How Do I Replace the Side Mirror on My 1994 GMC Sonoma

Like many GM vehicles, the 1994 GMC Sonoma requires the removal of the interior door panel to replace the side view mirror. This task might intimidate many people but its not overly complicated. As a matter of fact, the first time a would-be home mechanic tries this and realizes how uncomplicated it is, he may desire to step up to bigger challenges. Replacing the side view mirrors on the Sonoma is less complicated than learning how to use them to back the truck up.

Instructions

1

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.

2

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.

3

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

4

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.

5

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

6

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

7

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

8

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.

9

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.

10

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