Part 1 - Instrument panel assembly removal
NOTE: Before starting this procedure, be certain to turn the steering wheel until the front wheels are in the straight-ahead position.
WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN AN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
1. Disconnect and isolate the battery negative cable.
2. Remove the trim from the right and left A-pillars (Fig. 1).
5. Remove the scuff plates from the right and left front door sills. These are attached with spring clips and can be removed grasping them underneath a corner and carefully lifting them up.
6. Remove the lower trim panels from the right and left inner cowl sides by removing the screws attaching cowl trim to floor. Remove plastic nut. Grasp cowl trim and pull outward to separate from clip.
7. Remove the console from the floor panel transmission tunnel (Fig. 4 & 5).
9. Remove the cluster bezel. The cluster bezel lower trim piece is held in place by 4 spring clips, one at each corner. Pull straight out to remove. On the left side, you can reach your thumb behind the bezel at the tilt wheel lever indentation and pull forward. If so equipped, you'll need to unhook the Adjustable Pedals harness from the back of the bezel. (Fig. 6 & 7)
14. Disconnect the instrument panel wire harness connectors from the following steering column components (Fig. 25):
15. Turn the ignition switch to the On position, then release and remove the shifter interlock cable connector from the ignition lock housing receptacle.
16. Turn the ignition switch back to the Lock position to prevent steering wheel rotation and the loss of clockspring centering following steering column removal.
17. Remove the bolt that secures the coupler to the lower steering column shaft (Fig. 26).
19. Remove the steering column from the instrument panel. Be certain that the steering wheel is locked and secured from rotation to prevent the loss of clockspring centering.
20. Disconnect the left and right body wire harness connectors, the ignition off draw (IOD) wire harness connector and the fused B(+) wire harness connector from the connector receptacles of the JB (Fig. 27).
21. Disconnect the instrument panel wire harness connectors from the following floor panel transmission tunnel components (Fig. 28):
22. Remove the two nuts that secure the instrument panel wire harness ground eyelets to the studs on the floor panel transmission tunnel in front of and behind the ACM.
24. Remove the instrument panel to center floor tunnel bracket from the instrument panel and the floor panel transmission tunnel (Fig. 21).
26. If the vehicle is equipped with the manual heating and air conditioning system, disconnect the vacuum harness connector located near the driver side of the floor panel transmission tunnel behind the driver side floor duct.
27. Remove the one screw that secures the instrument panel steering column support bracket to the driver side end of the heater and air conditioner housing (Fig. 29).
28. Remove the one screw that secures the instrument panel steering column support bracket to the intermediate bracket on the driver side dash panel (Fig. 30).
(On earlier models there is a steel bracket between these two pieces as in the picture. Removing the nut wont let the support bracket loose, you need to leave the nut and remove the bolt from the steel bracket to the back of the support bracket).
30. Remove the nut and disconnect the safety strap from the support bracket (Fig. 32).
32. Remove the end cap (Fig. 20).
34. Remove the glove box.
35. Disconnect the instrument panel wire harness connector from the lower cavity of the inline connector on the passenger side cowl side inner panel (Fig. 34).
37. Disconnect the two instrument panel wire harness connectors from the two heater and air conditioner housing connectors located near the blower motor on the passenger side end of the housing (Fig. 35).
38. Remove the two screws that secure the passenger side instrument panel structural duct to the heater and air conditioner housing (Fig. 36).
40. Depress the tab on the passenger side and with the aid of an assistant, lift the instrument panel assembly upward off of the studs on the dash panel near the windshield fence line and pull the instrument panel rearward from the dash panel and the cowl side inner panels and remove it through the driver side front door of the vehicle (Fig. 38).
