#175 of 181 Re: 98 C230 A/C problem [Mr_Shiftright] by lalabenz Aug 15, 2008 (8:01 pm)
Replying to: Mr_Shiftright (Aug 12, 2008 9:53 am) Thanks, Refrigerant levels and pressure are OK, the guy checked my refrigerant pressure first with some pump. Then he went to his office and looked over his computer and told me that it was common in Benz C230, some temp sensor went wrong and the AC will work for a few mins then shut off automatically after each engine start. Not sure if I should trust him or not. Replies to this message: Mr_Shiftright (Aug 16, 2008 7:58 am) lalabenz (Aug 16, 2008 8:32 am) Mr_Shiftright (Aug 16, 2008 8:52 am) and 1 more...

Replying to: lalabenz (Aug 15, 2008 8:01 pm) Not a matter of trust but he obviously doesn't want to tackle the job, so you'll have to shop around anyway. I wonder if he is referring to the ambient cabin temperature sensor, the one that tells your temperature control module that you've reached the temperature you dialed in?

Replying to: Mr_Shiftright (Aug 16, 2008 7:58 am) I think he talked about the one reading temperature. But he does not have the meter to confirm the sensor is bad or not. The sensor is beside the driver gas pedal, you can find it after removing the plastic vent.   But I doubt it, even I set the temp to LOW, which means the compressor should work no matter how cold the inside temp is, right?   Do you have any CD or experience about the problem, AC works for 1~2 mins after each engine starts. Thanks a lot. Replies to this message: Mr_Shiftright (Aug 16, 2008 8:52 am) lalabenz (Aug 16, 2008 1:53 pm)

Replying to: lalabenz (Aug 16, 2008 8:32 am) It's all just guessing. I'd have the codes read to see if there's any hints there, otherwise an AC specialist has to figure out what is shutting the AC compressor on and off and making it cycle. Could be ambient temperature, could be pressure switch, could be compressor losing pressure, dunno.   There is a Technical Service Bulletin on this problem although I don't know exactly what they are talking about:   Notes   Date: December 18, 2002   Order No.: P-B-83.55/65   Supersedes:   Group: 83 SUBJECT: Model 203, 211, 215, 220, 230   A/C Compressor Switches On Frequently   "If you encounter instances in the above models where the air conditioning compressor as well as the mirror heaters switch on with an increased frequency, replace the multifunction sensor for activated charcoal filter. The increased frequency of operation is a result of an incorrectly calibrated multifunction sensor sending erroneous values over the CAN bus." Replies to this message: lalabenz (Aug 16, 2008 1:53 pm)

Replying to: Mr_Shiftright (Aug 16, 2008 8:52 am) Thanks. My compressor seems only switch on when start, then shut off until next start. I just released all refrigerant and put 2 can of 134a in. the problem is still there.   A few months ago, it has been working for two days, but after that, the AC system just work one minute for each trip. During the trip, it never switched on and off, just off.

Just bought a 2006 C230. Car didn't come with a manual and I am trying to program the cars garage door opener located on the rear view mirror. Could someone please just give me the steps that are needed to do this. Thanks.

Replying to: lalabenz (Aug 12, 2008 9:03 am) I had similar problem. As it turned out, the heating/cooling system had never been calibrated.
