The line is continuity... it completes the ground signal back to the pcm. Then the fan is turned on. Problem most likely, connector needs replaces going to sensor... common problem. Be watchful when placing new connector on once you have spliced the new one on, since there is only one way that it fits in and might cause damage if forced in the wrong way.
SOURCE: over heating
Yep, you have to burp the radiator. Jack up the car so that the radiator cap is elevated. With the coolant topped off, start the car and let it run until it's about 3/4 of the way to overheating. Then shut it down and go have a beer. When it cools off enough to safely open the radiator cap, do so, and any air trapped in the system will bleed out.
What you're doing is circulating the coolant and the air bubbles inside. The bubbles get lodged behind the thermostat and stay there, keeping it from opening (this causes the car to heat up). When you later pop the cap off the radiator, the pressure is vented from the system, the thermostat opens, and the bubbles pass through. They'll work their way to the radiator (since you've got it elevated) and pop out the open cap opening.
Your coolant level will likely drop somewhat after doing this, as the air bubbles will be gone and the space they took up in the system is now available. You may need to add a little more coolant, so top if off (with the car back on the ground) and recap the radiator, fill the overflow to the marked point on the tank, and you're good to go.
SOURCE: radiator cooling fan 30 amp. fuse keep blowing
The fan may run with jumper wires but if it''s blowing the 30 Amp Maxifuse it's needs a new or used fan motor.It's pulling too many amps.I have almost never seen a fan relay concern.Only other thing you may check is the wiring down near the fan shoud I have seen the 2 wires get loose from the conduit & melt onto exhaust manifold.Hope tHis Helps
SOURCE: 1996 saturn sl2 fan coming on late an over heating
Start with engine cool, & remove radiator cap. Check level in rad & fill to an inch or so from top of rad. Start car & turn heater on.(not defrost)
Now let it run until engine gets up to normal operating temperature & let it run until rad fan comes on & off, 2 or 3 times. Rev engine slightly every so often just to help disperse air in system faster. Fill rad as needed during this time. After you do that, and fan has come on & off 2 or 3 times, put rad cap back on & fill return bottle to proper mark, then see how it is.
I suspect it's just air in system & this should cure that . If not get back to me.
SOURCE: Saturn 2002 sl - heat suddenly not working. Friend
replace flow control valve. theres a switch that allows the fluid to flow into the heater core this is what im saying is the fault. try that my next suggestion would be to replace the heater core.
SOURCE: 1996 saturn sl 1 runs hot change thermostat temp
check head gasket it might be blown this will cause overheating to
