elctrical gremlin? 07sr5

ok hopfully someone can help me. i have an 07sr5 2wd 4.0., my tanyone have any insigadio randomly shuts off but when it does my A/C doesnt work and all the lights around my radio stop to. if i press down on the fuse box it will work again or if i shut the truck off for awhile. i can see anything wrong with my fuse box or fuses. does anyone have insight.

 

electrical gremlins are always a PITA and I'm no expert by any means.

Checked the wiring diagrams in my Chiltons manual. There are apparently two fuses associated with the radio receiver assy. One in driver side junction box and one in the engine room relay block. I'd start by checking both of those for proper seating, contact dis coloration, or even dirt or grime in the slot contacts.

 

And coming off the radio receiver assy Brown wire goes to ground. Not always, but a few times I've had to deal with this kind of intermittent electrical prob, a loose ground can do really weird stuff.

 

thanks guys ill check that stuff tonight and get back with yall.
