I m having trouble figuring out why the radiator fans wont turn on, Even when the ac is turned on it still doesn't turn on, I changed the coolant temp senser. still nothing, i also ran a whire from the battery to the fan and they both turned on. I also stitched around relays and checked fused still nothing. 2000 pontiac grand am 2.4L engine 4dr auto trans.
View 14 RepliesI have a 2000 grand am Gt with 3400 motor it started up just fine went to turn around in the drive way the dash lights came on where the ABS sensor is bad, but if u shut it off and started it back up they would go out so i shut it down and went to start it back up and all it does is click, so i thought it was the starter and replaced it, still only clicks. I called GM dealership they said more then likely it is the plastic piece the ignition switch goes in to so i just replaced it and does the same thing.
View 8 RepliesHave a 2004 Grand am that was having some problems starting:
1) The last 10 times it would start cold, but it would take about 5-10 seconds of turnover before actually starting.
2) After it started, it would start fine the rest of the day.
Now it will not start at all. Today is the coldest day of the year so far... 43 degrees. It tries to turn over. The security light came on once, but did not come on again (i know that's a common problem). (note: I have not seen it in person, but will later today). Either fuel or spark.
My thought: either fuel pump, fuel pump relay, sensor, wires/plugs, etc.
I have a 2001 Grand Am that I cannot get it started. At first it was an intermittent problem and now I cannot get it started period. When it was intermittent I took it to the dealer and they could not find anything wrong. When I got the car home and try the next day it now won't start. It tries to turn over but won't. I put a new battery because I drain the old one. Change the fuses but still no luck. The fuel pump I was told was okay.
View 4 RepliesMy wife has a 2000 Pontiac Grand Am, as seen above. The car recently started having issues, especially when cold, where the RPMs will rise when in gear but the car will not accelerate. It happened from 25 mph and lower while in a subdivision as well as around 45 mph on city streets. I have a feeling this is a transmission issue, but don't have much experience when it comes to transmissions.
View 6 RepliesI have just replaced an almost new oxygen sensor on my 2000 Grand Am. After about 40 miles, the check engine light came back on again. I have not had a chance to check it, but I assume it is the oxygen sensor again. What am I missing?

View 4 RepliesSo this seems to be a common code that is thrown when you near 100k miles, I'm at 77k .. This thread seems to be the most organized [URL] ....
"Long story short, there are 5 main reasons this problem can pop up, listed in order of likelihood, least to greatest:
1) Coolant sensor
2) Thermostat
3) Bad fans
4) Coolant mixture
5) Water pump "
My issue is that the only ones I'm (probably) able to rule out is coolant mixture and bad fans. My radiator fans do turn on from time to time, so I thought I'd ruled that out (unless it would throw a code for not turning on at appropriate times?)
I heard of a test to turn on your AC and see if they turn on, but my AC hasn't blown cold air like ever, so I don't know if that affects the test (probably not?)
A couple years ago I had a shop replace the original thermostat with the new one, or was it the coolant sensor, or both (ugh, I don't remember!) That leaves thermostat, coolant sensor, and water pump.
I guess my main question is is there anyway to find out which it is between these 3, without spending so time, money, parts etc? It doesn't seem the coolant sensor is easily accessible for one.
My car has been really slow recently but I also need to change the spark plugs, I'm doing that this week. I cleared the CEL/P2181 code and it returned a few weeks later,
I'm starting to change my mind about this car being easy to maintain/reliable, I'm always on time with maintenance and with only 77k miles on a 2004 car.
My wife's 2000 grand am 2.4L engine is acting really funny. this is the first problem we've had with it. i was driving it to pick up my kids from school. on the way i stopped and got some gas from the marathon then drove about 5minutes and it started running really ruff lose of power wouldn't go above 30mph seemed like the transmission took longer to shifter to.
i made it to the school as i was about 2 1/2 blocks away. got my kids check the oil and it was really low so i got 2 quarts as it was a gas station in walking distance. i thought it was a lil better but i started driving it and it had the same results. i got it home about a 10minute trip regularly and parked it.
the next day day it ran then stumbled hard. and every time i tried to start it got the same think was like a lock up. it did crank but when it tried to start it stumbled or locked up. i pulled the plugs had some wet threads oil was on the first on and the threads and around the spark plug b4 i pulled it out.
2 of the other plugs had red stuff on them not on the threads though. here are some pictures also i will show a vid of what its doing. i did a compression test and here are the numbers starting with the first one with oil on threads.
190-194-200-190+ compression test with cold engine.
Also smoked puffed up not sure from where yet..
The Change Oil light was illuminated for a short time on my 2000 Grand Am. This morning, on the way to get the oil changed, the Service Vehicle Soon light came on also. After the oil change, the Change Oil light went off, but the Service Vehicle Soon light stayed on. I stopped by my mechanic, who doesn't like to change oil, since it does pay enough, and he said that there was something else that they should have done to reset this other light. He said it was in the manual, but I don't find it. How to turn it off?
View 4 RepliesI'm having an issue with my fans on my radiator. They don't turn on when the engine gets warm and the A/C is off. I've replaced the crack pipe, water pump, and belt tensioner. I've replaced the fans not to long ago because the low speed wasn't working. I tested low speed at the fan connector and it wasn't working. After replacing fans I tested and it was working when jumping the pins on the thermo switch connector. I got both low and high speeds to work during that test. I've since replaced the thermo switch to see if it would fix the issue but the fans still won't come on without turning the A/C on. Any other tests I could do or should I just try to get another thermo switch.
View 4 RepliesI have an odd problem. My AC will not activate until the engine gets hot enough that the radiator fans turn on. Once they do, the engine RPMs drop, the clutch kicks in, and I get frosty cold air with no problems. I already replaced my FCM and checked all fuses. It worked consistently all last summer and considering the AC is nice and cold once it kicks in, I don't think this is a pressure issue and it was recharged at the beginning of last summer by a good shop.
I changed my coolant flange a few months ago, same temp sensor. Didn't try AC back then as it was cool outside still. Could this have something to do with it? I have proper readout on my dash. Maybe it's the ambient temp sensor?

