I had the same lights flashing on my 2003 Grand Am. It all started in wet weather but did not completely go away when it got dry. I have read a lot of posts here and other places, but tried the simple route first - check fuses and connections. I checked the fuses by completely pulling them out - one at a time. While I had them out I coated the blades with a light coating of dielectric grease. After all were checked and greased, all the flashing ABS and other lights went away. No guarantees, but a pretty cheap fix that may help with your electrical problems..
Good luck,
Jim

so tired of this car by jom72498

are you ready for the novel?? lol ok first my car started not starting every time you went to start it. it would take a couple times to actually start then it went to taking 30 or 40 times to start it. so they told me to replace the battery i did. it continued to do this and then it started to turn off while driving and the battery light would come on so they told me to replace my alternator so i did. it continued to do the same thing so i took it and paid 65 dollars to get it put on the computer and the computer printed out all the codes on the car saying everything on the car was bad the man said that meant my computer was bad so i called around to the dealer i bought it from to see if they could reprogram a new computer they told me to let them see it they put it on the GM computer and nothing came back wrong with it so they called me to come get it i did the next day and it wouldn't start they looked at it and said it was the starter they replaced that well still the lights came on (check engine and trac off) so then they said it was the ignition switch which we replaced and ran good for a month and a half and then when the trac off was on the transmission switched gears so hard it would nearly jerk you out of your seat so we would stop and put transmission fluid in it and it would stop we did this for months and come to find out that i put too much in it because it didn't need it. i took it back they said they couldn't find anything wrong with it cause it always ran good when it was there. still the lights would come on and took it back and they replaced the throttle control sensor??? or pedal position sensor (they are the same thing i think) the light still came on once or twice a week and when you are going over 50 mph the car will sometimes jerk like the RPM's will go up and down and the speed-o-meter will do the same. then one night the ignition got stuck while the car was on... i couldn't turn it off so i took it and they replaced the ignition... and worked ok for a month now the trac off light comes on twice a week or so and the service engine light too and when i comes on autozone scans it and says its the pedal position sensor (which i already replaced) also sometimes while the trac off light is on the windows will not roll up or down and then a few hours later they will work fine and also my trunk pops on its own. if the lights are on and you turn the car off for a while the lights will go off but the transmission will only switch from first to second gear if you let off the gas (and that is always except when the ignition was stuck on the car drove perfect i mean perfect you just couldn't turn it off lol ) ok so i think that raps it up. every mechanic says it is just a short somewhere that is making all these things go bad and no one can find the short what do i do? i really hope someone has had this problem please help

my low coolant light wont go out! by tracys68

I have a 97 grand am,2.4 with 193,430 miles.I recently had to replace my radiator.My coolant level is full,so that is not the problem.Also Ive had to replace the wire and plug that plugs into the coolant temp sensor since my fan would not come on at all and still dont by the way!Ive replaced the relays for the fan,fuses,temp sensor and Ive even had to wire the fan direct.Why is it my antifreeze is not getting as hot as its supposed to?ive also had to replace the transmission line going from the radiator to the trans and now my transmission shifts hard.But anyway,I guess since my car is not getting very hot that is making the fan not come on or is it due to that low coolant light that wont shut off?Guys at autozone and advance auto dont have clue as to whats wrong with it can someone help me with all this?thanks

The low coolant light is operated by a switch and float in the resevoir tank. If the coolant is up to the full mark and the light is on then probably the switch or float is bad, or just like my old 95 GA was, it just gets stuck. Anytime I had to drain the cooling system I always had to shake the resevoir tank to get it unstuck.
As far as the coolant temp, since it's winter and you have a new radiator then maybe it's just normal? The low coolant light itself won't have anything to do with the operation of the fan.
193K is a lot of miles for a Grand AM!

ok thank you for your info.I did notice that there is a plug in of some type connected to the bottom of the resivior tank.do you know what that is?Also shouldnt I be worried about the fan not coming on at all? You seem surprised that my car is still running with all the miles I have on it(ha ha)Yes that is a lot of miles but when you dont have the money for another car you make due with what you have right?thanks again for the info and I will try that with the tank and see what happens!

The connector is the wiring for the low coolant level switch. I wouldn't worry about the fan unless it's running hot. Not knowing where your from I don't have any idea of the ambient air temperature. If your in Minnesota, for example, it may be so cold it won't warm up, if your in the Southwest or southern Florida I would feel different. If it never seems to warm up at all you may need a new thermostat.

the same thing happened to me in my '03 GA, but the trac off light didnt come on, i took it to a dealership, and the diagnosed the problem as a bad bearing in the fuel pump, thus causing the car to shut off while on the freeway. the dealership quoted the repair/parts and labor to be a grand total of about $734. That fixed the fuel pump, but the car is still stalling in the middle of the road, thats why i will be selling it to a dealership soon.

2002 grand am ABS, Trac Off, and Service Vehicle soon lights by stealthyj47

These lights all came on at the same time and I took it to VIP and they said it was a computer issue and needed to take it to the dealer.
 
Also, a couple times when coming to a stop there is a grinding sound (abs??) and the car slides a few feet before stopping. It has only done this twice since the lights came on almost a week ago. I have an appt with the dealer in a few days.
 
HELP ME! what could be wrong and how much could it cost!
 
Thanks,
J

My fuse coating did not work for long. I am still looking for a solution on-line and may try another dealership but will try to get a guaranteed repair. I still like my Grand Am and wild buy another, but I am troubled about all the problems I read on-line. I realize two things, there are a lot of Grand Ams on the road and the dealerships must all be worthless.
