I noticed today that air is not blowing through the dash vents, even with the ECC saying that it should be. I noticed some other posts that said somthing about a motor that may need to be replaced in the dash. My AC is temporarly disconnected, but I should still be able to have air passing through the vents on Econ right?

Which vents Mike, I know on my 90 I only get heat out of top and floor, A/C will come from middle and top and floor.So the only tome it comes out of mid is when A/C is on and was told that is normal .Terrible design.If yours did work like you were saying and doesnt now then yes under passenger side hush panel is your HVAC programmer and door actuator.You should be able to look up and see the actuator arm move the door flapper when you change vents on your controls maybe this has failed.The motor you are talking about is in the black casing you will see about 4 different color vac air lines going into it.If one of these lines is disconnected or not getting vacuum air thru it wont give the signal for the actuator to open that vent IIRC.

Its allways a good start to remove the HVAC control and clean the connector.

John- I think that it is the motor as the arm does not move at all, and I don't hear a small popping sounding anymore. I had a spare unit from my 89- but it looks to have been thrown out.
SSE- I have another ECC unit that I will try tonight- and I'll clean the conectors too.

thanks guys

Mike the motor for that arm is in the black HVAC casing,soon as you pull down the hush panel you will see HAVC programmer there is a little motor inside.
Of course after you clean all your connects

The motors do tend to stick on some cars. had to give mine a push a couple times to get it going.

Its definitly the motor. Mine does not move at all. changed the ECC and it still does not work. I'll have to go to the yard....
