Hi, I have a 1993 GMC Safari Van, w/power doors/windows. The problem:  On the drivers side door, the window goes up and goes down when it feels like it! Usually does both in incriments at a time. Very frustrating!!! Please answer the following for me:
**There, inside the door panel, there is a 1x2" connector box with about 4-5 prongs on it where the wires plug into it. Could this be the problem? The vehicle has 130,00 miles on it, and it is the original part. If it is the problem, at our local Auto Zone, they carry this type of part, but I hate to buy it if this is not the problem. Most stores won't let you return electrical parts back for a refund!
**This box with the prongs on it.......if it is bad, is it a type of deal that it will just never work, or it will work when it wants to if it is GOING BAD?
**Like is said, I'll try to bring the window down, and it will just stop. Wait a few minutes, and it will move a bit more, etc., etc. Same thing when it comes time to close the window!!

Please help me solve this issue with any suggestions that you may have for me?

Thanks !!!!

Answer -
there are usually two prob. with power windows. Either the switch is bad which means its not reversing polarity..Or a bad motor try tapping in the motor while pushing the switch. If it works while tapping its a worn out motor. if it doesnt change I would say its a bad switch.  
 Hope this helps.

Hi Brian, Sorry to bother you again but could you please tell me where i would find the Pwr. Window motor for this door to tap it to see if this might be the problem? Finally, does each door have its own seperate motor per window?

Thanks!!

Answer
The power window motor is located someware inside the door I dont have an exact location Because every model is different. With the door panel off you will be be able to see it. Every elecrtic window has one. that box box you are talking is the auto down which is when you push your down button it automaticaly goes all the way down.
