Center vents only open for A/C or cold air. If you turn to full cold then the pod that controls that door has gone bad or the dial has it closed off.

My 97 dodge ram has no air coming from ac/heat vents in dash except for the top vents next to windshield. no air coming out at all of any kind all across front of dash.


Your ac blower doors that direct the air to the vents are vaccum controlled check your vaccum lines going to the ac most of the time it is a leak near the vaccum check valve. The reason it is only top vents is because it is the default setting in the system

My blower motor works but is not blowing out the vents on dashboard, only vents by windshield and side vents but not from dash...how should this be fixed....some vacuum hose ??


You have a loss of vacuum from the engine, first check under the hood and make sure the vacuum storage tank is not damaged and leaking and it has vacuum in it when the engine is running. If all that is ok then move on to the line that goes inside the truck and verify it has vacuum.
