I have no reverse lights, I have checked and changed the bulbs before having it checked by a friend he said there is no power to the bulbs. Any answers?

Hi,

Check the reverse light relay, here is the location and the reverse lights wiring diagrams so you can see how it works.

https://www.2carpros.com/articles/how-to-check-an-electrical-relay-and-wiring-control-circuit

Check the circuits at the transmission range sensor. For the back-up lights. Voltage to the sensor, lite blue wire with pink tracer. In reverse, black wire with pink tracer carries voltage to back-up lamps. There is also a ground for the back-up lamps, you may need to check that also.

Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

I have a problem with my back up lights on a 2013 Ford F 150, you can put it in reverse with out starting the engine and they work fine, but when the engine is running they do not work.
