Hello everyone, i need some advice here for 03 BMW 325i :

WHen i turn on my AC, the driver AC vents blows cold air, but the passenger ones blows warm air. I have done a lot of research and i read i might need to replace the Heater valve, however, people whith the same issue have done it and not in all cases this have fixed the problem.

Any ideas on what is wrong and what needs to be replaced ?
