Hi I just changed my heater core in my 2000 dodge 2500 diesel. I removed/reinstalled the dash, well here is my problem, My power windows/locks/mirrors side, do not work and the radio lights up but no sound. Did i forget to plug something back in , or maybe a plug came loose? Or maybe a ground its hooked back up. Help, its snowing and this is my plow truck, although my window is down must of the time when I am plowing, I would still like to fix the problem.

 

There is one harness and ground that I had to disconnect when I pulled my dash. Sounds like one is not re-connected. You might look for the harness and try to reconnect without pulling the dash again. If its the ground, I believe you will have pull the dash loose..

 

On each end of the dash, the dash harness disappears into the side of the cab and plugs into the door harness. Give those a check.

 

Check the IOD fuse. Should be #12 in the panel on the side of the dash.
