I finally got the heater mode door fixed. It turned out the motor was fine. What happened though was one of the levers that was attached to the motor was hitting the plastic case it was mounted to and getting stuck. I filled away the part it was hitting and it works great. I hope this can help anyone else who is having the same problem. Before replacing the motor make sure it isn't getting stuck.

It is definitely the Heater mode door actuator motor. It is not able to move the levers to change the air flow. I took the motor off and the levers freely move when not connected to the motor. Now I just have to find a new motor to install. Thanks for the help.

Does anyone have an idea of where I could get info on how to replace the resistor in the wiring harness of the heater mode door actuator?

I just searched for info because I think you guessed it right and sure enough. Consumer Reports said that one problem of the 92-94 Legacys is that there is a clicking noise caused by the heater mode door actuator. They said it can be fixed by installing a new resistor in the wiring harness. I am going to try that out and see what happens.

Hi, This is my first post and I just bought a 93 Legacy. One thing it does is that when I push the off, bilevel, heat, or defrost bottons a clicking noise begins and the vents continue to only blow out of the dash. I looked in the dash and the clicking seems to be coming from the heater assembly. Any ideas what is wrong. Thanks.
