poor ground wire
You have a grounding problem at the trailer. The white wire is the ground on trailer wiring. The taillights are brown, the signals and stops are yellow and green. Sometimes the white wire will loose its continuity with the truck, causing the lights to black out. It could also be a wiring issue with the trailer itself, but most likely its the ground giving you feedback and causing the blackout. run a wire from the ground contact on your plug back to a spot on the tongue and secure the end of the wire to the trailer at that point. Do not rely on the contact of the trailer with the ball hitch to establish a ground.
There is a connection issue between the trailer brake controller and the trailer.
If there is a trailer wiring harness on the vehicle for towing unplug harness under drivers side rear tail light to eliminate the trailer wiring that's probably the issue then plug factory wires together
There may be an issue with the relay switch going to the radio lights. There may also be an issue with the fuse.
Changing head bolts is never a necessity, unless you have an issue with bolts breaking etc.
1) I've learned more than anything to unhook the lights before backing the trailer into the water. Nothing like a hot bulb meeting cold water.....but if you believe the advertisements, boat trailer lights should be waterproof and not let water into the space where the bulb is. RIGHT !!!! 2) Now, the other issue that has to do adequate grounding usually needing more just the hitch ball. - inadequate grounding is the number one cause of trailer light problems and cause all kinds of strange behavior (work sometimes, or only when headlights are off, or both sides flash with either blinker, etc.) - try a better ground than the tongue and checking for any corrosion at any of the individual light ground connections (which tend to corrode over time).
Pulling the trailer is not a problem the issue is stopping it with the xterra. = ask yourself == Does trailer have brakes? Surge or electric will be needed.
If you do not have working tail lights on your GMC vehicle it may be an issue with the wiring or your lights may be burned out.
Try adjusting the dimmer on the control for the dash light. If ti were a fuse, you would have no lights and that would never be a bulb issue. How's your alternator??
Nothing good. Tighten the bolts and this becomes a mute issue.
There can be several common safety issues involved when one is installing a hanging pot rack. The primary safety issue would be hanging a pot rack on a surface that cannot support the weight. Another issue would be pots falling from the rack and causing injury.
Yes! i have towed many times with a Honda Element. The real issue is weight though and I would not put more then 1000lbs in that trailer.
