Had these installed and finally had the oplortunity to test them out . Every time they engage, the 3 amigos plus brake light also appear. I have the Wabco bypass but have not installed it yet. Will this fix it? Also, A/C blower was working fine when i took the vehicle in but has not worked at all since, not on high even. Is there something spevific that likely happened with a front/rear differential installation or do i just troubleshoot it as normal. there are lots of thread about A/C blowers so im sure i can figure it out although tips in that areq would be appreciated. IM using a bearmacht code reader and the amigos clear easily but reappear as soon as the lockers engage.

What actual faults are you getting?
I'm not sure on the specific faults. I want to say 4085 but that is a guess. Once cleared the vehicle would run fine again until the ATBs kicked in and then it was 3 amigos and red brake light. I apologize but didn't think to write down the faults. I will check my notes to see if I did. Resetting the codes worked and everything else worked fine. It was the first time out with the ATB's so I just attributed to them and know there is the shuttle valve bypass fix and I have that part. Sounds kind of dumb now that I'm writing it. I assure you, it seemed reasonable at the time.
