I have a 1999 Chrysler 300M that has the Automatic Temperature Control (ATC) Unit fan stuck on high no matter what is selected (Auto, Manual or OFF). It comes on high when I start the car and cannot be turned off. I check the associated fuses (OK) and looked for stuck relays, but there are none associated with the ATC. Any ideas? That seems to leave the two ATC sensors or the fan switch itself?

Bought my 99 300M about a month ago. After I purchased it, I took it to the car wash and when they were done with it, the car wouldnt start. I took it back to the dealer who said it was a bad battery. They supposedly replaced the battery and it started up fine for the first month. I then took it back to the same car wash and got it washed again. After that, I took it on a 200 mile road trip. It ran fine. When I went to start it the next morning, the battery was dead again. I got it jumped and it ran fine. I drove about 75 miles to a Wal Mart to get the battery checked out. when I got there, I turned the car off and then tried to start it again. It started right up. I then tried it again and it started right up. I decided to forgo Wal Mart and continue my trip. I drove an additional 80 miles and parked at a hotel. When I returned to the car about an hour later, it wouldnt start. I then got a jump and drove it home. I parked it and will leave it parked until I figure out why the battery dies. I believe its either something getting wet when I take it to the car wash or something shorting when the car is driven on long trips. I really have no other idea at this point. I did notice that close to the end of the 200 mile trip that the engine didnt seem as strong as it did at the start of the trip. The car has 99,000 miles on it and the tranny seems fine. The only other issue with the car is that the midrange speakers need the cones reglued. Other than that, I believe the shocks on the trunk lid could be replaced. The car is in excellent shape and I really enjoy driving it. I hope the electrical issue is something simple to fix like just replacing the battery with a good new one and witnessing the store install it. Anyone else have this kind of issue?

Replying to: crdivoff (Apr 20, 2008 3:02 pm) i also have a 99 300M, mby battery just died out on me this eve, i couldnt figure out why, i jumped it and it ran for like 2 mins and the engine dies out while i'm moving, i was just happy I hadn't hit the high way. a friend who helped me jump start suggested i'm having a problem with the dynamo, i guess like crdivoff mentioned it may be called other wise. from what i've heard from others, a dynamo replacemet makes a huge hole in the pocket. i'm gonna be taking it to the garage cause the company is a rip off..! nothin new.. well a reason for the battery to die out is because my tail lights dont go out sometimes and if i dont check it, it takes a toll on the battery. however, 2 things that i need to know, is a dynamo / generator a possible problem? or is it the battery? and should i get the wiriing checked? |

| I have a 2000 300M. The last two years I have had a sound in the engine that I will describe as sounding like a air pump leaking air. I have this sound only when the car is driven...never at idle. When the car is at idle it runs and sounds like new but once under way I can hear this sound more and more. To my knowledge there is no air pump on the 3.5 engine.. Any thoughts would be appreciated.
