Why is my Vauxhall Zafira Life's heater not working properly?

I recently noticed that the heater in my Vauxhall Zafira Life is not working as well as it used to. The air coming out is not as hot as before, even when the engine is fully warmed up. What could be causing this issue and how can I fix it?

This could be due to a faulty heater core or a malfunctioning thermostat. It is best to bring your car to a certified mechanic for a proper diagnosis.

It could also be due to low coolant levels or a clogged radiator. Check these components and refill or clean as necessary.

Sometimes, air pockets can get trapped in the heating system and cause issues. Try bleeding the system to release any air bubbles.

It may also be a problem with the blower motor or its wiring. Have a professional inspect these components and replace if needed.
