Hi guys
My heating in my e90 is playing up. I only get hot air on the left vents of the car. The right side is cold/cool even when heatings turned up to max. Occasionally I manage to get hot air on bot sides but 99% of the time it’s cold on the right vents of the car.

Anyone else experienced this or know what could be causing this?

any help or advise would be much appreciated

thanks

Yes, you will have either an air lock or a partially blocked heater core.
Try the auto bleed a couple of times first, if that fails then flush the heater core with a hose pipe.
Mine was exactly the same, only heat coming from drivers side, flushed the heater core, refilled with anti-freeze then bled the system and heater is working fine now.
Hey pal, thanks for the advise its much appreciated. Yeah i thought it could be a blocked heat core or the flaps that could have stuck. I'll get my mechanic to flush, fingers crossed it does the trick
