You blew a fuse. Check the in cab and engine compartment fuse box and replace burnt fuses. It's possible that you have too many lights on the trailer. This would cause a multiple amp draw on the truck pulling more power than the typical 10-25amp fuse supplied for trailers.

Hi Saddleback,

The brake lights on the trailer has been fitted with new tecknology. As soon as you apply the brakes the trailer brake lights will flash. This is let the cars behind you know that you will stop and they must keep their distance.

Can I tow a horse trailer using Class IV hitches?


Towing must be taken seriously and you must therefore make sure the correct towing accessories. A class 4 hitch cannot handle the massive weight of a horse trailer, it is therefore better if you didnt use it but used a class 5 hitch which can handle the loads.

Some people wire trailer plugs differently. If the plug is not wired differently than yours, make sure the tow ball is clean. No rust. That's where the trailer gets its ground from. Usually they will work if thats the case, but not right. I can't remember what the wire colors are right now. Go to etrailer and look up the diagram.

No brake lights on 2000 gmc 3500, replaced turn signal switch, all power good at fuse, replaced stop light switch, have directionals & 4ways & parking lights


Does it have a trailer hitch and wiring? If so, check to make sure connector is not shorted out and double check your fuses and/or replace fuse. It may look good but I've seen some that were burned out of inspection view. You might also want to trace wiring back to brake lights, just in case snow or build up pull connectors apart.
