Have a 2005 Ranger 6x6. Need a wiring diagram to trace out fan problem. Runs all the time, switch off or on. Can't find a relay or the sensor. Unplugged the one on the cylinder and it still runs but I think that one is the temp light. Any help appreciated. Thanks, TORK.

Thanks, I signed up and posted but have not got any replies. I have a cooling fan that runs all the time, even with switch off. Also temp light comes on when key is turned on, even with sender unplugged. Fan appears to be powered from the computer under hood but I need to know what tells it to kick on the fan. Don't want to buycomputer if it doaesn't need it. TORK.
