When AC is set to Max (recirculate) with blower on high air is ice cold but flow from dash vents is week. Sounds like something is blocking air flow and forcing it elsewhere to floor. The same problem occurs when heater air is set on dash vents. Any thoughts? Thanks.

Typically the air flow is controlled by vacuum motors connected to diverter doors in the duct system. ONe of yours might be broken or the vacuum lines disconnected or leaking. The vacuum control could also be defective.

Most likely a problem with the vacuum line. The line runs from the large vacuum line at the power brake booster to the firewall on the passenger side.
