What are common technical issues in the Ford Galaxy?

I recently bought a used Ford Galaxy and I'm experiencing some technical issues. Some of them include the car's engine making strange noises and the air conditioning system not working properly. Can anyone offer some advice on how to fix these issues?

It sounds like you may have a problem with the engine's spark plugs. I would recommend taking your car to a trusted mechanic and having them check the spark plugs and the ignition system.

For the air conditioning issue, I would suggest checking the refrigerant levels and the compressor. If they are both in good condition, then it may be an issue with the air conditioning relay.

Another common issue with the Ford Galaxy is electrical problems. It's important to regularly check your car's electrical system and make sure all connections are secure.
