follow up to defrost -- thanks jo and tiger

I finally checked out that vacuum valve for defrost. it does hold vacuum. it will move if I apply vacuum to it. started the car and switched to defrost then back. there is no vacuum on either of the two vacuum lines that attach to this valve. - with the car running. what could cause this??


Check for vacuum at the firewall... the yellow checkvalve... make sure you got vacuum there.
