I have a 300C which I bought new on 22 August which now has less than 1,000 miles. I went on a short trip in S. California during a hot spell. Twice on the way the A/C froze up and twice on the return the A/C froze up again. The A/C was on full auto with maximum cooling requested on both the driver and passenger. Slowly the A/C level declined until complete freezeup occured. Shutting off the air and opening the windows helped the unit to thaw. I took the car into a 5* dealer and they said they could not duplicate the problem. After coming home from the dealer I entered this GREAT website and found the TSB 24-012-05 for the exact same problem with the A/C. My complaint was why did the dealer not know about the TSB and use it to reprogram the HVAC Automatic Temperature Control (ATC) as stated in the TSB while I was in there. I called the Service Manager and he told me they did not have the CD version of the flash update and that he would call me when they did get it. I reread the TSB. The TSB clearly states that the dealer can get the flash from the Internet site for Chrysler StarScan flashes that they have access to. I have a call into him to find out why they can't update it via the Internet. I did call Chrysler Customer Service about this and complained. I am waiting for the Service Manager to call back. Has anyone else had this problem? Will advise what happens. Regards, Bob.

Bob - Can you tells us what SoCal dealer, or in what area of SoCal this occured? Many of us live down here and might be able to provide some assistance...

FWIW, my 06 300C (build date 3-31-05) hasn't exhibited any AC failures nor flaws in 7000 miles, and we've been through some HOT 105+ degree days here in the SFV!

Cheers... :wave:

Hi. Thanks. I appreciate it. Are you saying that they had the wrong controller installed when you bought the car? Did they have the new one in stock or did you have to go back again to get the new one installed? Do you know the wrong and right P/N's? Any help sure would be appreciated. Thanks and best regards, Bob.

Follow-Up

Here is a follow up report:
Called Chrysler Customer Service. They set me up a complaint file number and were supposed to do something and have someone get back to me via phone today. Naturally nothing happened! Called Customer Service back and asked what happened to my file number. They said they contacted the dealer, which they did not, per the dealer. I went over to the dealer and they confirmed no contact from Chrysler was made. The Service Manager called a Dodge dealer and got the 6.02 CD update and installed it, updated it via the Internet and install ed the flashes to the HVAV and all of the other modules that needed updating. I wanted the updated HVAC per the TSB before I go on a trip to Arizona. Thanks to the friendly Service Manager, who I know well, I should be set to go. You can bet I will be on the phone to Chrysler Wed. and will follow up with a letter of complaint to the V.P of Customer Relations and the CEO. Thanks for all who helped me here. Best regards, Bob.

same problem here with an '05, happened during my trip driving to Montreal. What a pain the car was boiling hot, got to MTL and brought it to Chrysler and they told me the dealer had a recall on this as it is a known A/C problem, once it was fixed the problem has not re-occured.

TYPICAL A-HOLE SERVICE MANAGER WHO'S DODGING EATING CROW!!!

DUDE! Walk in there and TELL him to fix it. Don't complain to DCX. If the Service Manager doesn't do it, go to the owner of the dealership and explain your situation. He's being a douche!

 

[jjs]

What exactly are the symptoms of this problem...other than getting hotter while driving?

 

[BobF]

Not the Manager's Fault

Hi. It was not the Manager's fault. He did not have the disk. He does now thanks to a Dodge dealer. I was there when he called and got it. It's Chrysler's fault for not getting him the disk. Regards, Bob.

Symptoms

What exactly are the symptoms of this problem...other than getting hotter while driving?

Hi. You keep getting lower and lower air flow from the cooling vents until there is no flow at all from any of the vents. Without the cooling air the car gets hotter and hotter. I had to open the sunroof, open the windows, and turn on the heat until the evaporator unfroze. The first time I stopped and watched the water pour out of the drain as it unfroze. It happened a total of four times until I got it fixed. I am going on a long trip to Arizona and will check it out. I hope it is permanently fixed. It is supposed to happen on long trips in hot and humid weather. See the TSB 24-012-05. Regards, Bob.

I have the problem and the dealer has flashed the automatic climate control unit in my car twice. Unfortunately, the A/C continues to freeze up are 3 hours of driving. By the way, you can have the system set to manual and the A/C will still freeze up. The dealer is going to install a new climate control head unit in my car next week to see if this will fix he problem.

