Re: headlights don't work, fuses keep blowing out
Check the wiring too the tailgate it very common for it to break up and tuch other wires, also check trailer socket wiring,if it has one it will be a black wire and a brown one for the side lights.Good luck Davelee

fuses blow because of dead shorts or excess current draw
to blow a 15 amp fuse indicates a dead short
by disconnecting the rear lights , the problem is in something else you have replaced
could be a problem in the head light wiring
These are all different circuits. The brake lights are on a 10amp fuse - the headlights are on a 50amp fuse - and the parking and dash lights are on a 20amp fuse. Do you have power going into the headlight switch and the brake light switch ?
12V power passes through 15A fuse 33 (the one that keeps blowing?) in the battery junction box and on to the main light switch. When the main light switch is set to PARK, 12 volts is routed via the BRN lead to the park filaments of the dual park/turn lamps. These lights remain on when the headlight switch is turned to HEAD.
The main light switch gets its 12V input from 7.5A fuse 11 in the central junction box and the same 15A fuse (33) identified above. When the main light switch is set to PARK, 12 volts is routed via the BRN lead to the instrument panel dimming module and module output is applied to the panel illuminating lamps.These lights remain on when the headlight switch is turned to HEAD.
The input to fuse 33 is hot all the time so should read 12V. If you read 12V at the TAN/WHT connection with the fuse out, something is definitely not right. I'm sure you have noted that the fuse is common to the non-functioning circuits you mentioned.
These bulbs last a long time and if they'er all out you might find the running lights ( taillights arn't working too. ( blown fuse) the panel lights are on a separte fuse but they run off of the tailight fuse. the tailights are really all the lights that come on with the headlight switch except the headlights themselfs. Then that circuit entergizes the panel lights thea light the dash gauges the door panels switches the any console lights the car can have. the dome circuit is another fuse that lights the floor and dome ( if their is one) and any landou lights (piller) sometimes this fuse is removed or blow and the dash lights don't work, Or sometimes just a few. The cluster can be removed but not all of the bulbs can be bought at the parts store as the lights are to be replaced by rebuilding the cluster and can't be serviced. Agin some of the door switches are made this way also and you have to replace the switch to get a good light in them.
The positive wire in the headlight circuit is shorted to ground someplace, you have to check the wire by following it from where it connects to the headlight back to the switch and then to the fuse block
