Missing Fuses UnderHood....
Ok, I've got a 3vze 90 auto 4runner. Today I noticed my CMH fuse/relay (?) was missing. It's in the main, rectangular fuse box, closest to the front of the vehicle. The order is HEAD, EFI, CMH. What does the CMH do and is it a relay or a fuse?
Thanks,
Steve

Hey,
My '90 3vze auto 4runner is missing the same fuse (or whatever that is). Maybe some 4Runners don't have it? As to what it is for, I have no idea.
Maybe ABS? My 4Runner doesn't have ABS (at least not that I know of), but I think it may have been an option.
Well, have fun.

CMH is the Cold Mixture Heater relay... some gizmo attached to the carb or throttle body from memory.
I looked it up a while back (as I'm 'missing' it too) but one can never find such info when it's needed :pat:
I think vehicles that were sold in cold climates also had a fuel heater too
