Simon, yes, I will later...Mandrake wrote:I'd identify this circuit that allows low fan speed with the key off and start troubleshooting there. Can you post the full circuit diagram for the fans Jim for a looksee ?
It is interesting it has coincided with warmer weather but it's not that warm yet!!! I don't' yet know what triggers fan run-on but the fan diagram shows lots of unused inputs into the Bitron ECU which I presume are parts of the aircon diagram. I guess such an input comes from the aircon ECU via a sensor somewhere on the evaporator and this sensor may be the one telling lies and causing to odd behaviour.
I'll get those diagrams up when I can as I'd really appreciate your thoughts on this Simon
