Hello all, I am having major electrical problems. Every time I start my truck I have different issues ex. Engine hot/ac turned off, power locks won't work, parking assist off, rough idle. These conditions come and go sometimes they all occur at once or one at a time and some days no issues at all. I have replaced the battery terminals checked the various ground connections and fuses but it's still anybody's guess which condition will show up with the turn of the key. Any help in this matter is GREATLY appreciated.

Seems like a loose connection somewhere. How "clean" are the connections at the fuse block, ignition tumbler, battery?

 

Any codes come up?
