Not 100% sure but I believe 94-96 would be the same.
1)Disconnect battery
2)Remove fuse panel cover (passenger side)
3)Remove side panel 3 bolts see fig A

4)Gently pry off air outlet cover see fig b
5)Remove outer air outlet 2 torx screws see fig c
6)Remove lower trim panel 3 nuts on top see fig d1 2 bolts on side see fig d2
7)Remove foam insert see fig e
8)Remove knee bolster 4 10mm bolts see fig f
9)Blend door location see fig G
10)remove 3 bolts wiggle and pull straight down.

 

 

Hope this makes sense anyway this is what the motor looks like

 

Thanks for sharing!!


What is the symptoms of failed motor ?

 

On my 95, a/c never blew cold. Once the engine was up to full temp, only hot air came out of ducts.
A quick way to check function of the blender motor is to get a visual on the blender flap/door. To do this, remove the diode looking thing on top of the heater box, which is on the starboard side of the underhood firewall, just toward midline of the coolant pressure tank. This will allow you to look down into the heater/a/c blender box. The door that the a/c /heater door/flapper is easily visualized. With the engine at an idle, and up to running temp, change the temp setting on the vehicle from hot to cold and see if the door moves it's position. If the motor is bad, the blender flapper/door will not reposition.
The base problem is that the motor sits at the lowest point of the heater / blender box, and moisture tends to drain into it. The assembly gets soaked and corrodes the electric motor.
The good news is that the motor is available at Auto Value parts stores for less than $125. Bad news is you have to stand on your head, beneath the passenger side footwell to replace it.
I used a couple bits of butyl tape to hold the new unit in position under the dash to get the screws started when installing the new unit.
My car had the digital climate control. Could be different if your's is something other, but don't know for sure. Best wishes.

 

Great info ,thanks for your time. I got digital climate control

 

Mine also has the digital climate control I had to open the flap manually under the hood to one side for heat and the other side for cold you can also run the climate control codes as well.

 

 

I replaced my blend door actuator yesterday and wanted to add some of my pics to this thread to possibly help with diagnosis. By the way mine did not throw any codes. I thought a failed blend door actuator might give a 01 or 02.

If you removed the 3 7mm bolts on this thing it will come out:




You can then shine a light down this "sight window" and see the blend door very clearly. The blend door is on the left of this picture


Then I put my phone down into the box to snap a better pic of the blend door:


If you have the blower running and cycle the temperature from hot to cold the blend door should open and close and if it does not then the problem might be the actuator. Here is mine once it was out. It did have a little bit of water in it


and opened up. It was completely shot the motor wouldn't run even with 12v to it directly

 

With the colder weather here thought I would give this a bump for anyone who has been putting off this project

 

Do you know if it is located in the same place on a '91?

If you have the opposite condition, i.e. Always get cold air, can't get warm air, could this motor be the problem?

 

It's in the same location on all C4s.

Always cold or always hot are both symptoms of the problem.

 

I just skimmed all the post, good job with the pictures, just wanted to add, try to install the motor with the blend door in the position the motor will be in when it is installed. Going by memory you can take the capacitor cap off over the front heater box housing and move the door manually to the correct position.

 

The HVAC system will recalibrate the blend door automatically. You need to remove power from the HVAC controller (usually by removing the CTSY/CLK (or its equivalent) fuse). It will recalibrate when the ignition is turned on the next time. It does this by moving the blend door to the full cold and full heat position and taking note of the door position at both extremes.

 

where can i get one like this one? the part # brings up one that is different and will not fit?

 

I know this was a while ago, but did you have to remove the seats ?

 

removing seat mades it easier to work on

 

one more question, is figure g the blend door itself?

 

FYI, the blend door actuator is only $38 on Rockauto.

 

No need to remove the seat
