I have a 2013 compass that about 1 year ago had problem with driver side window stuck down. Mechanic did some troubleshooting but could not find a issue. After her put things back together the window worked. Few months later same problem with same window and left rear window this time. This time troubleshooting found no issues again but after normaling everything up still neither window worked.A month ago all windows failed to work. Mechanic tested controller, fuses etc. And all are functioning normal. He did notice when he moved the entire harness leading to the controller one window went up but would not go down. Any suggestions on next steps in troubleshooting would be appreciated.
