My rear window defogger did not defog this morning. I tried to check the 50 amp fuse but it is under a long narrow cover that I found very hard and cumbersome to remove. Does someone have a suggestion as to how to accomplish this?

I did see in another post regarding a 2002 SC430 model where the responder said to 1) check that the wires on the glass are not broken (mine are not broken) and then check if the outside rear view mirrors get warm to see if the switch is OK (my outside mirrors do get warm).

Where I am confused is the responder then said to use a meter to check the fuse for continuity and if the fuse is good then he/she said it narrows it down to the "relay for the defogger relay and wiring harnesses". But what I don't understand is that if the outside mirrors get hot then doesn't this automatically mean the fuse is OK?

Any help would be appreciated.

yes the service manual says the rear window defogger is linked with the mirror defogger so fuse should be ok. Like u said that leaves the relay and wiring harness. maybe this is useful.
