What brand and model brake controller do you have? We need to look it up and see how it interfaces with the truck
If the manual button applies the brakes on the camper, that helps tell the trailer brakes have some level of working, the wire out the back of the truck has some level of working and the controller has some level of working.
Pending what type and brand/model controller you have, some use the brake pedal switch on the truck to send a signal to the controller to start timing and when to send more power to the brakes. Other controllers do not use that signal they use an internal inertia system that senses the truck movement when braking. We really need to know what brake controller you have and how it interfaces with the truck.
You may have a wiring issue off the truck brake pedal switch not sending a signal (assuming your controller even uses it. ) to the brake controller. While the truck and camper brake lights work, that does not always mean the controller got the signal. And it may be the controller is having issues.
Ideally link us the controller brand and the manual. Does you manual have any fault codes as indicated by blinking or lack of blinking lights?
Hope this helps
PS. Caution when pulling the emergency breakaway switch with the 7 wire cable still plugged into the truck. Some brake controllers do not like power coming in the 7 wire cord from brake wire from other systems. It can back feed the controller. Just unplug the 7 wire cable and then do the emergency brake away test.
