Drivers Side Warm Air

[nvallettejr]

I’ve searched this forum up and down.... does anyone know why the drivers side AC would blow warm air and the passengers side piss cold in an ‘11 328i? Drivers side tarts to go slightly cool after running for a bit. Other BMWs with the same issue seem to go down a wormhole of issues before arriving at replace everything solutions. Just posting with the hope that someone else has some insight before I dive in the hood myself.

Just recently had the valve cover and gasket replaced late last year...praying it’s not the compressor and I’m just low on refrigerant.

First step to any A/C complaint is a proper recovery, evacuation, and recharge. The amount recovered will be measured by the A/C machine and you'll know right away if the system is low or not.

If one side is fully cold, the A/C is working. Sounds like a blend door problem. Have you pulled codes?

Not throwing any codes external codes. Good point I will have to check for stored codes.
