The two center vents in my '94 Si every once in a while just don't work. I'll turn the A/C on one day and they will be fine, then I turn the A/C on the next day and the center ones won't blow out anything. There is no weird sounds or anything, but I don't feel like paying $66 for a diagnostic, so does anyone know whats up?
Thanks

 

Get under ur dash and center console and check the vent ducts.

 

its the contact points on the ac control unit ... they need to be re soldered... you can hit the dash like i do and it works usually

 

There is a writeup on how to do the soldering job. I think it is on preludeonline...

Pretty easy fix..

 

not to jacked the thread but somtimes when i turn on the lights the bottom climate control light wont stay on ...anybody had this problem
