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!

try re-syncing the stepper motors 1st

with the key on but ac/heat off

press and hold the defrost(for the windshield) and recirc buttons they system with cycle on you can let go and it should try every setting for approx 30 seconds then stop if it dose not stop you have a problem

Hey thanks I'll try this later and update how it turns out.

Would you happen to know what sort of problem it would be if it doesn't stop? A sensor issue or maybe something else?

Thanks
