yes, also the fan controller is under the dash on the driver side, if you unplug the temp sensor, with key on engine off ground the wire the fan should come on, have someone ground and un ground it for you while you find the clicking noise under the dash. if it clicks and the fan isn't coming on the fans probabally toast. test that buy jumping the fans pos/neg at the fan harness, it will spin backwards if you hook it up backwards.

Fan sensor is a single wire sensor in lower intake. Ground it fan should come one. This is on the 2.3 until they went to 8plug with the module on the passenger fender then the 2 wire ecm controls the fan thru that module.
