There is a recall that could have something to do with this, I would contact CC, they do have a technical support number, I would think there is a strong possibility with this recall it could be the issue.... Robert

Let me go through my notes, I actually was at CC in 2005 and recall the circuit breaker change out but do not recall an issue with the brake circuit, I would want to verify all the breakers are the correct type as when they heat up they should trip I was thinking heat related and tow vehicle, let me see if I can find anything else out... Robert
I would see if this has a tow card, or tow board and check the connections on that board, if that board failed it could cause the brake lights to fail even if the tow vehicle is not hooked up. I would think CC would have checked that to make sure it is not the problem.... IF you like I can put your question back up for other experts..... My goal is for you to be satisfied, questions like this are always a challenge online.. Robert
I am not so sure the tow board could back feed the brake circuit as it is tied in with it. I will put your question back up for other experts, maybe another expert has seen this before, I do not know when another expert will respond, they come and go daily, If I can think of anything else at all I will jump back in.....
