I tested the fan motors and both still work. I tested the relay and it still has continuity with no resistance. The rad fan fuse isn’t blown. I swapped the cooling fan module and it still didn’t fix anything. I’m stumped and I don’t know what else could be the problem. The only thing I could think of is a bad harness but there still seems to be continuity, at least to the black wire that connected to the module. Is there anything else that can be bad that I should check?
