The gears are stripped in this actuator. It is very expensive to replace. $90.00 on-line or $160.00 from the dealer. Blend door actuators only run $20.00 to $40.00 depending on source. The only difference I can see is the recirc actuator has a lever on it. The rest of the unit looks identical. Does anyone know if the internal gears are the same. I would think that I could take the guts out of a blend door actuator and repair my recirc unit. Has anyone tried it? It would save a bunch of cash if it works.
