My 1999 Pontiac Grand Am SE 2dr 4cyl automatic transmission is messing up. When I open a door, bump in to it, turn it on or do anything that involves electricity the car lights start flashing and clicking and if I hadn't turned of my alarm horn it would beep sometimes. It will even start flashing when I come to a stop light, and the engine is still running. It does this every time!



My pass lock light on the dash is constantly FLASHING. This all started happening a few months ago when I let my friend drive the car and the battery just died, I replaced the battery is there anyway to stop the flashing and clicking? It is driving me crazy. I have to turn my headlights on during the day so people will not think I stole the car.



Is this my pass lock? I can start my car every time and the pass lock light is FLASHING not staying on constantly. Can I expect my car to stop starting any day? We tried to cut the yellow wire attached to the ignition but it didn't do any thing because I can start it every time so I doubt it is my ignition/ignition sensor. Please help I don't have the money or want to spend it on a dealer fixing it. I keep reading about installing a remote start to bypass the pass lock but my car STARTS. What do I do?



I tried to "re-learn" my car, nothing changed. I left it in the "on" position and the alarm light just kept blinking. I did the crank but don't start, leave on for 10 min, turn off for two min and repeated it



3 times and still no change.

Just yesterday it started doing something new... it will unlock itself at random...while I am driving when I'm parked and best yet I locked my car with the remote than when I came out of the store I lifted the door handle and it just unlocked itself! That will really keep a car thief from taking it!!



I have been searching the web for months on this problem but all I can find it problems with the passlock and ignition cylinder. The previous owner as a genius when he decided to install an after market alarm in the car when it already has a stock alarm. Could the two alarms be "fighting over control"?



Very possible. Always look for previous work when making a diagnosis. I'd say strip that crap out of there check all the wires and connections and see if the problem continiues.
