A/C problems & C230.. Getting Diagnostic Codes?
Hello!
I've recently been experiencing some problems with my '03 C230K.
The a/c has been blasting hot air every so often. Sometimes the temperature of the a/c will shift from cold to warm without me changing any settings, and the speed at which the a/c blows seems to fluctuate sometimes.
I brought my car into an a/c specialist to check if it just needed a recharge or top up, they said it was fine and that I would need to bring it into a garage that works specifically with mercedes because it's a sensor issue or an electrical issue.
I want to figure as much out by myself before I need to bring it in to be checked out because we all know how much that will cost..
Can anyone tell me the procedure on how to check the diagnostic codes specifically for my car model? I have the list of codes itself but I need to know which buttons to press in order to get them.
Or any other suggestions would be greatly appreciated.
Thanks!
