The most common cause of failure is the 7 pin plug and connector between the truck and trailer. Check the contacts on each for bent connectors or corrosion. (I've been able to resurrect a trailer connector in the past by gently bending a prong back into place with a flathead screwdriver, but with a trailer so new yours shouldn't be that worn.) CAUTION: Pin 4 on both truck and trailer may be "hot" (connected to the battery) at all times in some installations, so don't short that one out.

A "Q-tip" to help clean things out and then some dielectric grease - you can put that in the trailer plug with another "Q-tip".

Past that - check your fuses.
