I have just reactivated by Frigiking A/C system on my 1965 230 SL. This took some doing and was after a new blower, new compressor, R-134 conversion, new expansion valve and receiver. The A/C works fine and cools nicely in the cabin. Problem that I've discovered is that the water condensate leaks into the car.
Looking at the drain tubing that goes to the drainage outlet through the firewall, it appears that there is a vertical rise that the drainage needs to overcome and thus the leakage inside. Has anyone seen this before and what fix would you recommend?
My Euro mechanic is recommending cutting a new drainage hole in the passenger floor panel to correct this.
Regards and thanks,
