No heat up front - Blend Door actuator motor works

[DetroitDarin]

My mechanic - whom I trust - went to replace the blend door actuator in my 06 EB. He called to say the actuator worked fine - where should we go from here in our quest to get HEAT up front?

He checked the core, electrical, etc. - could it be a case where he didn't notice the 'thingy' had stripped where it connects to the blend door?

Please help!

Plugged heater core? Check to see if you have hot water going in and out of the core / heater hoses

Just because the actuator is working, does not mean the blend door is moving. Can you hear the door move and is so does it stay? My actuator would move, even move the door but once to took off from a stop, the door would slam shut and no ac. Maybe I was taking off from the stops too hard.

Thanks - he's going to have to remove the whole dash and check the doors, and entire assembly - whereas before he was working through the radio hole.

there is as blend door replacement that you go through the glove box. That is the one I used. It saves a lot of time and money.

Looks like a plugged heater core.
