Thank you all for the replies and great info.
After testing, checking, and then speaking with Freightliner in Gaffney, SC, I think we have narrowed it down to the Hydraulic fan control module (this is the part that I had found that the bolts had came out and was in two pieces, with the front piece dangling from the wires. I bolted back together but still didn't work).
My next question is, does anyone know where I can purchase the part besides Freightliner? Freightliner of Utah quoted me $800 and said it would need to be shipped from Reno.. The part is a Sauer Danfoss #1090385 hydraulic fan control module.
Thanks again for all the replies and great tips in helping diagnosis the problem.
