Hi all, so recently replaced my passenger side window regulator and both passenger and driver control switches and the window still wont roll down, but upon further investigation i noticed that that only the passenger switch to roll the window up will give the motor power, any help would be appreciated thanks!

 

Open up the drivers side door harness and check for a broken wire. Re connect, and test. The wires are dry and old and get tired from being opened and closed inside a door jam.
