ok so heater and ac work right but it will only blow out the front vents or the windshield. what do i need to check or replace? this is on a 98 civic hx.

 

Here are some tests to do:

 

ok so is this up under the dash on the passenger side?

 

This may help:

 

nice. thx ron. this really helps. if that mode control thing is bad how much is it to replace?

 

Cheap if you scout junk yards. More at Majestic Honda or your local Honda dealership.

 

thx again ron. went to the junk yard and picked up 3 motors. the first one i tried worked and fixed my problem. gonna test the others later to see if they work. they look brand new. only spent 15 bucks on all 3 of them. 155 bucks at the dealership.
