Replace the fan relay in the fuse box in the engine bay first. Fan motors very,very rarely go bad. Check the relay first, you may save yourself an a lot of time and money. It may also be a bad coolant temperature sensor or a bad connection and/or bad ground.

Acura legend ac control untied stop working along with the fans any idea wat could it be


The rotary control switch on the dash controls the blower motor for the A/C. The A/C will not turn on unless the blower motor is functioning properly. The passenger-side radiator fan will not turn on until the A/C begins running. BUT the driver's side radiator fan should always work. Ergo, check the function of the blower motor (located underneath the dash behind the glove box). Usually when it goes bad, it's because of the blower motor RESISTOR (mounted inside the blower motor housing). When the resistor goes bad, the blower motor shorts out, causing it to fail. The switch rarely ever fails. The radiator fan relays are located next to & on both ends of the radiator. Check them too. In the link, the blower motor RESISTOR is #5.

I have a 1988 camaro iroc with the fuel injected 305, my radiator cooling fan doesnt work and i just replaced the fan motor. Could it be a bad relay or bad ecm unit??


Well, yes and no.
Yes the relay or the computer could be faulty.
But the computer is not going to ground the relay until the engine temp reaches about 225 degrees.
Since the thermostat opens at 195 degrees running at 200 is normal.

Cooling fan(s) wiring diagram


Its either t Cooling Fan Switch ABCDEFGHIJKLMNOPQRSTUVWXYZ Inspect/Test/Replace

To find the RADIATOR COOLING FAN MOTOR RELAY, we need additional information about your 1995 Oldsmobile Aurora 4.0L SFI DOHC 8cyl.
Please select one of the following:

The Radiator Cooling Fan Motor Relay is located: Under hood, passenger side, upper firewall, mounted in corner in relay block
When testing a cooling fan switch, first test it with the engine cold, then test it when the engine reaches a specified temperature. Check your vehicle's service manual for more directions.
To check a switch, disconnect the connector at the switch. with an ohmmeter, check for continuity between the terminals of the switch with the switch moved to the on position and to the off position.

Please select one of the following:

The Radiator Cooling Fan Motor Relay is located: Under hood, passenger side, front side of wheelwell, mounted in relay panel
The continuity through a switch can be checked with an ohmmeter. With the switch open, there should be infinite resistance. With the switch closed, there should be zero resistance. With the switch off, there should be no continuity between the terminals. With the switch on, there should be good continuity between the terminals. If the switch is activated by something mechanical and doesn't complete the circuit when it should, check the adjustment of the switch. (Some switches are not adjustable.) If the adjustment is correct, replace the switch. Another way to check a switch is to simply bypass it with a jumper wire. If the component works when the switch is jumped, a bad switch is indicated.
Voltage drop across switches should also be checked. Ideally, when the switch is closed there should be no voltage drop. Any voltage drop indicates resistance and the switch should be replaced.

Fan dont work but when i turn on cooling system two fan work please give me lay out for cut-off and fuse


If you have two electric fans the fan on the passenger side of the vehicle is the radiator cooling fan, that fan should run when the motor gets to hot. The fan on the driver side is the ac condenser fan that fan runs only when the a/c is turned on. The only time that both fans run is if the a/c is on and the motor or coolant is above normal tempeture.

Engine heat get high & whats kind of fan radiator suitable


i am familiar with the car and the problem . the best thing to do is go to the local parts store and ask for an adjustable thermostat fan switch its about 40 dollars you wire it to the battery the fan and a ground mount it near the battery start the car and adjust the knob to the desired fan turn on temp . to fix the setup you have there is a fan turn on temp switch on the passenger side head toward the rear should have one wire on it that grounds the relay on the radiator support . 87 should have one fan one relay sometimes the relay burns and melts the plug you have to buy a replacement plug from a parts store along with a relay so to test it ground the sensor wire with the key on and fan should turn on if it does that's the problem you could also buy a low temp one from summit racing.com the fan will turn on sooner if it still wont turn on the relay is the next culprit check if you have power and a ground with key on at relay plug if you do the relay is bad change it . hope this helps

Fan has stopped working causing over heating, what is the most likely cause


There are 3 possible things;
The fan motor itself
The coolant temperature switch, which operates the fans, usually screwed into the engine block near the thermostat housing. Have to drian radiator to change it.
The relay-- It's a small black square shaped object, some are located in the fuse box in the engine compartment, and some are mounted on a bracket on the firewall, passenger side.
Could be in the wiring that connects these components.
To check the fan motor----- disconnect the wire plug from the fan motor, use jumper wires directly from the battery to the connector on the fan, If the fan works, then either the temp switch is bad, the relay, or the wiring.If the doesn't work, that is bad and needs to be replaced.

Fuel pressure? Do you hear the fuel pump running? Read the codes to see if ECM is still alive. Do you have spark at the plugs? Remember all motors need 3 things to run air, fuel, and fire at the right time.

Passenger side radiator cooling fan stopped working


I found that for some reason if you start your car and then remove and reinstall the hi and low relays that the fans work. I have done this numerous times on my 1995 lhs. I thought that my fans were defective until by chance checked the relays which engine was running.

Backfiring 90 iroc z


One fan is for when the vehicle gets hot , the other for when you are running the ac. I am more concerned with your drivability problem when it gets hot and the reason it gets hot. one fan not running won't cause this. Due to the fact that it is backfireing and your speed is reduced, I wouild be looking at a possible pluged cat.
