You have a bad injector. Unplug all your injectors then replace fuse if the fuse is still good after you turn on the ign (don't try and start the car) Then shut the ign off and plug in one injector at a time checking your fuse every time you plug one and turn ign on. you will find it if there is a bad one. Remember turn key off before you unplug or plug one in.

Check the cylinders Commpression. over 115 psi is good, 120 psi is normal.

I'd look at the door switches (for dome light) first, then check that light itself has not shorted against roof. Does the fuse blow when the bulb has been removed? Some of this stuff has been routed through "modules", depending upon options and mfg date.( Delay controls and others.) I have seen no less than three "diagrams"... none of which are specific enough to aid in repair. If you physically can't trace problem, you will need the exact wiring diagram specific to manufacture date of your vehicle (can be 6mos different than just year.)

look for Main A/C relay, look for fuses, or go to a/c shop and have gas check out, perhaps leaks, perhaps evaporator, perhaps condenser, but start for relay box on front passengers side, or fuses on same side

I just had the same with mine, pull the rubber boot back on the drivers side front door and look for a severed wire, mine was black...simply spliced the wires back together and problem solved!

go to the horn under your hood, check it for any thing wrong, then follow the power wire and follow it back to your steering wheal. this is where your problem is you just have to find out where the short is. and fix it.
