Wife put e85 gas in the car and now the fab for air and heat plus cigarette plug no power plus high beam head light not working all other lights work fine and it drives and cranks with no problem. Not sure what fuse or relay controls any of these but I have checked all fuses under dash and the hood not sure about relays how to check.
Thank you

There is a fuse #49 and fuse #30 on the left side of the dash fuse panel that needs to be checked for power. here is a guide to help you and the fuse location in the images below:

These fuses run the blower motor and the cigarette lighter power socket if neither have power and the fuses is okay, I would replace the terminal 75 power relay (relay #1 inside the 12-relay carrier). I don't think the e85 would cause this issue. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.

Okay, I am not sure which ones I should replace. Is it from top number 1 left to right or bottom left to right as a am looking at it. Thank you so much for the help.

The fuses all check out good. Also looks like a main power relay zip tied in that is on bottom right as looking at it.
