Question about 2008 Mercury Grand Marquis
#18 fuse that protects interior lighting blows after replacement.
Pick up an automatic circuit breaker at a parts store making sue it is the same ampereage. Put it in place of the blown fuse and give it a few seconds. It will trip and reset itself, giving you an opportunity to check which light is shorting out. Try a fuse 5 amps higher and see if it blows. If not, it just might be a load issue and not necessarily a shorted circuit. Perhaps the fuse was replaced before with one underrated. Do not exceed 5 amps over what you pull out. Good luck and keep a n eye on everything until the breaker breaks the first time.
