I showed him a service bulletin that said BCM was at fault for intermittent fan failure. They kept the car one more week replaced the BCM and fans are now fully functional and operate as they should. Best part is he saw us pull up and brought the keys out to me and again apologized for being an "ass hole" ( my wife and children were present) and that he backs his mechanics and they have never seen a BCM cause these issues. The bill for the BCM....NO CHARGE! he shook my hand and said he hoped that I'd still consider them in the future for repair work. If I can figure out how to attach the information on the BCM bulletin I will add them to this post.

I'm kind of surprised and disappointed at the dealer for not finding this info to begin with. A quick bulletin search with your vehicles info, searching cooling fan, and the TSB pops right up. Should have been caught the first time in. Weird how you say that with low speed fans not running that the a/c didn't cool until there was sufficient air flow over the condenser. Some people don't think that cooling fans affect a/c operation.
