I should add the battery and alternator were tested and checked out fine

Problem was intermittent- door locks engaging, power windows work/don't work, ac sometimes wouldn't blow cold etc. Now, no power locks/windows at all. Radio won't power on. All dash gauges do not work. No cold ac. Truck starts and runs fine. I've checked all the fuses visually and with a multimeter. And all are fine. Checked most grounds. 1 was iffy (passenger side engine block so I ran a new one by splicing. Didn't help. The other block to firewall looks possibly suspect but I can't get to the bolt to remove. Other grounds look kinda old but not worn. I can not get the battery ground bolt off as it's rusted on so maybe that's an issue Any other suggestions.
