Trailer wiring i hooked up a trailer which i ended up finding out the trailer had a short and shorted out the trucks trailer wiring. i found a fuse that was blown and replaced it but it still wont work. any suggestions.

You have blown a brake light fuse is my guess due to shorted trailer wiring, The shifter is locked in park unless the brakes are applied and they work. Check the brake lights.

Check under the hood fuse box for trailer and vehicle fuses.Use a test light and check all fuses in place.Turn ignition and light switch on when checking fuses.

probably a blown fuse. in trucks with trailer packages the trailer lights usually have their own fuses. either in the under hood fuse block or possibly under the dash. if it's blown replace it, if it blows again check for a short in the trailer wiring.

There is a short circuit to ground. I am constantly preaching that it does absolutely no good to replace a blown fuse until the cause of the blown fuse is found. Fuses do not blow for no reason. If you have a blown fuse it means that you have a circuit overload that could potentially burn you truck to the ground. Simply replacing the fuse will only cause another fuse to give up its life to save your truck from roasting. On pickup trucks with trailer hitches, the first place I look for a problem with tail lights is in the trailer wiring harness. They are usually not installed properly. I have seen several of the plug-in type trailer harnesses (the kind that simply plugs in at the connector between the body harness and the bed harness) short internally. You can usually fix the tail lights by simply disconnecting the trailer harness and plugging the body harness back into the bed harness.

If this does not fix the problem, the tail light circuits will have to be traced from the fuse all the way back to the lights to find out where the short is.

The trailer lights on your van should be fused independently of the vehicle lights if you have the factory wiring. There is a fuse junction block under the hood [should be in the left corner somewhere] and in that you should find the fuses for the trailer lights and other functions. This is from memory but check fuses #5 and #6, [10 amps fuses] and see if they are blown. I could be wrong on the numbers so you might have to check them all. Usually its the trailer that causes these fuses to blow so if you find a blown fuse replace it and make sure it doesn't blow again by testing all the lights with the trailer unhooked. If that's ok then hook up the trailer and check again. If it blows with the trailer hooked up then you probably have a short circuit in the trailer wiring somewhere. Good luck, hope this helps!

You didn't say if your trailer wiring was factory or after market installed so... look under the back end and trace the wiring from the tail lights. Look for a splice connection. There may be an inline fuse installed between the tail lights and the fuse block. Also look for a bad wire(s) which may have caused the fault.

Check fuse #6 20amp on your interior fuse panel it may be blown. The relays are located in an auxillary relay box located under the hood on the drivers side fender near the firewall. The system uses 2 relays. One relay turns on for left turn signal, other relay turns on for right signal. Both relays turn on for brake lamps. The fuse #6 is more likely the problem. If the fuse is blown, replace it, wiggle the wiring on the trailer while someone steps on brakes to check for shorts.

you have blown fuses from a shorted trailer harness, check all the fuses, both under the hood and inside the truck.

The truck is protecting itself from the load impose by the trailer.. Chk the plug on the truck for wire gauge size. Turn any electrical loads off on the trailer, any and all. If fuse still blows then the fuse is either underated or the trailer has a dead short. In fact turn trail main power panel of. All lights work you say. So ck the inverter for defect byturning off the inverter on one of the trailers.

fuse is underhood in power dist box.
if you only blow when hooked to trailer it is a problem with trailer wiring or light
