Hi, i think i have a vacuum leak in my vs. The heater wont come on, i checked the heater switch in the engine bay that tested good. I think the leak is behind the cold to hot switch. Has anyone found a easy way to find a leak cause i dont think oil or wd spray will help find it. Cheers

First check the bellcrank thing down near where your left foot rests when driving - it gets knocked off its mount and makes the hot/cold dial inoperative. Its just behind the plastic transmission hump cover about 200mm above where your left heel rests. This controls the vacuum to the heater switch. Apologies for my description which is pretty vague but I hope you understand.
