What does the 30v fuse under hood control? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Hi my shop just wired my leds to stay on all the time and used a relay on the 30v fuse to do this. Does it control the windows? Cause now when i roll up my windows parked my rpms drop slittly??

Thanks for any help

My rpm always drops when I use my windows whilst parked. Along with turning on any electronic function for that matter (rear defroster, seat warmers, etc.) Not too sure about that fuse your talking about but thought I could provide some sort of insight on the windows and dipping rpm

There is NO fuse called 30V, could you be more specific I can get the wiring diagram based on the fuses.
