Check the intake throttle valve for a loose plate or worn shaft bore. Do not attempt to tighten the screws. If it's loose, try and hit a mailbox with it on your way to the dealer for a new one. Modify the new one. If your current one is good, modify it. The numbers here are metric. You're...

Check everything, despite how they are labeled. One fuse may power 10 different circuits.

It's 1:48 AM. PM me in the morning.

If there is no power at either switch, then I'd start checking fuses, connectors, etc. On this particular truck, there was no cover for the fuse box on the left fender. Road salt got in it. After a lot of scratching at the contacts and replacing fuses that looked good but weren't, I STILL...
