Hello my name is ***** ***** i will do my best to help you , i strive for EXCELLENT service and nothing less. Usually whenever the one touch keeps moving the window back down it is because the window motors senses a restriction or slowing of speed so it reverses the window for safety. So you can do two things.
1- disconnect the battery for a minute. Then reconnect. Then pull the window switch up WITHOUT clicking the window switch to the auto up feature and KEEP holding it up when the window closes and you will hear the motor click off after 2-3 seconds indicating the one touch was learned. You only have to do it in the up position. There is no learn in the down position.
2- before you disconnect the battery , clean the felt inside where the sides of the window slide. Use a silicone spray that is a dry lube type made by 3M products. Usually just cleaning and lubricating the side of the window slides will free the window up so it will stop reversing.
