How does one go about changing the light bulbs in the EATC unit? Only half of mine lights up, thanks.:D
Also, I may need to change the hose, that runs from the heater core to the EATC valve, but didn't see it listed at autozone. Anyone know which hose this would be listed as.

To fix the lighting.

Remove dash fascia (varies by model)
Remove 4 screws securing EATC module
Unplug 3 plugs from back (One is on the side for Rear Defrost)
Remove (2) 1/4" bolts from defrost plug
Remove (4) Phillips screws from housing. Two in bottom rear, Two in back side of the front lip
Slide rear housing off of EATC module

This is where things vary... If you'd like, just remove the two bulbs and replace (194 I think)

If you dont want to risk breaking the bayonet mount, and/or want to clean it while its out, read on.

Remove (5) black Phillips head screws, holding circuit board to the front panel
If you are JUST replacing the bulbs, pull them out and replace

If you want to clean the buttons, remove the (2) Phillips screws holding the light bar, and then tip the face over and the buttons will fall out.

While you have everything apart, if any of your buttons are getting hard work, try gently rubbing an eyeglasses slotted screw driver between the rectangular contacts, and the dimple that they connect with. You want to se any build up off of the dimple and metal contacts without damaging it. I have also used the end of a round tooth pick. You actually have to be pretty darn rough with it to break the metal contacts off of the board.

If anyone wants this done, but doesnt want to deal with it, or is worried about breaking something, pull you module, and ship it to me with $20 and return postage... I will fully clean, and replace lighting.

(I actually just did that all from memory...)

PS... Make sure you put your rear defrost switch back in the right way, or you will be really confused when you try to use it, and "ON" is towards the bottom (Squiggly arrows point up)
