Procedure:
Step 1:
Remove the passenger side carpeted trim along
the console.
There is one screw in the front you have to take out and then gently pull to
snap the clips out. Slide the trim to the front and work it out of it's
place. Once the trim piece is free, unplug the hidden 12V outlet and set this to
the side. The inside of the trim piece is a reverse image of this:
Step 2: Remove the hard plastic trim
piece that is below the glove box by removing the two twist nuts and the one
screw. Once the piece is free, carefully disconnect the interior light and
set the trim piece aside.
Step 3:
Remove the glove box. Open the
glove box and remove the 4 horizontal screws that go across the top of
the glove box opening. Next remove the pin that holds the plunger on
the left side. Next gently press in on the stopper on the right side
of the glove box to allow it to drop to a lower position so that you
can remove the vertical screws that are on each side of the glove box
opening (one on each side). Carefully remove the glove box from the
opening. Once it it free, disconnect the wire to the flashlight and
the wire to the glove box light and set the glove box aside.
Step 4: Carefully pop
off the plastic heating duct and set it aside.
Step 5: Locate the
final stage resistor unit.
Step 6: Press in the
lock tabs and unplug the
cable that goes to the final stage resistor unit. It looks like this:
Step 7: Once the cable
is unplugged, push down the lock tab that is on the lower side of the Final
Stage Resistor and carefully wiggle it out.
Here is what the Final stage
resistor looks like. The old one is on the left and the new one is on the
right.
Step 8: Gently slide
the new Final Stage Resistor into place, making sure that the lower locking tab
snaps into place.
Step 9. Reconnect the
cable back onto the Final Stage Resistor and do a quick check that the system is
now working properly.
Step 10. Once you have
verified that everything is working normally, follow the steps in reverse order
to put everything back together.
