Cold air on passenger side
Pulled the heater valve today and cleaned it. Checked to see if the solenoids were working properly, they were. Ran the car and still cold air on passenger side.....Disconnected the wires to the heater core and drove it again but still cold air on the passenger side. By theory if there is no power to the heater valve solenoid I should be getting hot air....correct? Why would I only be getting hot air on the drivers side and cold air on the passengers side?
What does this flap do? Passengerside temperature mixing flap
Following my logic. Kind of scary huh??? Anyway I now believe the problem lies with the cold air flapper on the passenger side. My reasoning is that prior to this problem when ever I would turn off the blower motor I would hear a thump after about 60 seconds. It no longer does this. I now believe this was the cold air flapper on the passenger side, and it was on its way out. Question now, is it the stepper motor, the linkage rod between the stepper motor, or the flapper itself. I know I will have to remove the front console to access the stepper motor but will I have to disassemble the IHKA to repair a broken flapper. I have seen picture of these beast and it looks pretty scary.
I only have motor 1 and 3
I only have motor 1 and 3, then I have a cable controls where motor 2 should be.

Can I pull the dash and open the top of the vent tubing and access the flap from there? Without having to pull the IHKA out?

Yes there is a motor on the drivers side (USA) and a cable that actuates the fresh air vent on the passenger side but this is fresh air vents that are on the firewall. The vents that I am talking about are in the interior of the car. Looking at all of the pictures it appears that if the dash is removed you should be able to remove the top of the IHKA without removing it. But then again I may be talking about the duct work on top of the IHKA. I think if the duct work is removed I should be able to get a closer look at the flap and perhaps repair it. What do I have to loose I still have to remove the dash anyway :) Now its off to find instruction on dash removal.

Here is a pic of the arm. Not the white arm but the black one behind it. I circled it with a yellow line. I will pull the existing and see if I can make one. Now I wish I had a mill.

Plastic flap glued in place
Cleaned the shaft where the plastic flap broke off. Then spread some JB Weld along the broken edge of the flap, tried to make it a thin line just on the edge and the thickness of the plastic flap. Stayed away from the edge about 1/4" (see photo). Then I pushed the other flap closed in the other vent, this makes it easier to position the flap into place and gives it support on three of the four edges with the forth edge being the broken edge. Carefully place the broken flap into place making sure not to get glue anywhere except the break. Once the flap was in place I then smeared JBWeld along the broken seam. with a popsicle stick. Making sure not to get it too thick so it doesn't get on any other parts. That was about 2 hours ago, just went out to test it and it worked. Once it sets up over night I will apply JBWeld to the other side. I also spread JBWeld on the other flap, It has a couple of hair line cracks on it too. This is a tight area and my head was against the windshield and had to fight to get one eye into position to see down the hole :) Isn't the prettiest job with glue I have seen but if it works who cares ;)

The metal flap "above" has plastic button which is lying next to the flap, broken in two pieces. The rest of the broken button can be seen through the floor vent, it is an arm. So I will need to get the arm. Wonder if it is available?

The plastic flap "above" can be JB Welded back into place which I will do tonight Any suggestions before I proceed?????
