BMW Repair: 01 325i passenger side ac blows warm, side ac, electronic issue

Question
Hi Don, The passenger side ac blows only warm air. The driver side takes
about 10 min to cool down and never gets really cold like it used to. I know
absolutely nothing about cars and don't want to get clobbered at the garage.
Seems like it could just need a recharge or maybe there's a leak? Or maybe
it's an electronic issue...  any ideas? Appreciate any feedback!

Answer
Well the a/c is one unit so your problem probably isn't a total lack of freon but you do have a blending problem.A door in the plenum is sticking or not working at all.It maybe an electrical issue so check all the grounds under the dash.Getting a manual from Bentley will help with the heater bow.
