Engine cooling fans on 1997 Olds Aurora do not work

Does anyone know what can be wrong? I have checked the 10amp fuse under the back seat and the 60 amp one in the engine compartment. Please help

    the engine cooling fans do not turn on when they are supposed to. ie, when the engine temp is getting high none of the fans turn on to cool the engine. And when the A/C is on, when i request defrost, the a/c clutch does not engage and of course the engine cooling fan does not turn on. Hope that explains it a little better

    it does have dual fans, I checked the relays and they are both good I also checked the low speed relay that is on the fire wall by the ww motor.

    The rad is hard to see I will look again. I did find a sensor in the rear of the right head, did not have a chance to see if it had an open circuit or not. I imagine that the resistance should change as the temp changes, telling the computer to turn on the fans when the resistance gets to a point. Thanks for the help. I will check this out and let you know what I find.

    Cooloing fans do come on but not until gauge reaches 225*, which by that time loosing antifreeze. I have replaced both relays and 60 AMP fuse - no change. Has dual fans- both doing same thing.

    Not having much luck finding wiring diagrams on the Aurora so lets go this way. Do you see any sensors on or wires running to the rad near the side or bottom, that could be considered a temperature relay or switch? I know some vehicles incorporated a sensor/switch right in the rad, that when it reached set temperature, would complete connection, thus fan would come on, and off.

If equipped with DUAL fans I would consider the fan relay switch should be under hood in the same compartment as fuses this would be the first place I would start

Where is the cooling fan control switch on the 1997 olds aurora V-8?


There isn't one. The computer uses the engine coolant temperature sensor for both fuel delivery data and fan activation. If you turn on the A/C or pull the coolant temp sensor connector off while the engine is running, the fan(s) should come on. If not, you may have a bad relay or fan motor.

2001 Olds Aurora. The fan is blowing but very little heat is coming out. Maybe 60 degrees tops. Where should I begin my trouble shooting to see what needs replacing?


First check to see that the cooling system is properly filled.
Next, watch you engine temperature and see that it hits operating temperature. If the thermostat sticks open the engine will never get up to normal temp. On my Aurora, that is exactly midway on the temp gauge.

1996 olds aurora cooling fans don't work


is it blowing a 40 or 60 amp maxi-fuse located on the passenger side front area of the engine compartment located in the fuse panel? If so i believe 95-96 had the wiring for the fans to close to the exhaust manifold causing the insulation on the wiring to melt which in my case resulted in a dead short off and on blowing the fuse.

Cooling fans will not come on my 1997 olds aorura


This could be a lot of things,check the fuse for the cooling fans,then check the coolant level,and if there is air in the cooling system this will happen,and of course the coolant sensor could be at fault,and the cooling fan relay.

Olds Aurora seat wont adjust


Check on the side of the seat for a manual lever. For some reason the car companies still include a manual adjustment in addition to the electric one. If any direction works with the motor then the fuse is good.

Cooling fans wont come on with out the a/c


First check all your fuses in both the under hood (60 amp) and right rear (10 amp) fuse blocks. Remove the low speed fan relay (in the under hood fuse box) and install a jumper across terminals #30 & #87. These are not marked on the box, but you will find these numbers identifying these terminals. With power at the #30 terminal, installing the jumper wire will send power directly to the primary fan. The fan should now run, if it doesn't, check it's ground wire, if that's OK, replace the fan.

97 Olds Aurora power windows don't work


The fuse that you are Looking for should say "PW" for Power Windows. If it is not good there is a Relay in the Box under the Hood for the Same thing. Change this Relay and they Should Work. Please Rate my Response, I need all the Help That I can Get! Thanks!
