i have a 1995 honda accord 2dr ex,the passenger side window motor stopped workin completly,not making any noise at all.i checked and have power all the way up to the motor itself. is the motor grounded to the door through the bolts it mounts with?or does it have its own ground?any ideas or previous experience would be appreciated.the car has been sitting for a year and a half in a garage.but the window worked a month ago when i washed it.are the units sealed could it have gotten water damaged?

thanks in advance for any help.

If you have power to the motor connector then it's easy to find the ground. If you have 2 lines plugged into your motor then the ground is most likely brought in through the harness, just check this with a multimeter to see if you get a voltage reading with the window button pushed. If there's only a single line going into the motor then it's a tell tale sign that the motor uses a bolt as a ground source, again check this out with a multimeter.

the first thing you should do is check that the motor works. If you can get to the motor contacts real easy then this will be a snap. Use some lengths of wire and run a positive and negative source straight from the battery to the window motor, make sure the motor is getting direct juice from the battery. If this doesn't work then give the motor a light tap with a screwdriver while connecting power. The motor may have developed a dead spot from sitting so long and sometimes a light tap will generate enough vibration to get it going a little past that dead spot. If the motor doesn't work then it may be toast. If it does work then you need to find the break in the circuit.

Next thing you should do is clean the contacts of the connectors to make sure corrosion has not blocked the electrical connection.

If your ground is going through a bolt then you could take out the motor and sand all the mating surfaces a little bit to make sure you got a good ground connection. You only need to sand about 1/8 inch all around the bolt hole to make for a good connection and make sure you sand all the way down to the metal, don't just scuff the paint. When you do this you should go the parts store and ask them for some dialectric grease that will prevent rusting as well. Put this grease on any bare metal you exposed and that should prevent future problems from the exposed metal.

If you do all this and can't get the motor to work then it's toast, pull the homemade battery lines you made, skip the dialectric grease and throw some primer on the bare metal you sanded cause your motor is toast. Buy a new one.

Really? Then how would you have up/down control with only one wire?
