i have a 97 without the climate control...just the fan switch, direction buttons and temp slider

i found that the direction buttons don't work...they click in and the little light comes on but the air is stuck in only coming out the dashboard vents...i'm not sure how long this has been going on cause just the other nite when it fainlly got cool i put on the heat to have the windows down and i wanted it to come out of the floor vents and it didn't

i installed a headunit a while ago and i'm not sure if this problem has been since or it just started recently...i was told that i might have messed up some vacuum tubes or something...

ANY help would be appreciated

thanks,
adrian

 

If I had to guess, I'd say that your problem is in the manual climate control headunit or you could have just not connected the wiring to the control unit properly when you installed your headunit.

I think you should re-check the connections to the manual climate control unit - make sure they're not loose, no damaged wires, etc.
