my low coolant light wont go out! by tracys68
Jan 14, 2008 (6:43 am)

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.

I had a similar problem with my 98 Grand Am. From time to time, it also would not start. It didn't act like a dead battery, but after a battery charger indicated that it might be a bad cell int he battery, I decide to replace it. When I went to remove the terminals, I notice that the positive one was corroded on the inside and was difficult to remove. Just for kicks, I removed the bolt and cleaned it up and put it back together.
 
Not only did it start right up, the lights on the instrument panel quit coming on intermittently, the radio display stayed on all the time and the volume control started working correctly.
 
All of the electronic gizmos on cars these days are great when they are working, but they sure don't seem to tolerate voltage and current variation well!
 
Now I have to find out why the fan won't kick in all of the time, causing it to overheat... (I'm at 214K miles, by the way...)

Computer/PCM by jdbonill
Apr 16, 2008 (12:30 pm)

I am not a car guy by ANY stretch of the imagination. I have recently had a lot of trouble with my RPM's being way high in idle. Took it to the mechanic, and after a bunch of repairs, he still said that I need a new computer (PCM). He wanted to charge me about 600 for just the part. I have found the part new at a much cheaper price, and was told it was easy to repair. The problem is, I cant seem to find the computer under the hood. Any advice? I have a 2001 pontiac grand am, 2.4L
