If it's the 'box, I've found a great way to clean them is to soak them in vinegar overnight. Gets rid of the corrosion, then spray them with some grease that's safe for electronics.

Check the fuse block. It's probably melted. I've had this happen 2-3 times. If / when you get a new fuse block, clean the fuse terminals real good. A little resistance + high current from the headlight load = heat.

Check fuse.

Then check headlight relay..box thing in engine bay. Then check that no bodgey wires are hanging, left over from a backyard driving lights install. If a live 12V shorts on on the headlight circuit, then you'll blow the fuse fot the headlights. Also the actual lights are easy to replace. Remove the grill, and there's 3 screws for the headlight retaining ring. Pull the plug off the back. Easy.

Check ya fuses and wiring, both headlights wouldn't blow at the same time....surely
