Defrost only?
I can only get air to come out the defroster. I can get under the dash and manual move the defrost actuator thing and it will go to the vents. I let go & defrost only. The vacum line to actuator is on. I replaced the actuator 1 yr ago. What else do I check?
Thanks CB

dont know about the 97, but check all the vaccumn lines. can you feel any suction at the line when you disconnect it.
I acidentally pulled a line loose installing gauges and all i could get was air out the defrost till i found the leak.trace the line out and check all connections.

Check all the vacuum lines along the firewall under the hood. I've knocked a connection loose working under the hood before (a couple of times). Also had a friend's truck where the line fell against the exhaust housing on the turbo and melted in two.

i removed the actuator and it operates fine with suction applied. Still no suction from the line that connects to it. I will track down the vacum line from under the hood.
Thanks

I found a hole in the vacum line right by the driver side battery. All seems to work fine now. Should only be few weeks until something else breaks.
