Ok well i bought this 94 320s and I don't know if I'm working the a/c buttons right but i'm sure i am. On max and recirc and pushing the blue button on the middle vents, it feels like its not blowing hard. but you can tell the difference when you go to a lower speed on the knob. any ideas?

push the auto and recirc and it should be blowing high speed...if not....could be blower motor or resister...rotate the fan speed wheel....high to med to low and back to high....any changes? If not...see above.

you can tell the diff by rotating the knob. just on max is seems to blow at low speed. hopefully not too much to fix the problem

If it blows low on max setting....two things come to mind....blower motor or resister....
buy both and be done with it....if you replace only one....soon enought....the other part will need replacing and most shops will replace both anyway....they don't want you coming back for the same problem...ebay has blower motors and resisters....plan on at least a few hundred bucks...easy to change yourself. Very easy.
Unless the climate control switch is bad.....but very rarely do they go bad also.
