I'm using 1993 220E with 140000 km in Thailand. The air-conditioning system only run well in the morning when I first start the car. It have worked only sometimes in the afternoon, depending on my luck. Also, when it's raining, the a/c completely stops to blow a cold air although before that it worked fine. I went to a shop, the technician said the freon pressure is normal and he suspected the failure of the a/c controller. Is there anything wrong with it?
Thanks in advance.
