Heater problems

I am hoping someone has a solution. My heater air con is working fine on manual and auto. However I cant get any air out of any of the ducts, other than a trickle. The fan runs fine at all sppeds and reacts to a change in temperature but moving the air outlet dial makes no diffrence as to where the air comes out. I hear noises from the dash as though the flaps etc are moving but nothing. Has anyone expierienced the same?

If the air is coming out the defroster on the dash then you have a vacuum leak. If it is not doing that, then you have the normal blending door issue. which means you need to pull the dash to fix all the doors in your HVAC system.

Just a mild flow from all areas irrespective of control positioning, so assume the latter. Time consuming I am sure but is it an expensive repair?

I have heard the cost is between $800 and $1200 and it takes about 8 hrs to do the job.

^^^^thats assuming your dealer does it for you, it's a fraction of the cost to DIY

it's not that expensive to fix, it'll just take you a full day of pulling the dash

http://www.wjjeeps.com/hvac_sub_assembly.htm has all the parts and a good outline of how to go about it

It does cost that much--because of the labor involved. I'm about to drop that kind of money on my Jeep to have the heater core replaced.
