    I was installing a new headunit in my truck, and when everything was connected I noticed cluster lights worked (gauges) but the A/C illumination and shifter ought do not. They run on a similar circuit why do these not work and how to fix.

    Solved the problem. Turns out it was an AM1 (7.5A) or the A/C (7.5A) fuse as both of those were blown. This saved me having to possibly order a new gauge cluster based on some information I seen on a 4runner form.

    Does anyone know what the AM1 fuse is used for beside the illumination of the A/C and push buttons.

    What caused the fuses to blow?

    Cheat sheet attached below. AM1 is part of the shift lock system. Did you disconnect the negative battery terminal before starting your project? If not, that may have caused the fuses to blow.

    No, I've usually been very very careful, but for future projects I will. I was worried for a few days about the gauge cluster having to be replace. Definitely printing off a copy of this cheat to have on hand.
