I have a 2007 ram and the beginning of last year I installed a used older pioneer indash screen. About 3 or 4 weeks after install I got in my truck and it didnt come on, no blown fuse everything checked out. I figured it just died so I took it out and checked it with a battery and worked fine. I put it all back together and it worked for another 3 or 4 weeks and same thing. I then took it out and sold it and went back to stock. About 3 weeks ago I bought a brand new screen and yesterday its happened again. Instead of taking it all out I just took out both radio fuses and reinstalled them and it came on. Im not sure if its the harness adapter, computer or what.. any input?
