the heater is really a bit strange on my 323 auto, it has the dual zone climate control.
it gos like this...
when i set off in the morning i set the climate an 22 degrees. (with the aircon off) the car heats up nicely just as you would expect. but then in about half an hr, the heat start to go cold. so i turn it up to 30 to get it back to warm. it then heats up again. obviously this is way out because there is no way its actually 30 degrees.
when the car is left to cool down the process will start again.
i have removed the pollen filter from car. the same thing happens regardless of the aircon being off or on.
anyone have any ideas? thermostat maybe?
