Hey everyone!

First post could not find any old post that would help.
K heres the deal I have a 1989 Toyota 4wd v6 ex cab the 10A fuse blows out
Heres what I know
-blows right when I turn the ignition
-no power to blower ac/heater
-no temp of fuel guage working
-no reverse lights

So far I have tried removing the blower relay and fuses but still blows fuse
the wiring looks pretty good from last owner no hack jobs I yanked out the whole dash to get a better look in there only thing i noticed is the blower speed switch had been replaced and one tab on the plug has some evidence of burning. Any help or direction would be great thanks.

 

try a larger fuse

 

WRONG ANSWER, the fuse is blowing for a reason, and adding a bigger fuse will only make things worse or worse case start an electrical fire.
