Hey guys. New here. The only posts I have are related to responses about what I'm about to ask. My truck has a P0481 code for the cooling fan circuit 2. It doesn't look like the main fuse box has a relay for the cooling fan, but from what I'm reading there is a relay controlling the fan located somewhere else. Where is it located so I can check it? Also, my blower motor resistor seems to be going bad since the 2nd speed on my AC selector switch doesn't work. The other 3 do. I have ordered a resistor, but also wonder if that could also affect the cooling fan from coming on? I can clear the code and the fan does come on sometimes, even for a few days before failing again and throwing the code again. The fan works when it does get power, but when the CEL comes on there is no power going to the fan so I'm assuming the relay is bad, not sending power past it or if the resistor affects operation, could be that. Any help is appreciated.
