Vauxhal Zafira 1.6 Club Petrol - Heater Problems - happyhotspur

My heater does not seem to give out much heat, I have checked out the LED reading as the car does not have any temperature gauge fitted, by pressing the settings button waiting for the bleep then pressing the BC button and scrolling through until I come to an LED readout which gives a temperature reading, that I assume is the water temperature, the car never goes above 30 to 45 degrees, (this is only after a 35 min motorwary drive) if this is the water it seems low to me hence no great heat, the blower is working fine, so what could be the problem?

Does anybody know what the usual temperature of the water should be?

Unless of course the heater in these car's are just crap!

Zafira heaters are usually very good. Your coolant is far too cool at 45deg. I think the first job is to replace the thermostat, which has probably failed in the open position. You should be running at 80+ deg at least.

The other thing to look at is a blocked pollen filter - behind glovebox. Changing mine last January doubled the heat output through the vents.
