got a question guys i got a check engine light for the cooling fan relay and i changed it and the light came back. the only other thing that came up is that it could be the connector or some wiring problem. has anyone had this problem before?

As rbarrios hinted at, there's a chance for chafed wiring in the harness going to the fan clutch, the unit connected to the fan. There are four wires in a plastic channel leading to the driver's side of the fan shroud. Disassemble that area and look for damaged insulation. Could also hbe a fault inside the fan clutch.
