Im suspecting pcm. First issue was front turn signals staying on after truck was no longer running. Then tail lights went. Wont work at all. Brakes turns or anything. Then speedo went. Also no wipers. All other gauges work other than fuel gauge wouldnt read properly 10,000 miles ago. All other issues went within 3 days. Iv checked all connections, plugs and grounds front to back and batteries are good. Iv had this truck for several years witj no issues whatsoever other than basic maintenance. Also does anyone have any luck with the ecm repair. If so any suggestions on that?

 

Bullett, you may have a failing power distribution center...PDC. I had some weird things going on with my lights and that was the problem. I had a dealer trouble shoot it but didn't buy from them. I got mine on line for half of the dealer price...HTH

My buddy's 03 had weird stuff with lights going on and it was the PDC. They have small little slots in the box making the box open to the outside air and it lets moisture in creating corrosion over time. Why this box isn't sealed is an interesting question.

The replacement comes in two parts and that kind of seals up the bottom. I figure that got my monies worth out of the oem as I had @415k on it...LOL
