I doubt that. Not too familiar on your year, but I thought that the vent selector was a mechanical switch. Anybody else?

Where the air blows out is controlled by a vacuum operated blend door. In the engine compartment, on passenger side of the fire wall, is a round black ball (vacuum canister). Make sure there is a vacuum hose connected to the ball, and if there is make sure it is connected to something on the other end.

everything is hooked up and workin now
was a loose vacum in engine bay
near the brake pedal is a t fitting one end runs into enine bay and the hose coming through the firewall is more like the hard airshock line going into regular like vacum hose
is this hard plasting tubing stock or someone been into it?
