I have a 07 Dakota 3.7L and I'm getting a check engine light and the code is P0527 it says it's a cooling fan relay module. I'm not a great mechanic and I can't find the cooling fan relay on the truck. Where is it located? And would this cause the AC to not work?

 

it's been a while for me and my dakota, but I do not remember an eclectic fan on the 3.7, even for helping when the AC is on. So there shouldn't be a cooling fan relay on the 3.7. the 4.7 has an auxiliary fan which kicks in to help with the AC, especially when at idle.
