E90 dash heater problem

Apologies is this isn’t the place, it’s my first post. I have a 2008 E90, when I put the heater on, it only blows hot air into the passenger side, the driver side remains cool. I’ve replaced the thermostat, the water pump and radiator, I’ve also flushed and replaced the coolant and had the air con re-gassed, I’m running out of ideas now, any help would be appreciated.

There is a part called the heater resistor, also known as the hedgehog due to the way it looks. When this goes bad it can give similar symptoms also makes the heater pulse sometimes. Have a Google, this could be the problem. It's an easy fix and fairly cheap too
