Ford Repair: 1979 Bronco, wd 40, window regulator

Question
Hi, question on tailgate window.  My window is very slow and sticking on powering up and down.  This is related to the tailgate motor or window regulator ?  Is this common ?

thanks

Answer
Hello Derek, Yes the issue is more that likely related to the power motor and or regulator. The regulators will rust up and bind and the motors would get week. you may have some luck and get the cover off and spray like wd-40 and roll the window up/down. Have difently seen this before. Hope this helps Thanks Tony
