What causes both cooling fans to not run?


Hi Naomi , there is a lot involved in the control of the cooling fans on your vehicle ! There are three fuse's , three relays an a fan control unit !
1. radiator fan main relay , located in underhood relay box A
2.condenser fan relay , located in underhood relay box A
3.radiator fan relay , located in underhood relay box C
4.Cooling fan fuse # 47 20amp. underhood fuse / relay box
5.condenser fan fuse # 50 20amp in underhood fuse / relay box.
Any one of these could cause them to not work, rather then just replacing parts an wasting money you should take it to the repair shop !

1994 pontiac sunbird radiator fan not working


Unplug the coolant fan & put battery voltage, directly to it

If it works, in either direction, then get a wiring diagram
& work on testing the control side of the circuit

You can check all fuses, but replacing a blown fuse,
is not a fix, for anything, that caused it to fail

Radiator cooling fans won't come on. I can hook them both directly to a power supply and make them work, but not while they are installed. I even checked the sensor in the radiator. When I wire the...


Some cars have a thermostat that tells the fans when the water temp reaches a certain temp then the fans start. Or the relay that starts them could be bad. You may find the relay and switch it with another like it and see if that works.

MY 85 STANZA FAN WONT KICK ON AND I REPLACED THE THERM AND THE RADIATOR FAN SWITCH. STILL OVERHEATING AND NOW THE A/C WONT BLOW OUT VENTD


Possibilities include blown fuse due to too much fan current draw, faulty wiring, faulty cooling fan relay, check the cooling fan relay in underhood fuse box. the contacts may be burnt and sticking.

My cooling fan doesnt come on and car begins to overheat at low speeds?


Hello and welcome to FixYa! If you have overheating problem, it can lead to multipleissues. You may be running on low coolant that's why the vehicle overheats. Ifthat's the case, please add coolant and make sure that it sits on the rightlevel, too much coolant can cause overheating too for coolant will overflow. The vehicle may have a faulty or worn out radiator blowermotor that's why it overheats. If that's the case then you will need a blowermotor replacement to resolve the issue. If the radiator is clogged with dirt and rusts this issueoccurs too. The coolant doesn't flow normally on the cooling system if it'sclogged. If that's the case, I strongly suggest that you have the radiatorflushed to drain out dirt and rusts. If you think that the radiator served youenough then it's better to have it replaced. Please do check the radiator hoses, If you have worn outhoses it can cause coolant leakage which can result to overheating. A tiny holeis good enough for the vehicle to overheat. A faulty thermostat sensor can cause the issue too. If youhave worn out thermostat, the fan may not trigger that's why the fan won't workwhen under stressed conditions. A blown radiator blower fuse can cause thisissue too so I suggest that you check the radiator blower fuse and replace itwhen necessary. What causes the radiator blower fan fuse to blow? It's becauseof a failing radiator blower motor, If that's the case have the radiator blowerfan motor replaced. If the fluid in radiator doesn't circulate then it meansthat you have a blown head gasket or a faulty water pump. I suggest that you gofor the water pump replacement first specially if you think that it's near theend of it's service life. Usually, water pops out the radiator when engine isreved (a sign of faulty water pump and possible blown head gasket). Hope you find this information helpful enough and thank youfor using FixYa! Have a good one!

Continous cutting of fan even after changing alternator and related purlins. So what is the problem?


Check these parts........... First check the TEMPERATURE/RADiATOR FAN SWiTCH, it is connected on ur RADiATOR, w/ 2 wires connected to it, at certain temperature the switch turns ON ur FAN MOTOR, by disconnecting it and JUMP/SHORT the 2 wires FAN MOTOR should run, even when u just turn on the ignition! If the FaN runs, u got temp switch prob and needs to replace, If the fan didn't run when u shorted the wire in the switch. Check the RELAY, located in the ENGiNE FUSE box, pull out the relay and replace it w/ another relay, while ur 2 wires in the temp switch is on and ur ignition is in the ON position, when the relay clicks and the fan runs, u have a GOOD relay, if not u have to replace the RELAY! Hope that explains everything! Taah!

Engine fan does not turn on


Look on the radiator for a switch (Physically screwed into the radiator) with 2 terminals on it.

Pull them off and short them together with a piece of wire. (Jumper) If the fan runs your thermostatic switch is bad.

The switch is a real common failure.

If the fan does not run... check the fuses.

If fuses are ok then check the fan winding for resitance with an Ohm meter.
No resistance = burned out fan motor

Thanks for using FixYa!
