Air conditioning stops working when car started

I am new to my 89 420 SEL and this week is the first time I've opted to attempt to use the air.

When I turn my key to the "run" position but it is not on there is air blowing out of the vents. But when I turn the car on (the engine is running) this stops, and there is no air coming out of the vents.

Is there something to fix this? none of the fuses are blown.

I just had the transmission repaired. I am pretty sure the heat/ normal air flow was working when I dropped the car off.

Any suggestions?
