Problems with climate control?
I know that my outside temperature probe needs replacing but I don't know if it has anything to do with a new problem I have found.
When I turn off my climate control the led on the off button comes on but the fan blasts heat into the car. Just as if I set it on max heat. I was wondering if anyone has come across this before?
Thanks,
ElD

Just so I'm clear, you are turning the whole HVAC off, or just the AC part? If you turn the AC part off, it's normal for it to crank the fan, to try to cool off the cabin. IT doesn't seem to know that it's blowing warm air, my cars do the same thing..

Oh. Well, sounds a lot like the fan controller is wonky, but it could be the resistor pack. On the fan itself there is a resistor pack that controls the speed of the fan. Basically any speed OTHER THAN full blast is controlled by that resistor. So when you turn off the HVAC, something is feeding the fan voltage (obviously.).
could be a pinched wire, could be a bad fan control module.. could be more..
