Front Window Regulator Assembly Removal and Installation

Check motor movement as follows.
1) Connect battery positive terminal "2" and connect battery negative terminal "1" for 3 seconds.

Do not apply reversed polarity to terminal "1" and terminal "2" as doing so causes motor burnout.
2) Connect terminal "7" (DOWN) or terminal "10" (UP) to battery negative terminal and disconnect it immediately.
3) Power window motor will operate if terminal "7" (DOWN) or terminal "10" (UP) is connected to battery negative terminal again within 2.5 seconds from above procedure.

If operation is not smooth, check glass run, door outer weather-strip, door inner weather-strip and grease in link. If those parts are in good condition, replace window regulator assembly.
