting up.
