Answerremoval of a dash is not for the faint of heart! Take your time!
Here are some tips
Remove your seats--you will need the room
Remove your steering wheel
remove your center console--, take out your
radio first
If you have a telescoping steering column, fully extend the column, then...
DISCONNECT THE BATTERY!
Here is the step by step as told by one of my friends
remove the kick valences on driver and passenger sides
Remove metal crash tube/ducting from above the driver's footwell. Remove stiffening brace from drivers footwell and disconnect wiring in the footwell.
Disconnect bowden cable from footwell flap.
Remove support bolts and allow steering column to drop down.
Remove speaker grilles and the cap head screws from speaker boxes on the right and left sides.
Remove the instrument cluster.
Remove the cap head screw in the center of the dash, between the defrost vents. This screw is underneath a plastic trim and the trim may be quite fragile. To remove it, reach in the opening for the instrument cluster and to the left of the support screw, you should be able to feel the tab on the plastic trim where it sticks down through the dash. Push it up and inwards to release. Be careful! There are plenty of sharp edges to be cut by in that dash...
Remove 10mm nut from lower attachment/adjustment points on the left and right sides of the dash
Remove radio and pull CCU panel. The CCU will be in the way so, you'll need to remove it completely. Next, remove the two screws directly above the CCU panel that attach the dash to the console. And, with the long phillips screwdriver, go in through the center venetian blind vent and unscrew the actuator arm from the center vent flap
Use a plastic wedge to pry off the light switch knob and a 24mm socket to remove the bezel retainer nut. Then, remove the light switch bezel. While you are over here, disconnect the parking brake release chain.
Now, reach in through the instrument cluster void and remove the electrical connector from the light switch. To remove the switch from the dash, twist the switch housing CCW to release the retaining tabs and pull it forward (toward the front of the car).
Remove a-pillar covers.
At the a-pillar, and use a plastic wedge to gently push the door welting outwards from the pillar. This exposes the outer edge of the a-pillar cover. Start about 2" above the bottom of the cover and use the wedge to pry the cover loose from the a-pillar. The cover is held in place by two metal clips: one is about 2" from the bottom, the other about 2" from the top.
To remove the cover, move the bottom of the cover towards the center of the car and downwards.
Make sure to put the welting back in place before you close the door
As far as the sun roof relay -- There is no relay, the switch is connected directly to the sunroof motor assembly. If the electric motor runs when you activate the switch then your problem is mechanical, not electrical. It's possible you have a problem with the motor assembly, they have been known to fail. If the motor runs all the time then the switch is stuck ;if on the other hand you hear it running when you activate it and the roof does not move then the clutches are most likely slippimg it the mechanism in rear of car and can sometimes be adjusted by turning the the outer nut clockwise a round or less
