cxn613 Posted June 16, 2022 Share Posted June 16, 2022 I have a 2010 cxu613 that the passenger and driver side power mirror, passenger side door lock and passenger window up and down will not work. Sometimes they will work, but more often they won't work. Is there something that is linking these 3 things together. Side note...this unit has manual driver side window. Thanks Quote Link to comment Share on other sites More sharing options...
The Rubber Duck 006 Posted June 25, 2022 Share Posted June 25, 2022 I would check your wiring in the door Sometimes on the CXUs the wiring can get very tiny breaks that are hard to see. Quote Link to comment Share on other sites More sharing options...
CornStalk4409 Posted January 3, 2023 Share Posted January 3, 2023 Hey CXN613, I have a 16 cxu613 doing the exact thing. Have you figured out the issue? I have checked for loose and broken wires, the fuses and fuse panel, and all plugs associated and cannot find anything amiss. Any help by anyone would be appreciated! Heading back into the archives to see if anyone else has resolved this issue. TIA Quote Link to comment Share on other sites More sharing options...
TURBOTALON46825 Posted April 11 Share Posted April 11 I know this is an old thread but i figured i would post a response. I am a technician with 20 years experience on mack/volvo trucks mostly CXN/CXU macks and VNL volvos. The issue is a shared ground between the right mirror/window/door lock circuits. Our fix to this issue is splicing into the window switch ground wire behind the dash switch and running it up to the ground stud at buss bar near fuse panel under cb radio mount. This will provide the circuit with a good ground and should fix your issue. 1 Quote Link to comment Share on other sites More sharing options...
