Does anyone have problems with a 2002 Pontiac Grand Am electrical system?

Question

All instruments lights flash for no reason.....

Answer 1

I have a grand am and have never had electrical problems. some problems in the electrical system are caused by aftermarket accessories (remote car starter, stereo etc.)- if you have none of those, it sounds like your BCM (body control module) is failing.

Answer 2

It sounds as if you are expierencing an intermittent fault. I would either suspect a main ground in the instrument panel area or the motor area. Check all modules for codes as this can be a clue with proper diagnosis. If there are theft codes in it but cannot find why, I would think you have an ignition switch with a resistance across some of the contacts which can cause all sorts of problems. If that is the case, replace the switch only as the lock is still good.

Answer 3

all grand ams have electrical problems, I have a 94 that sometimes the dash lights and head lights will go off for a couple of seconds and the low oil light and check engine light will flash once in a while for no reason at all, I look at the oil pressure gauge when it does that and it shows 40 lbs. of pressure so there is nothing wrong just typical grand am.

Answer 4

Grand ams "n body's" also Malibu's had problems with the ignition switches. They would have intermittent open in the switch that would cause the instrument lights to go into a bulb check mode.

Answer 5

Clean your battery terminals and make sure that they're bright and shiny. A bad connection there can goof all kinds of things up.

Also, you might want to consider getting your alternator tested as well. Good luck!

Answer 6

No, but you can get a schematic off of your on line local library database. I am not sure where you're located but you should be able to sign on and access with your library card.
