SOURCE: cooling fans will not run
Most GMs use a relay package to turn on the fans. That is often controlled through a processor package. Very complicated...if yours is one of them. You will need Mitchell's manual or equal to trace this to see if you have all the signals.
SOURCE: cooling fan not working
The fans only run when the engine reaches approxminatly 235 degrees F. on the guage that is near the end of scale just before guage show "HOT" I don't think you have a problem, allot of folks out there don't know about this.
SOURCE: Cooling fan wont work
The water temp sensor is located near the thermostat housing. This sensor is what tells the ECM to turn the fan on/off. The water temp sending unit is located near the same area. You know you have the correct sensor is because the water temp sensor has a 2 prong plug. The water temp sending unit only has 1 prong.
