Hello Gerry. A blue and red light on the Blue Ox Patriot # BLU37TR means there is too much pressure on the brake pedal. Try to see if you can move the unit back from the pedal until the lights start blinking blue and green in sequence. Try to adjust the push pads up or down to get better contact with the drivers seat, making sure the back of the brake unit is resting against the front of the drivers seat.

You could've hit a bump in the road that knocked it around and is causing the load cell to detect pressure when it shouldn't. If the issue persists I do suggest you reach out directly to Blue Ox.

@Gerry Was is because the unit was faulty or that they also could not figure it out? Having the same problem with mine. It has worked perfectly in every trip we’ve taken until now. It sat for 1 1/2 years. Could that have caused a problem?

First question I am having a problem getting the brake to set up ,, first question, I have the brake hooked up. Do I need the tow vehicle to Motorhome plug hooked up to troubleshoot?

@Jan No, not necessarily since the brake unit is powered by the towed vehicle battery. Are you setting up a new Patriot unit? What problems is it giving you? Let me know.
