How do I Remove the Instrument Cluster on a Cadillac Deville Sedan?

by Robert Moore

The instrument cluster on your 2005 Cadillac Deville is secured to the instrument panel by several bolts that are hidden below the top dash pad. You don't need any special tools, but you do need a nut driver set and a flat-head screwdriver. The instrument cluster is programmed specifically to your vehicle, so you have to visit a dealer for programming, if you're replacing it with a new or used unit.

Removal

1

Push the rear seat lower cushion toward the rear of your Deville while lifting up on it. Disconnect the wiring for the heated seat elements, if equipped. Lift the seat cushion and remove it from your Deville. Loosen the negative battery cable bolt, using a battery wrench. Remove and isolate the cable from the battery. Wait five minutes for the air bag system to power down before continuing.

2

Grasp the windshield pillar trim panels and pull them off the windshield pillars. Wrap some masking tape around the tip of a flat-head screwdriver. Examine the forward-facing air vents and find the retainers in the upper-right and lower-left corners of each vent.

3

Pull outward on the vent while pushing in on the retainers with the flat-head screwdriver. Remove all of the forward-facing vents. They are not interchangeable, so make a note of where each one belongs in the instrument panel.

4

Pry upward around the edges of the defroster grille to release the retainers. Lift upward on the rear edge of the grille, then disconnect the wiring harness for the sun sensor, if equipped. Pull the grille rearward and remove it from the instrument panel.

5

Remove the four screws that were hidden by the forward facing vents, using a nut driver. Remove the three screws hidden by the defroster grille. Lift the dash and tilt it so that it is parallel with the windshield. Disconnect any wiring harness connectors, then slide the pad rearward and remove it.

6

Remove the screw that secures the instrument cluster trim to the passenger-side trim. Remove the screws from the outside edge of the trim panel. Disconnect the wiring harness connectors, then remove the trim panel.

7

Remove the instrument cluster screws and pull the cluster rearward enough to access the wiring harness connectors. Disconnect the connectors, then remove the instrument cluster.

Installation

1

Reconnect all wiring harnesses as you go. Position the instrument cluster in the instrument panel. Install the retaining screws and torque them to 14 inch-pounds with an inch-pounds torque wrench. Install the instrument cluster trim panel and screws. Torque the screws to 18 inch-pounds.

2

Align the dash pad with the instrument cluster. Slide the panel forward. Align the rear edge of the pad with instrument panel trim, then press down to engage the retainers. Install the dash pad screws and torque them to 18 inch-pounds.

3

Align each of the forward-facing air vents with their respective holes in the instrument panel. Push the vents into the panel until the retainers engage. Guide the forward edge of the defrost grille into position, then lower, and press fit the rear edge of the grille.

4

Press fit the trim panels to the windshield pillars. Connect the negative battery cable to the battery. Tighten the nut to 13 foot-pounds. Guide the rear of the seat position. Connect the wiring harness to the seat heater element, if equipped. Lower the seat, then push down and toward the rear of your Deville to engage the retainers.

5

Drive to your local dealership to have the instrument cluster programmed to your Deville if you replaced it.
