I have just discovered a wet patch on my drivers floor well (isn't water, more like coolant) Spotted a leak from the pipe that runs up to the heater matrix. Seems to be coming from the leaver that moves the heater controls. Dripping when the engine is running
Can anyone please suggest a solution?
Will it need a new pipe front to back?
Could I do away with that lever section as I've never used the heaters in the 3 years it's been on the road?
Any thoughts appreciated. Cheers, Jon.
The dripping is circled. Looks to be coming from the arrow point.