Just a side note. The TSB is inaccurate. Yesterday morning, I left southwest NY State at 7:30 AM where it was 50 degrees heading home to Baltimore, and 3 hours into the drive, I lost air flow. The system was blowing heat for 2 hours before switching to A/C as it warmed up. So high temperatures are not the cause, and flashing the computer is not the fix, at least with my car. With winter coming, I plan to keep a hair dryer with a power inverter in the car so I can defrost the windows!!!!

I have resisted posting this since June. I'm now driving my 2nd 300C in a year. My '05 had some many electrical issues that Chrysler couldn't fix, they actually replace my car with an '06 this past June. See my original post last December 30th, name "numerous electrical problems". My '06 seemed okay until I had 4,500 miles on it, and the A/C problem started.

Finally, Chrysler will either fix this problem, or I will take Lee and his granddaughter up on their offer. I will find a better car, and I will buy it.

Just out of curiosity, have any of you who have experienced the freeze-up tried keeping your temp selector set at an intermediate setting, vice commanding full cold, and still had the system freeze up on you?

 

[XCITsNU]

Actually it is not high temperatures. The AC unit Literally FREEZES. It takes about 2 hours to thaw out. Totally sucks. Never happened to me yet, but I read all about it.

 

[BobF]

After having the HVAC flashed in my 2006 300C I went on a trip from Los Angeles to Laughlin, NV, where it was 103°F. The A/C worked perfect going and coming. The one way distance is around 240 miles. I just hope it keeps working. When it did freeze, before it was flashed, the drivers control was on max. cooling and the passenger control was on intermediate temp setting. Regards, Bob.

 

[Meister]

A...When it did freeze, before it was flashed, the drivers control was on max. cooling and the passenger control was on intermediate temp setting...

Thanks for the response, Bob. The reason I asked is that in over four decades of use I've never had an A/C freeze up on me when I've commanded 2/3 cold or less. I have had them freeze up on with great predictability when commanding full cold.

Like most things automotive, driver/operator technique can make a tremendous difference in performance of all kinds, including A/C output.

Do you have any details on this recall?

Any help or advice from anyone here on the board will be very helpful.

I have a 05 300C. I have a problem where the AC stopped blowing cold air on a long trip, it was blowing air, just not cold air. So I took it to the dealer, they told me they reprogrammed something and I thought that would be it. Well 2 weeks later im driving and I press the button to have the AC stop blowing cold air, but it kept blowing cold air. Then after a short while the blower would stop working no matter what the AC setting was. I could feel AC being produced when I put my hand over the vent, but the air wasn't blowing out. What seemed to fix the problem was turning the car off for a few min, then turn it back on. Now his has happened twice, so I took it to the same dealer and got the favorite one liner, "We couldn't duplicate the problem."

Any help or specifics on what I should do here?

Is this the same problem you guys are having?

Since my car is an 05 does this TSB not apply?

Thanks

A/C Quits

I experienced the same A/C problem. I was driving in Texas where the temperature was 85F and the A/C quit blowing after 1.5 hrs on the road. Both the driver side and passenger side were set at 71F and the fan was set on Auto Lo. I had to open my sun roof and drive for 30 minutes before I could get it to work again. The fan refuses to blow air at any setting, but the compressor seems to keep working because cool air seeps out of the vents. This is the first time I have had it happen after 12000 total miles. I'm bringing it to the dealer.

A/C Freeze-up

This problem has happened to me once during the past summer as we were driving in >30 degree Celcius heat for a duration of more than 2 hours. Once we parked the car (and presumably it thawed out) the problem corrected itself. After reading this thread, I brought the TSB to the attention of my dealer's service department. So far, I have been to the dealer a total of 3 times now. Each time they tried to flash the A/C module, they were unable to have their computer unit recognize my a/c module. This may the reason why some of the previous folks' problem was not corrected by the flash.

The service guys have, to date, spent 12 hours on-line, initially with DCX Canada nd then their US counterparts. The story I have received to date indicates that the A/C module for the SRT-8 is different than the 300C and there seems to be a software problem based on the flash program. The software engineers are working on the fix and have indicated that they hope to have the correct, updated program within 2 weeks. Before going again, I will ask them to attempt flashing one of their "spare" srt's before another visit.
