HVAC
Control Assembly (2nd gen interior - '95-'99):
Remove
Fan Control:
Remove the two 1/4"
screws (I have no idea why these aren't metric like the rest
of the car) and remove the switch out the back of the HVAC
control panel.
Fan control switch:
Dismantle Fan Control:
Step 1: Remove the
curved switch. Just pull straight out.
Step 2: Remove
center retaining pin. Squeeze the two tabs together from
the top of the switch assembly (can use a small flathead
screwdriver, or some needle nose pliers) to release the pin.
Get ready to catch small parts!
Resulting parts:
-3 identical springs
-1 smaller spring
-plastic pin/clip
-ball bearing
-metal disk
-plastic disk/housing
-base with circuit
board
Reassemble Fan Control:
Step 1: Place 3
larger springs in the plastic disk. There are round
indentations for them. You do not need to place the
metal disk on the circuit base yet, despite it being there
in the picture.
Step 2: Place the
metal disk on top of the 3 springs. There are round
indentations for them on this disk as well. Also pay
attention, as there are notches in the metal disk that line
up with parts of the plastic disk.
Step 3: Place
smaller spring and ball bearing into the plastic disk, and
place the assembly onto the circuit base. There is
a hole in the side of the plastic disk the spring and ball
go into, as seen in the picture above. The spring goes
in first. You will have to hold them in place while
you carefully slide them onto the circuit base, with the
ball nesting into the notches as seen below.
Step 4: Insert the
retaining pin into the center of the plastic disk. It
should click into place.
Remove
AC and Recirculation Buttons
Step 1: Squeeze the
tabs on each side of the assembly. You can probably do
this with your fingers. If not, a good size flathead
screwdriver will make it an easy job.
Step 2: Slide out
the front of the HVAC control assembly.
AC/Recirc button
assembly:
Remove
AC and Recirculation Buttons
Step 1: Remove
light bulbs. Use a flathead screwdriver and turn the
bulb about a quarter turn.
Step 2: Remove the
rear face. Use a flathead screwdriver to gently pry the
tabs loose, and pull the rear face off, being careful of the
wiring harness pins. (Assembly propped up in pictures by a
screwdriver for better pictures)
Step 3: Remove the
buttons from the housing. Remove the two springs
from the back of the assembly. Then press in on the
buttons to start pushing the innards out of the housing.
Then as you can reach the base of the innards, pull it the
rest of the way out.
Step 4: Remove the
buttons. They just lift off. The button face can
be popped off with a small flathead screwdriver - there is a
tab on each side of the button. (shown resting on top
of the housing to keep carpet fuzz out of the lubricants on
the buttons)
Reassemble AC and Recirculation Buttons
Step 1: Place the
button assemblies on the base plate. Make sure the small
wire spring is resting in its track. If you hold the
switch down against the plate, you should be able to click
the button in and out properly to ensure the spring is
positioned correctly.
Step 2: Push the
parts into the housing.
Step 3: Place the
springs back on their posts on the back of the switches.
Step 4: Click the
rear back into place. Make sure the two springs seat on
the bumps on the back of the housing, and that you do not
bend any of the wiring harness tabs.
Remove
Slider Light Bulbs and Wiring
Step 1: Remove the
bulb sockets from the panel. Turn counter-clockways
about a quarter turn, then remove.
Step 2: Remove the
wires from the panel. Just pop them free from the two
clips along the bottom of the panel.
Step 3: Remove the
bulbs. They're tight, but they just pull straight out.
Dismantle Temperature & Vent Selector Sliders/Cable Controls
Step 1: Remove two
screws. 1/4" screws.
Step 2: Pull on
control face to pop slider knobs loose. Shouldn't take
too much force, and it's easier than trying to pull/pry on
the knobs themselves. At this point the whole control
face should come off.
Step 3: Dismantle
cable controls. The metal bars will free up if you line
them up with the center of the slider motion, and back
slightly (pay attention to the notch at the pivot point).
With the bar off, the plastic piece underneath will come
free (the one on the underside has to be rotated to one
extreme position to line it up with an opening and remove).
The piece the knob came off of will also lift off at this
point, but will probably stick in place because of
lubricant.
Reassemble Temperature & Vent Selector Sliders/Cable
Controls
Step 1: Reassemble
cable controls. For both the top and the bottom, place
the plastic pivot piece and plastic slider on first, then
the metal bar. The metal bar goes on with the slider
end having the silver springy piece away from the slider.
See picture below for which parts go on top and bottom.
Step 2: While
holding the cable controls together, slide the controls back
through the HVAC controls face. Reinstall the
knobs for the sliders to hold everything together.
Step 3: Reinstall 2
screws. 1/4" screws.
Disassemble HVAC controls face
Step 1: Use a
flathead screwdriver to pop 2 tabs on top free. Then
pull the face back from the face front.
Step 2: Pull the
clear plastic light diffuser loose.
