No horn and no right hand turn signal bulb good,icannot find fuse to the horn ifound signal fuse it is good

Horn also uses a relay . What year , make , model vehicle. The odds of the fuse being the falt are high , Fuse's do blow , but not for no reason . Short's to ground cause fuse's to blow . Which means electrical wiring problems or short's in electrical componets . Do you know what a relay is an how it works ?

Why does my turn signal/ hazard light fuse keep blowing out

you have a short in one of the light sockets or a worn wire from the wiring harness. could be the flasher assembly. are the turn signals different bulbs from the brake lights? Does using the brakes blow the fuse? (Rear lights or brake light switch on brake pedal). left or right turn signal blowing the fuse will tell which side has the short. 4 ways only, replace the relay.

1987 F-350 1 Ton Dump; after breaking a RR turn/brake light housing by backing into a firewood pile while delivering firewood, I have lost front & rear brake & turn signals. My ohm meter indicates...

The fuse #5 next to the flasher should be for the turn signals. Fuse number 1 is for the stop and hazard circuit. Everything goes thru the turn signal switch so the short could be in there. You would need to unplug the turn signal switch to check the circuits with an ohm meter.
The brake and signal circuits are separate until they get to the turn signal switch.

My tail lights/reverse lights are not working - either side. checked the fuses, they seem fine. the brake light above the tire does work? any suggestions - going to see my Dad Sunday (old mechanic),...

reverse is a whole different circuit. via the transmission reverse switch..
my guess is you have burned out lamps.
im looking at now. (so can you)
and i will pick the Reverse page, its boy scout simple
battery, fuse 39, wires a switch and 2 lamps.

i bet fuse 39 is blow,
replace, it. some that look good, are in fact not (micro cracks)
or use an ohm meter (dmm set to ohm low)
0 ohms good
infinity bad.

there is a fuse box in engine bay and cab.

How can I figure out why fuse 15A keeps blowing? My dashboard lights don't work nor do the back lights. My breaks and signals work but at night when I turn the car on the regular lights in the back...

There is a shorted wire somewhere in that circuit. Check to see if any wires are pinched under a bracket or brace where he was working. I have seen it where it was a light bulb the was bad. Need someone familiar with a volt/ohm meter to help trace problem. Good Luck. You did not state where he had been working.

Hi, I have a 2002 Jeep Wrangler Sport. The turn signals just sopped working. Have replaced the flasher and the turn signal switch and still no blinkers. Checked fuses they are fine also. What else...

I assume you must have also checked the rear turn signal bulbs.
You may have to start using a volt meter. Check for 12 v at the bulbs also check the bulb ground...that's a common cause of light problems.

I was wiring a trailer pigtail to an 06 wrangler and blew the turn signal bulbs but the fuses are good. I have running and reverse lights but no brake lights or turn signals

If the bulbs and the fuses are good, check the brake light switch. You might of shorted out the switch when working on the pig tail. Always use a test light or volt meter when installing pig tails. This way you can check for power and ground before hooking a wire up to help prevent shorts. But by what you have said it does sound as if the brake light switch is now bad.

1984 ford ranger keeps blowing the running light fuses. when i let it sit at idle it won't blow the fuses but as soon as i start driving with in 5 mins or so it blows.... any ideas?

short in the wires will need a wiring diagram and ohm/volt meter to locate the problem, test lights work well to.
you will need replace the fuse with a light bulb so that the power will not go away. and you will have to search for power going straight to a ground source.
usually a raw wire from rubbing somewhere. can do a quick visual inspection first for the obvious, and then use the meter at certain points till you find a volt drop.
