Changing 100 amp fuse - '97 ES300
In replacing the 100 amp fuse I have to release the sub-assembly fuse box holding the 100 amp fuse from the main fuse box in order to access the connection bolts. However I've been unable to release the latches holding the sub-assembly box to the main box. I've used a small flat-head screwdriver in every way I know but no success. Any suggestions?
