I have the same issue. In my situation, I notice blowers run louder & longer than usual. My guess is that the car thinks it's overheating. I've had it in and the error cleared (whatever that means) and it's fine for awhile...then the same issue happens. Have you found anything out?

I have a 2004 Impala with a 3.4 engine the temperture gauge shows that its hot at least 210 F.
I leave the car running and remove the radiator cap and the water is warm what is the problem?

I also have a 2001 Impala with 76k miles and the temperture gage goes more than half way when I drive below 30mph or when I am stopped. Took it to a mechanic and said it was fine. I'm going to get a second opinion.

I have had the same problem, although I've still been able to put over 90,000 miles on it. It's weird

My gauge just stopped working yesterday, and tonight when I turned it off the fan continued to run for about 2 minutes. Any ideas yet?

2001 monte ss
same problem as mentioned
check engine light comes on and temp gauge goes to zero I had the code pulled and it points to the temp sending unit put from whats being posted folks have replaced and are still getting the check light now i'am not sure it's the temp sending unit. another odd problem reminds me of same car after a fill up the compass go baserk this was when it was under warranty they replaced the compass diplay unit same problem.

HI, I had the same problem as many of you. I have a 2001 Impala LS and my temp gauge was not working at all and the blower turned on as soon as I turned on my car. To add to the problem my "check light" turned on. I just went to my chevrolet dealer and they told me the problem was due to the thermostat of the car, I have it repaired right now and hope it will work. The biggest problem is that it cast a shit load in labor. If you know how to change a thermostat, just do it it will cost you between $8 and $16 only.

I have a 2001 Chevy Impala LS with about 102k miles. Great car with a few minor nuisances once in a while like the one being described here. I noticed occasionally that the temp guage is not working and that sometimes the cooling fan runs after the engine is turned off--kinda loud actually. Between this site and others I've found possible problems could be leaking intake manifold, faulty thermostat or fault coolant temp sensor. Not sure if related, but I also swear that I smell oil burning--of course, maybe that's just from changing my oil....I'm considering purchasing a thermostat and changing myself--well, I've got a Haynes Repair Manual that I'm hoping will walk me through it. Any other ideas what might be causing this problem?

2001 Impala...basically the same problem. The fan runs about 5 minutes after the car is stopped and today the temp gauge isn't working. I do have heat, but it doesn't seem as warm. Have not had the check engine light come on. Does anyone have any ideas?

Just reporting back what I tried over the weekend (before watching the COLTS beat New England). I found a couple of FREE recommendations before going out and spending any money. First, I removed the negative cable on the battery. Then I removed the PCM fuse (found in the top fuse box under the hood on the passenger side) and replaced (with same fuse) after 10 minutes. Then I removed the ground wire (found under the hood on the driver's side above the headlight) and sanded/scraped any paint off of the body of the car at contact point; also sanded down connections and the bolt. Finally, I put everything back together and haven't had the problems in two days. I'll follow up in a week or two to let you know if it continues to work fine.
