There is some troubleshooting you can do but it could also be that the Hopkins Impulse 47235 you have is shot. Test the connection of the red wire (stop light switch) and also take a look at your connectors for corrosion and ensure you have good grounds.

If your controller does need to be replaced I strongly recommend going with a proportional controller which will provide you with better braking overall. The best option is the Prodigy P3 # 90195 because of its reliability, effectiveness and how easy it is to use. If you let me know the year, make and model of your vehicle and if you have a factory tow package/7-way or not I can let you know the correct wiring adapter for this (or any other) brake controller.

I have also added links to help articles on brake controllers and troubleshooting brake controllers for you to check out.
