How can I fix the heating in my Vauxhall Zafira Life?

My Vauxhall Zafira Life is not producing enough heat during the winter. What could be causing this and how can I fix it?

Firstly, check that the coolant levels are topped up. If they are low, fill them up with a 50/50 mixture of coolant and water.

Another common issue is a malfunctioning thermostat. It may need to be replaced if it is not opening and closing properly.

If the heater fan is not working, it could be a blown fuse or a faulty fan motor. Check the fuse first and if it looks damaged, replace it.

You may also want to check the temperature control knob in the cabin. It could be stuck or broken, preventing proper heat regulation.
