The heater on my '02 Mercedes Sprinter 316 is tepid at best! Even when I've driven for sometime it won't be hot. The garage failed to fix it...twice! Any ideas?
possibly the heater cont valve its on the bullkhead in the engine bay to the left of the engine the plug corrodes on it or it some times jams looks like small electric motor with three pipes attached.