I have a 2000 Grand AM cylin. Recently I was driving when my car started to shake violently. I drove it to the side of the road to a parking lot then it died. I started it up again and is ran but shacking a lot again. Once I got home, 3 blocks away the car died again. I tried to start it again but it would only turn but not start the engine. I have checked the gas pump, motor mounts, oil and anti freez for oil. I did check the timing chain but I don't know much on how it should be.

View 13 RepliesI have a 2000 Pontiac grand am coupe GT with the 6 cylinder engine. It has been a very good car to me. I really like it and it "fits" me well ... and yet... it is now testing me. About a year ago the check engine light came on. The codes were P0327 and P0336 for bad Knock sensor and Crank sensor respectively. The were both replaced multiple times, the light still stays on... and the codes are still coming up. I have have been to different experts, and after the computer resets... there they are again. (someone even thought that the computer needed updated codes for those sensors... so he installed them.. with no better results). The code P1189 for an oil switch is now coming up too.Here in California, the car cannot pass smog with the check engine light on... so I'm not able to re-register it, and I don't think I can sell it for much because no one can register it now. So, what this can be? Is there some common thread between all these sensors (or a recall of some kind) that would explain this? My fear is that the computer will have to be changed at about $1000. My even greater fear is that that will still not solve the problem.
View 2 RepliesWas driving on the highway and all of a sudden my mph gauge just drops and my car slows down. This is the first time it happened and it didn't do it again after I got off the highway. Other things it has been doing: eating gas, shifting hard, and doesn't want to get up to speed. Not sure if they are related to this new problem or not.
View 2 RepliesI have a 2000 V6 3400 engine. I had the intake gaskets repaired with the "good metal ones" according to the mechanic I had do the job. Cost me $600. Car still has coolant leak it overheats every 3 days or so. Leaves no puddles under car when parked. Can smell coolant when stopping at stop light or stop sign or when parking car. No obvious coolant running down or pooling on the engine. Sometimes it seems like smell is coming from heat vents but no wet spots on carpet or liquid coming out of vent. Took to mechanic again and he said it was the head gasket leaking. Wants $1100 to fix it. Don't have the money. Was wondering if any of these additives you can get at Autozone Etc. may work. It wouldn't be my first choice but financially it's about all I can do right now.
View 2 RepliesI replaced the ignition key lock cylinder on my 2000 Pontiac Grand Am SE. I performed the re-learn process by cranking the engine over, then releasing to the ON position for about 9 minutes. During the 9 minutes the SECURITY light blinked the whole time, then at the end it went solid for a few seconds, then off. On the next cranking cycle I was able to start the engine and thought all was good. But now when I open the door the car beeps as if the key is left in the ignition and the automatic locks are disabled with the door opened.What is the problem and how do I fix it?
View 1 RepliesMy Camry seems to be overheating. When I'm driving the gauge maintains and reads 6/10, when the engine is idling, it goes upto 8/10, radiator fans kick in and then temperature goes down to 6/10 and keeps cycling over a period of 5 mins.
It's got 100K miles, water pump has not been replaced yet.
I checked the hose temperature; top hose 210 F, bottom hose 192, fans kick in when top hose is around 215 F.
I checked the engine temperature where the sender is installed and it was reading 205 F. Coolant level is OK. I burped the system. Previous owner told me, he had thermostat replaced by dealer.
So my radiator fans were staying on until my battery died and my car was completely cooled down and off. I was told it was a sticking relay so I replaced it and the fans still won't come on. I unplugged the coolant temp sensor and the fans came on so I know its not the motors or anything.
View 5 RepliesI have a 2000 Dodge Grand Caravan that has 195,000 miles. My radiator fan won't turn on and I'm stumped! The issue presented itself with a check engine light and the radiator cooling fan not turning on. The trouble code indicated the cooling fan relay was faulty. In all cases below, I tested the radiator fan by turning on the air conditioning (thus forcing the cooling fans to run) and also for it to come up to a high temperature coming close to the danger zone.
1. Fuse - first tested the fuse and it was OK. Had to start with simple things first.
2. Cooling fan relay - I replaced the relay which has a reputation for failing on the Dodge. Still the fan did not kick in.
3. Cooling fans - tested the cooling fans and the motor was seized. Replaced the cooling fans and tested them by jumping them. The cooling fans still do not turn on. There is no voltage leaving the cooling fan relay and coming into the cooling fan harness.
4. Wiring - tested the wiring between the relay and the fans. They checked out OK (good continuity and resistance check). There is no voltage leaving the cooling fan relay. Now it's getting more complicated... I unplugged the wiring harness from the ECM and tested the wiring between the ECM and the cooling fan relay. A-OK.
5. ECM - it is unclear how to check the ECM for functionality of the cooling fan.
There are 3 wires (supply, ground, and switch wire?) The supply voltage and ground is good, but I don't know what voltage the switch wire should be. I've read that it is pulse width modulated so I can't measure this with a simple voltmeter. I've also read that the switch wire goes to ground thus triggering the relay. I don't know which is correct. Several mechanics I talked to were skeptical that the issue is with the ECM, they knew of very few instances of this being the culprit. I even replaced the new cooling fan relay with another new cooling fan relay on the off chance that the replacement was faulty. Did I miss something in my logic and diagnostics? I've resorted to wiring a switch directly to the cooling fans and toggling them on and off.
