SOURCE: Is there any greasing nipples

There are no grease fittings on most of today's cars. The squeaking noise may be coming from a dried out suspension bushing.

Hello lindleyjl,

1. You will need to disconnect the wire cove from the upper mirror base. (See image below)
2. Use a flat blade screw driver to disconnect the electrical connector from the mirror. Number 1 in the image.
3. Use a torx driver to loosen the set screw that holds the mirror base to the windshield button.

4. Slide the mirror upward off the the rear view mirror button; number 1 in the image below.

To install, reverse the above outlined procedure.

I hope this helps.

How do you repair a back windshield wiper on a 2004 GMC Envoy? It does not function when turned on.

listen to tell if the motor is turning. some times the fastener comes loose on the arm and can be tightened, but you must first get the motor in the rest position. if the motor is not working, check the appropriate fuse. if ok, you'll need to remove the panel on the inside of the hatch. this should give you access to the motor. unplug, and test for power and ground with key on and engine off. operate the switch while checking with a 12 volt test light. connect test light to ground to check for power, and to power to check for ground. if ok try tapping on motor. sometimes this will make it work, but only on a temporary basis. motor replacement will be obvios when you see how it' smounted under the panel.
