Question about 2005 Chrysler 300
The passenger mirror did not work when my wife first test drove the car. When I tried it it worked fine. We have had the car for 6 mos. and it stopped working. The switch still operates the driver's side mirror. Probably a short but where should I begin?
Unlikely a 'short,' those cause blown fuses and smoking wires.
The switch may be flaky and not contacting as it should when operated and this failure mode is called an 'open.'
Not knowing exactly how the switch is constructed nor mounted, I can't tell you how how to access it. Many switches have expansion struts on their sides that may lock or notafter being pressed in, but using care, you might try with two butter knives you don't give a hoot about, one to slip the tip under an exposed bezel (if it has one) and the other to place under the first so when you pry by rocking the top knife back and forth, the area under and around the switch doesn't get damaged from the prying.
If you can remove the switch assembly and pull it slightly out of its hole, remove the plug or plugs and reconnect them several times to 'wipe' the surface of the connector(s). Sometimes the crappy plating on connectors just stops conducting from oxidation. If the switch is constructed so that some 'tuner (or contact) cleaner' (from an electronics store) can be forced into the innards of the switch, you may be able to restore function.
I don't think it is a fuse problem as there is probably one fuse which services multple devices but it could be a failed motor.

It is not a short, but an open circuit, the first thing to do is pull the power mirror switch and test the contacts of the mirror that works with a 12 volt test light, then switch to the in-op mirror, it should mirror the test light results of the good mirror, if it does then the mirror motor is defective, if you get no power out of the switch then the switch is bad, in the field I see far more bad switches than bad mirror motors, the switch is cheap, the mirror very expensive, and only replaceable not repairable.
