The fan clutch does have an electrical connection. The wire loom comes out of the fan clutch, runs down the back side of the radiator, and makes a connection underneath the fan shroud near the driver's side of the vehicle. According to my mechanic the fan speed varies with temperature and engine rpm, all monitored by electronics. Mine failed recently and it was a $500+ fix, including labor.

stumped-i checked the plug to the fan-everything good. unsnapped it-looked brand new inside. fan turns freely when truck is cold-dont feel any play. buddy of mine plugged in his snap on scanner last night-obviously code p0217 came up-said something to the affect of-check integrity of the cooling system-where to next?????
