My 05 ram 1500 just had a major electrical shutdown 5 days ago! I drove it parked it, shut it off and then it happened! It wouldn't start, no power to anything, the dash won't light up the windows won't work my power seats won't work! I checked the starter and it was fine! So I unplugged both terminals of the battery for 10 minutes and it started up, but as soon as I turn on my fog lights it dies out, nothing at all just the security light on the dash will flash! Any ideas! I had it towed to the dealer. They replaced the starter and the ignition switch and charged me $1000 told me it was fine so I picked it up got on the highway turned on my fogs and it shut down! Idk what to do the dealer tells me they don't know what's wrong and that I'm having a major electrical issue! I just don't know what to do

 

Stop taking it to a dealer for starters. Dealers are not mechanics they are techs and if u dont have a malfunction code they dont know what to do. they will end up replacing parts and if that doesnt fix it they will replace more parts and so on and so on. Take it to a local mechanic shop have them look at it.

 

I agree with the above ^^^. Dealers play guess and check trials at the customers expense(should be illegal)
Take a look under your fuse panel inside the engine compartment. Guys have had odd electrical ssue's due to excessive corrosion underneath where the terminals are.
