Repair 7

Ensure the engine is off and the keys are not in the ignition. Apply the parking brake.

Wedge the small screwdriver on the upper point of the triangular sail of the mirror. Gently pry the plastic sail outward and then unsnap it from the mirror.

Open the door wide to locate the bottom retaining screw of the mirror. It is hidden by the door frame (at the bottom of the mirror housing) when the door is closed. Remove the screw with the T27 Torx-head screwdriver. Close the door.

Remove the other two screws (visible from the removal of the trim sail). Support the mirror with one hand when removing the last screw so it does not fall against the door or fender and scratch the paint.

Remove the manual mirror or for the powered mirror, gently pull the wire harness up through the access hole until the plug connection can be accessed. Press the locking clip on the harness to disconnect the mirrors wire from the wire harness plug.

Reverse the procedure to reinstall the replacement mirror, powered or manual respectively. Plug the powered mirror harness in first and feed it back through the access hole. Replace the upper retaining screws of the mirror first and open the door again to replace the bottom screw. Snap the trim sail back on to complete the job.

Open the front door. Find the screws that hold the door panel and mirror trim in place. Remove the screws with a screwdriver and remove both the door panel and the mirror trim.

Find the screws that hold the existing side mirrors in place. Remove the screws with a screwdriver and set them aside. Disconnect the wires in the old mirrors. The wires should be connected in a cable that is simple to slide away from the wiring in the side mirror. Slip the old mirror out of place. Repeat with the other side mirror.

Thread the wiring of the new heated side mirror through the hole in the door. Screw the mirror into place with the screws that you set aside. Connect the wires in the heated mirror to the wires in the door. The cables should connect easily. Replace the door panel and window trim and screw them into place with a screwdriver. Repeat with the other side mirror and door.

Open the drivers side door wide, power down the window and then remove the keys from the ignition. This will prevent accidental power supply from being demanded while removing the power mirror.

Remove the two screws located at the bottom of the door panel, using the Phillips screwdriver.

Pull the front end of the door handle trim by hand to release the six retaining clips located on the underside of the trim.

Pry the window control module away from the front of the arm rest, using the trim pry tool. Remove the wire harness connections from the underside of the window control module, then set the module aside.

Remove the door panel retaining screw now revealed by the window control module removal, using the screwdriver.

Disengage the door panel clips by using the trim pry tool to pry the panel away from the door frame. Start at the bottom and work up each side. Remove the door panel by lifting it slightly upward and then away from the door frame.

Remove the foam insulation from the opposite side of the door frame to the drivers side mirror.

Disconnect the wire harness plug, now revealed from the foam insulation removal, from the power mirror.

Remove the three retaining nuts attached to the drivers side mirror studs, using the ratchet, extension and socket. Brace the old mirror when removing the last nut, so that the mirror does not fall and scratch the exterior paint on the door.

Install the replacement mirror and reconnect the door panel, window control module and door handle trim piece by reversing the removal procedure.

Roll the window down all the way on the door with the mirror that needs replacing. If the Sonoma has power windows, turn the ignition to the "Off" position and remove the key from the ignition once the window is down.

Align the window crank removal tool (manual windows only) behind the length of the window crank. Pry the tool in between the crank and the door panel to unseat the retaining clip. The clip snaps over the internal section of the crank and will pop off with a slight spring force. Be careful not to let it fly off and get lost. Pull the window crank off its shaft once the spring is off.

Remove the two screws in the door pull cup with the Phillips screwdriver.

Pry the outside edge of the door panel (between the panel and the door frame) away from the frame with the trim panel pry tool. Work the pry tool to the bottom of the door panel and then to the other side to unseat all the plastic internal fasteners.

Push the door panel upward slightly to unseat the lip of the panel secured to the ridge of the door/window frame.

Disconnect the wire harness located on the inside of the door panel and then remove the door panel.

Disconnect the wire harness for the side view mirror (power mirrors only).

Remove the three retaining nuts attached the the side mirror studs with a ratchet and socket. Brace the mirror with one hand when removing the last nut, so the mirror does not fall and scratch the paint on the door.

Feed the wire harness (power mirrors only) through the access hole in the door frame to remove the mirror and harness from the Sonoma. For manual mirrors, simply remove the mirror.

Install the replacement mirror (manual or power) by reversing the removal procedure and then reinstall the door panel by reversing the removal procedure.

Open the hood to the vehicle.

Put on the safety goggles.

Place a suitable sized box-end wrench or a ratchet and socket on the hex-head of the (black-wired) negative side post battery terminal (removing the negative terminal post first will minimize the occurrence of sparks flying from the battery terminal, which could result in igniting flammable hydrogen gases emitting from the battery vents). Many GMs use an 8mm or 5/16-inch wrench (although aftermarket or converted side posts terminals may take a much larger wrench or socket). Also some side post batteries, but not all, restrict using a ratchet and socket due to limited room between the terminal post and other engine components.

Turn the wrench (or ratchet and socket) counterclockwise. Keep in mind that if the battery terminals are facing the engine compartment, the terminal bolt will require being loosened to the right (clockwise) in order to remove.

Isolate the battery terminal bolt from the battery so it does not come back into contact with the battery post while removing the positive (red-wired) battery terminal side post bolt in the same fashion. Some GM vehicles come equipped with a plastic cover for the positive battery terminal post to help prevent corrosion. If equipped, unsnap the cover by hand first.

Turn one side of the mirror into the housing like you would when adjusting it. If changing the drivers side mirror, push in on the right side of the mirror. If adjusting the passenger side mirror on the Tundra, push in on the left side of the mirror. When you push one side of the mirror into the housing, it causes the other side of the mirror to extend out of the housing. This allows access to the back of the mirror. Make the adjustment with the mirror motor via the electronic adjuster on the inner door panel or do it by pushing on the glass with your hand.

Squeeze your fingers behind the Tundras side view mirror and pull outward on it to separate the ball and socket connector. It takes a small amount of pressure to break the two apart. However, you will not damage the mirror motor.

Place the new mirror into the housing. The mirror is a tight fit inside the housing. Because of the tight fit, the ball and socket connector automatically lines up.

Push on the face of the Tundras mirror with the ball of your fist until the ball and socket pop together. You hear a small pop as the two press together. This lets you know the mirror is securely attached to the motor.
