#6 of 14 02 Chrysler 300M Heating Problems by tzerwas Jan 17, 2008 (7:10 am)
Hey Folks,   Newbie from MN here.   I used to be able to start my car, let it run for 5-10 minutes and I would get some heat in the winter.   But the past couple days I start it, let it run and it still blows cold air when I get outside. It will only heat up while I am driving, and when I stop the car for a short period of time (At an intersection or something) it starts blowing cold air again.   What gives? I'm not a car buff. I just had the thermostat replaced so I doubt that is any problem. Any ideas for me??
#7 of 14 99 300m heating problem by shar6 Mar 15, 2008 (7:31 pm)
I have a problem with the heating system in this car and after having all the sensors, computer control module, actuator door control and thermostat replaced x2, It still blows cold air. Temp gauge stays at midline when parked but drops to C when being driven. The dealership had it for a month and flushed the system, checked the hoses and heater core and replaced all the parts mentioned before with no luck. They have no idea why I cannot get any heat. I love the car and wouldn't mind if I lived in a warm state. I do have ice cold air. Has anyone had this problem and been able to have it fixed? My kids are tired of wearing ten layers to stay warm.

#9 of 14 Is it worth it? by raygon Jul 26, 2008 (5:54 pm)
Hello! I recently bought a 99 300M with 231, 000 kms. on it. Body and engine are in very good condition. The only thing wrong is that the airconditioner does not work. The fan and heater works but it doesn't cool. The a/c compressor clutch does not even turn.   I brought it to an a/c shop and was told that they can try to vacuum out the system and load freon and charge me about $225, but there is no guaranty that it will cool down. The a/c technician even warned me that if it is a major damage or defect, it could cost me over $2,000 to fix it.   My question is, is it worth having it recharged for $225 and if at worst spend $2,000 for fixing the a/c? Is there a way I can find out what is wrong with the a/c without spending serious dollars? Please advise. Thank you.

Replying to: mark628 (Nov 12, 2008 6:50 am) Hi Mark. Unfortunately, until now, no one has responded to my question/request for advise. I still don't know what is exactly wrong with it. The heater works well but not the airconditioning.

Replying to: raygon (Jul 26, 2008 5:54 pm) freon is not going to fix this if compressor is locked - have you checked all fuses....check to see if power is going to compressor than if you need one get one at a junk yard for about 50 bux you would still need freon .....and if you want to recharge go to autozone or the like they have a kit for 29 bux works just fine and very easy to do...just twist it on....if you have a cute girl go in they may do it for her...but seriously...dont waste time on freon if compressor is locked.

Replying to: debleebee (Nov 17, 2008 6:23 pm) Thank you very much for your advise. Very much appreciate your taking the time to respond. I am not much of a handyman but I will certainly try your suggestion. How do you check if power is going to the compressor?
#14 of 14 Won't Get Cold by adamcole83 Jun 13, 2009 (11:41 am)
I have a 1999 Chrysler 300M, one day I noticed a fog coming out of the vents when I had the AC on, then it felt like the car didn't want to give out cool air. It only happens when it is really warm outside. I look at the outside temp and it says a temp that is usually 10 degrees cooler than what it is. Like today it says 75 and it's really 84 out. When it's cooler than 70 outside then the AC is freezing cold. What could it be? I checked the freeon and it was full.
