My son has been mentioning the heater fan doesn't work. I have been faffing around with it a bit with the ignition on, I can't get it NOT to work?
Turns out it works fine with ignition on but not when the engine is running.
Going to clean the fuse holder when I get a chance, any other ideas?

Note that is an odd one, if switched on should go at all times the ignition is on regardless as you know.
All I can think is some one has wired it wrong at some time but just a guess.

The wiring looks stock and it's worked fine for years. I'm thinking must be a loose connection somewhere which might be affected by the vibration of the engine maybe.
Job for another day I think.
