This user also had no luck with any replies.

my temp works, as well as fan speed but my vent selection does not. The selection light and everything changes just not the vents, no matter what its always on dash and feet.

im going to a wrecker tommorow to get some stuff with a friend for his car, woudl it be in my best interest to grab a control, or can i fix it?

 

that wasnt it. same problem, everything works except for vent selection. Whats next on my list to replace?

 

time to go under the dash and trace the cables. make sure they didn't fall out of the clips and are still connected to the actuators.

 

alrite ill go look thru my crx servic e manual

edit: my 1991 civic crx service only had the civic heater control in it which uses the cables where as my crx only uses the cables for the temp and the rest is electric. guess ill have to just go and look.

its fixed, there was a plug by my throttle pedal. I ran a steel braided line in from the engine bay right next to it for my oil pressure gauge, must have been pushing on the tab causing the plug to fall out.

Thanks :D
