In fuse block. Ok, that's a smart a** answer. Not sure where the fuse block is located on your vehicle, but usually under dash left of steering column, or under hood on inner fender, or in glove box, or? Using a flashlite you can often see which fuse is blown by eyeball. If not, remove one at a time and examine. Other reason for horn to fail is horn relay bad. If only one horn fails, bad horn. Both fail = relay or fuse or broken wire.

Voltage from the brake light switch deactivates the cruise control . Have an assistant press on the brake pedal while you check that the brake lights are working properly. Brake lights that dont come on or dont shut off need to be fixed and go from there. Sorry if this doesnt answer you question but I thought i would give it a try.

Be sure to have tires rotated every 5000-6000-miles. Walmart is good for that.
Outside wear is normal for fronts from the turns at higher speeds.

Info is a little fuzzy, but here are some solid clues. The 6th and 7th digits of the VIN should be 71 or 72 if it is a police or taxi model. It should have a certified 140 mph speedometer and full set of gauges like the Crown Vic. Very few Grand Marquis models were built with the 71 or 72 package because Grand Marquis was not sold to fleets like Crown Vics were. I would be surprised if you found a hand full of any year after 1995 in the USA still on the road. The 2003-2004 Marauder would be the exception but they are rare too.

Most of the time, one defect triggers another, and so on, and if the primary problem is fixed, the other defects may clear when given some time. The easiest of your Codes to fix is the P0401. This is an EGR airflow Code problem in the throat of the airhorn. The passageway which feeds the EGR is dirty. You need to clean the port between the intake and EGR. Code 1131 is lean reading from O2. Can be restricted fuel injector or low pressure, or too much airflow to cylinders from a leak. Code 1151 is a Vacuum leak. Can be detected with engine running by spraying water from a spray bottle to seams and lines. Codes 1233, 1234. Bad connections on wire ends, (Known defect of Factory crimps) At fuelpump, inertia sensor, or fuelpump module. You need fresh fuel. Fuel injector cleaner could help. The water spray can detect leaky gaskets that are dried up. You could easily have corrosion on connections, especially under the car.

Don't know what "sh lights " are but it's time to start checking fuses and conectors for the lights and I've had radio's just take a dump out of the blue! Shot!

I would recommend having a shop do the job. If you want to try it buy a good repair book. The heater box on the firewall comes off and the dash comes out of the inside of the cabin. Its a major job.
