Turn signals don't work. Checked fuses, OK, checked bulbs, OK. What next. 2003 Lincoln town car.

It sounds like you may have overloaded and burned out the flasher relay. On most cars, this is a small 2 or 3 pronged cylindrical unit. On some Fords I have encountered, it is way up under the dash and actually has a relay with other circuitry. Consult a specific auto manual for location and access if this is the case. In most cars the factory installed relay can not handle the load of the additional trailer lights and will cause them to flash irradically or fry the relay. There are heavy duty relays available for these applications

2006 Saturn turn signals on right side don't work

May want to check the bulbs on the trailer to ensure the connections are solid and the wiring is in tack. May be a weak ground wire connection.

I have a 05 silverado all three break lights do not work. When I hook up my boat the break lights on my trailer function just fine. And all bulbs and fuses are good any ideas.

Have you checked the bulbs? Some people don't beleive all the lights can burn out at once but when one brake light is on they are all on and for the same amount of time.
If the bulbs are fine then check the connection where the trailer plug is to the main harness. Some of those connectors go between the main harness and the tail lights and the connector can go bad.

We have a 2003 f250 super duty. We have no power

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.

Do the 2009 Nissan Frontiers have a turn signal flasher? I had a 2'' ball hitch installed and when attaching the boat trailer to the hitch the trailer turn signals don't work. When they hooked up the boat...

check for signal ground,this is not a metal ground, use a test light or volt meter to see if they at plug before you plug in the trailer, you may need to rewire the trailer.

Fuse for trailer right turn signal and brake blows intermittently

abad ground on that tail light unit could affect current load when turn and stop are used simultaneously. Although one side only is affected make sure of good grnd between trailer and tow vehicle. focust on the tail light unit in question. Replace the bulb. though rare, bulbs have been known to be the problem. If the bulb is breaking filiments ck the filiment orientation. filiments last longer in vertical orientation, where horizontal permits vibration to break the heated filiment when brake is applied.. good luck and let me know if This helped or not.

No running lights on boat trailer towed by 2008 ford f150

You can purcahse a tester which will connect into the F-150's wiring harnes. If the led lights up, the problem is witht he trailer's wiring harness. this tester will indicate the proper operation of the brake light and turn signals.
