The fuse for the interior lights of my '99 Suburban keeps blowing out. Any thoughts???

Best first 'guess' would be a defective headlight/parkinglight switch. Wiggle/bump test. The smell test is helpful too. Otherwise you will have to test for a short circuit. DO NOT PUT A BIGGER AMPERAGE FUSE.

Not much I can Add to that... Definitely a big no-no to put in a bigger fuse...
