Re: mode switch diaphram disassembly & reassembly instructions??

["ksgrimsr" <knut.s.grimsrud@xxxx>]

I've had my mode switch out several times and it's pretty simple (at 
the time I didn't know what lubricant was suitable and I therefore 
had it out once for each lubricant I tried).

Pull the knobs off the controls on the A/C panel and remove the 
screw in the center that keeps the plastic bezel in place. Do not 
remove the screw holding the mode switch to the mounting plate yet.

>From the driver's footwell, reach around the edge of the console 
with your left hand/arm and grab the rubber boot/manifold attached 
to the rear of the mode switch. Do not disconnect any vacum hoses 
from the rubber boot/manifold. The rubber boot/manifold has a 
tactile index mark on it (a bump cast in the rubber you can feel 
with your fingers). Feel the boot and become familiar with its 
orientation. Unless you're some contortionist, you have to do this 
by feel since you cannot in general see anything with you arm back 
there, and you'll have to put it back on by feel later.

Pull the entire rubber boot with hoses attached off the back of the 
mode switch.

Now remove the screw securing the mode switch to the center console.

Leave the electrical connections at the bottom of the mode switch 
attached for the time being. They have a bit of slack that you can 
make use of. Work the switch with electrical wires still connected 
as far out of the cavity as you can. They should almost make it to 
the edge of the console. Now take a look at the electrical 
connections and make note of which colored wires attach to what 
terminal. Then disconnect the electrical connections and withdraw 
the mode switch.

Installation is the reverse of the removal procedure. Attach the 
electrical connections using the available slack and then mount the 
mode switch to the console. Reach back and grab the rubber boot and 
orient it based on the tactile features on it before pushing it onto 
the back of the mode switch.

The lubricant I had really good success with was silicone spray 
lubricant.
