BMW: e34 ac, cold air blows, e34 m50

Question
Hi Bruno,

I drive a 1991 e34 M50.

When i put on the AC on the climat control, the cold air blows from the passenger site and the side vents and even the back but it doesnt blow on the drivers side.

Please wat could be the cause and how can this be rectified.

Thanks.


Answer
Sounds like the driver side vent valve is not opening... it is a mechanical plastic piece that opens and closes as you turn the dial on your AC Controls... You will have to take apart the driverside vent and see if anything is keeping it from going to the open position when the knob is turned on the cilmate controls... if still no luck you will need to take out the dash board and trace the cable (looks like a bicycle brake cable) from the dials to the valve on the driverside ac vent.

Hope this helps,
Emanuel
