2001 town & country ac - simple
 

The mechanic has disconnected something allowing the ac to work only in the rear vents, the front and middle vents no longer work. What could he have disconnected? It's hot!

no air or no cold air?

The rear vents blow cold air, the vents in the middle and front do not blow air at all.

When we took it to the mechanic all the vents were working, but on high only. Before picking it up, the mechanic tried to convince us to let him fix that, we told him we would return when we had the money, I believe he has disconnected something to ensure we return since it is so hot out and the air is needed.

he replace a blower motor resistor for only working on high 20 bucks in parts 10 min in repair look on the driver side by the gas pedal all the motors are over there see if one is unplugged.
