Power window demon

[5thGenvtec]

Hi Everyone, I am new here so please help me if you can. I have a 99 si (ex usa) and my problem is with the passenger side window. I have no response from the driver side control and the passenger side control only works to take the window down. I tried a new assembly and the same thing happened. Right now I am really lost here so please any help would be greatly appreciated.

What new assembly ??

Have you tried putting voltage direct to the disconnected leads of the motor to see if it will move then ??

Okay, here is where I am. I applied power directly to disconnected leads and nothing happened, so I applied ground on one side and power on one and I got up and down movement dependind on which way the power/ground was applied. So might this be a problem with the harness itself? and if so, how hard is this to change if I can put my hands on one?

Here are the schematics for the system. It may help to troubleshoot the problem. You should try to locate the free factory 96-00 Civic service manual on the web. It will have the procedure for checking the switches and wiring.
