I Have A 1994 Saturn Coupe And My Coolant Fan Is Not Working Saturn mechanic: mr. edc. disconnect the coolant temperature sensor, and make sure there is 5 volts (or real close to it) on the yellow wire. voltage drop the grey wire, and it should have no more than 500 millivolts drop on the ground. if those two tests are ok, then verify the integrity of the wiring to the pcm. Usually a faulty cooling fan relay will produce a few symptoms that can alert the driver that service may be required. 1. engine running hot. one of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats. if you notice that your engine is running at higher temperatures than normal.
Q A 1994 Saturn Sc1 Sc2 Sl2 Cooling System Issues Normally the. radiator fan will come on when the a c is on or if the temp gauge reaches. 1 2 way. in this case neither happened. in testing the components both the. fan and the a c compressor work when 12v is applied directly to them. the. car has a single coolant temp sensor so the temp gauge would not work if the. Member. 1994 saturn sc2. 4 cyl. automatic. 120,000 miles. i have replaced coolant sensor and relay, fan still did not come on. so i used a wire to jump the sensor plug wire so the fan would come on when i turn the ignition key on then off when i turn the ignition key off. the fan would work then. thursday, november 21st, 2019 at 9:16 am. The most common causes of why a radiator fan is not working are a blown fuse, a bad relay, or a broken wire. it can also be caused by a faulty coolant temp sensor, low coolant level or the fan itself can be damaged. while these are some of the reasons, the list is not exhaustive. here is a more detailed list of the most common causes of a. Connect the motor directly to 12 volt power with jumper wires to see if the fan spins properly. if it doesn’t, the motor is likely burnt out. check the coolant temperature sensor. a signal from the coolant temperature sensor is what triggers the ecu to turn on the radiator fan, and if it’s faulty, it can prevent the fan from working at all.

As far as your 2000 sl2 sounds like you need a new coolant temp sensor.when the coolant temp sensor goes bad it alway's read's too cold so when they go bad the temp gauge still work's it just never turn's the fan on when it should and the car over heat's.replace the coolant temp make sure you get a brass tipped one the plastic tipped one's crack.you will loose coolant also inspect the. Since you said you replaced the temp sensor, then i would check the fuse first. if the fuse is still good then i would check the fan relay. there is a fuse looks like number 6 in the uhjb. there is also the cooling fan relay is in the underhood junction block (uhjb) . the uhjb is located on the left inner fender in the engine compartment.
