Heater blower
 

Heater not blowing at full strength. The blower is on and pushing air but at times, it seems like it blast more air then decreases to a lower flow. It never turns off but something is lowering the flow of air. Any ideas?

Blower motor regulator.You can do some search on the forum and you will find many threads about that.

You can adjust the strength when you press the air flow button ( not the fan speed )make sure you adjust the heat (red) to the max with iDrive dial. Hope this help, I had the same problem before lots of air when in cool but not hot.

Thanks guys! Probably the regulator. I think I saw a thread about it. It's located under the passenger side dash. I think it's easy to get to? Who knows. I'll see what the dealer wants for the part.

I tried the settings in idrive and it's not it!
