Last year, I only got heat on the drivers side. I replaced the blend door actuator. While I had the old one out, I did check that the blend doors moved freely and easily. Worked all summer.

Now having the same problem. I checked all modes, they are working. Fan works. I don’t know if I bought an aftermarket blend door actuator or a Delco but I did order a Delco this time. I have heard that some aftermarket actuators don’t last.

Is there anything I may have overlooked here? BTW, there was some clicking just before it quit working.
