Take the door panel off! if you do not have time to "DIAGNOSE" leave the panel off till you do. You can not fix anything if you do not know what's broke. Not only do you need to hit the bullseye on the dart board, but you need to at least aim for the correct dart board. The more you do the more you learn, you will as a result fix more things yourself, saving labor cost, but can help others also. once you get the panel off ( have a 12 oz. SMALL hammer at the ready). there are two wire that feed power to the window motor. The automatic up and down is internal in the window module. once you find these you can do your first test ( you will need a quality volt/ohm meter. Quality does not mean expensive (expensive ones can be more durable) Harbor freight has a good selection- get one of their better ones and if they have lead extensions get ones long enough to reach the battery ( just like an extension core you use when the living room light is move to the other side of the room. Lets say the wire are blue and black, when you push the button in the window down direction ( one wire will be hot the other the ground - whether the window moves or not) When you cycle the window by putting in the up direction they will be reversed. If this happens take you small hammer and has you hold the button - or someone does- hit the fat part of the motor. If window works you know what is wrong ( brushes worn in motor) Get a new motor or some only come attached to the regulator assembly. If not you have to find out what the electricity is not getting to the motor. The same two wire will be at the switch, test there the same way if it is ok there a wire is broken somewhere (usually where the go thru the door hinges). Good luck electricity is easy.
lesson 2 is how a river is like electricity! Volume of water = amps, Speed of waters movement= volts, number of rocks in the stream= resistance(ohms)
