The PT Cruiser's dashboard is made of numerous panels of different shapes and sizes. There are panels that make up the sides and the centre of the dash as well as one large top cover. The difficulty of removing each panel varies, and you will need to remove some before you can get to others.
Center Trim Bezel
The centre trim bezel surrounds many of the instrument panel controls. You should remove it first to help access other panels. Disconnect the knobs for the heater and air conditioner controls. Detach the controls for the power windows that are located in between the centre vents--pry the small panel off with a flat-bladed tool and then disconnect the electrical connector. Remove the single screw behind the window controls and then carefully pry around the bezel's edges to remove it.
Other Individual Trim Pieces
The knee bolster is beneath the steering column, and you'll need to remove it to remove the left side end cover. Grasp the bolster at the top edge, pull it back sharply and then rotate it out and away from the dashboard. You'll need to remove the glove box before you can remove the right side end cover. Open the box, squeeze it by its sides and pull the door all the way down until you can rotate the lower hooks out of the dashboard. Before you can remove the left end cover, remove the switch for the side mirror with a small, flat screwdriver. To remove either end cover, remove its screws and lower the cover off the dash. The A-pillar trim pieces are at the edges of the dash. Pry them off with the screwdriver.
You will need to remove at least the A-pillar trim pieces and the centre bezel before you can remove the top cover. Once they are removed, unscrew the two retaining screws that were behind the centre bezel with your screwdriver. Disengage the clips at the top cover's rear edge; wrap tape around the edge of a flat screwdriver to prevent damaging the cover and work from the right side to the left. Lift the cover at the disconnected rear edge and slide the cover toward the rear to disengage the front clips.
