Hey y'all I'm having problems with my Dodge Ram 1500, my power windows aren't working, my power locks work when they want to, my speedometer gauge doesn't work, my speakers, reverse lights, blower fan, and my information gauge don't work right (up top in the headliner). Anyone know what would cause all this at the same time? any help would be greatly appreciated I've been trying to figure this out for over a year now.

 

You have a selection of problems. There is more than one thing going on there. You can grab the service manual for your truck from here. Wiring diagrams are in section 8W. Pick a problem, solve that one, move on to the next.

 

They all quit at the same time... Do you really think it's all separate things?

 

I do think there is more than one problem. Think I would go after the speedo first. (that is something you really need working properly.....) It's entirely possible that if you solve one issue, it will take care of a few more as well.

 

Does it have problems shifting when the speedo quits? If it does NOT it could be in the dash or a connection issue. Have you tried the dash test?
