hey guys I'm kind of new to this site so bare with me. I have a 99 honda accord lx sedan and I am having a problem with my a/c. the problem is that it is not blowing any air through the dash vents and the passenger vent. it only blows through the driver vent, the floor vent and also the windshield defroster vent. is there any way anyone can help me out. They have told me that it could be that the vent doors aren't opening but i just dont know how to go about that and fix it.

 

Does air direction change at all when you select different vent options?

If not, the mode control motor may have failed.

Venting from only the driver's side suggests the Center and Pax side vent ducts are disconnected. However it may be that venting through the floor and defrost is simply bleeding all the air to those vents. Again mode control motor should be checked.

You will need a shop manual for diagrams and help. Suggest purchasing an emanual from automanualsource.com, cost is $21.99.

good luck
