I have a 1999 4wd that developed gremlins. After reading on here it sounds like the GEM module. All well & good. I get the panels off, unbolt everything, but can't get the fuse box off to reach the GEM. YouTube shows a tab on the face to be depressed, but there is no tab to press on mine. Literally nothing there but more plastic. How the heck do I get this thing off to reach the GEM?
