Ok, i am using Olive daily at the moment and went out last night came home late, i was Blue!! ....... Can anyone tell me how to get the heater working in her!! -- I have cold air bellowing out on the windscreen i have moved the heater control things up and down no differance..... Still COLD air only
check the heater leaver is moving the cable and that the cable move the leavers on the heat exchangers under the van by the gearbox Then check the pipework from front to back for leaks
If youve got cold air blowing on the screen is this when your moving or is it all the time when the engine is running. Sounds like your fresh air vents are open. Not a good start. Sort this before moving on to getting your heating working. Let us know and sure we can talk you though what required (also lots of resources on line to explain how it works!) try this: http://www.ratwell.com/technical/Heating.html
If the blue lever (up) doesn't stop the cold draught, out with your screwdriver, whip off the front grill and investigate/push the flaps shut. I had to do this and also pulled off the cold air lever from the dash for good measure.
