[owain]

Looking for some help, my 1998 S320 has EC light on the ac control pannel. cant get light to go off & ac comp not coming on. working fine when put in the garage last night.

anything other than loss of gas that can cause this issue, do i need to take to MB dealer to have diag tool hooked up.

thanks for any help.

If you google it, you will find instructions on how to get and clear any fault codes in the A/C ecu, just by using the buttons on the unit in the dash.

here is for a w202, but I bet it's the same:

For whatever reason the ACC is not turning on the compressor. The EC light comes on, as though you had pushed it and the compressor is disabled. Low pressure is the usual cause. Don't suppose you took a rock to the condensor?
