I've recently noticed the speed at which air blows out of the heater can be a bit variable, If I turn it on at 4 or 3 you can hear the blower speed up and slow down a little. Driving into work this morning I had the blower working but then it cut out and stopped working so I switched off the blower to be on the safe side. Parked up and turned it on again and it was working fine.
Is this the Heater Card starting to go? Really not the weather to have no heater or blower for demisting the windows....
