Question about Cars & Trucks

1 Answer

92 Honda accord. Radiator cooling fan does not turn on. All fuses were checked...Ok, Replaced both A and B temperature switches. The A switch, located at the thermostat housing was tested by putting it in hot water. The switch closed at round 120 deg.f. Placed a jumper across the A switch connector and the fan turned on, but when I put removed the jumper and connected the switch, fan never turns on (engine was turned on and allowed to heat up). Everything shown in the fan motor circuit was replaced or swapped with another part...or tested directly with no explanation. Any more ideas...I exhausted.

If bypassing the sensor in the car allows the fan to start, then I would say the issue has to do with the sensor. I've heard of them getting an air pocket around the sensor and preventing the fan from coming on. Maybe the contacts aren't making up in the connector? Corrosion could be causing an issue. Maybe a loose wire that opens the circuit when plugged into the sensor.

SOURCE: cooling system

hi jackie,

you could have a short in the wiring of the temperature sending unit. this would answer your second problem,
for your first problem of coolant will not circulate through the engine, may i know how did you know that the coolant is not circulating?

the fan will not run unless the coolant is hot enough, and you told us that the coolant is not even hot.

SOURCE: Radiator fan not working

Hi. Check the bottom of the radiator or on the side, as you also have a temperature-sending switch. The switch must reach a certain temperature before sending a signal on to the fan relay.

The switch just screws into the radiator.

If you would like to contact me again about this or other problems, feel free to do so.

SOURCE: OVER HEATING

In the fan circuit...You have a temp switch screwed on the radiator, a fuze and a relay in the fuze box plus a fan.  Swap the relay with another relay, replace the fuze.  The other fan should come on when the a/c is turned on.  If you fix the fans and it still overheats, you may have a BLOWN HEAD GASKET.  ALSO ARE YOU BLEEDING THE AIR FROM THE SYSTEM?  DO YOU SMELL EXHAUST IN THE COOLANT?

SOURCE: Radiator fan not working

The cheapest and direct solution is to run a hot wire to the fan motor that comes on with the ignition. It will run whenever the car is turned on. This does not "fix" the problem, but it will keep the car's engine alive.

My 2000 honda crv is overheating there are 2 fans and neither seems to come on


One fan should come on when the A/c is turn on. The other fan Will be the primary radiator cooling fan. This fan is controlled by a coolant temperature switch, a relay and fuse. Once the coolant temp, reaches 186 degs. the fan should come on. So you have to check the fuses for a burnt fuse, then you can check the coolant switch by un-pluging it and making a jump in the wiring with a paper clip and stick it into the connection. That should force the fan on. Hope this helps FixYa up.

I would have it checked for a blown head gasket. Combustion gasses in the cooling system can keep the temperature switch for the fan from operating properly.

Have a 1994 honda accord, no heater blower motor inside of the car and no cooling fan motor at radiator . Are they tied together by a relay or fuse? Why do they not work?


I think there is a fuse box under the hood and also under the dash. Check the fuses.
Make sure you get the cooling fan motor at the radiator fixed asap! I had a 94 accord and didn't know that one of the 2 motors went out. When the second one went out my transmission fried. Very costly!

Check for a faulty engine coolant temperature switch. This is the switch that talks to the cars computer and the fan relays. (It is NOT the same as the separate coolant temperature sender which is what sends the temperature to the coolant temp gauge on the dash instruments.) If the engine coolant temp switch is stuck open or in the cool mode, it may not trigger the fan relays. Meanwhile, your coolant temp on the dash gauge will look normal.

REPLACED MOTOR AND STILL OVERHEATING WHAT'S THE PROBLEM? CAR HAS NEW RADIATOR


Did you replace the fan? How about the fan switch?

Here is some stuff to read about this system....please let me know what's up!


This switch is the primary controller of the operation of the radiator fan(s) used for cooling. When the coolant in the system reaches a pre-determined temperature, the fan switch closes and completes a circuit. The fans will be brought on. Generally, the switch communicates with the fan relay, although the later PGM-FI cars send the signal through one of the many solid-state controllers first. Do not assume that the switch is the only component in the radiator fan circuit which controls its operation. There are many other components whose failure may prevent the radiator fan from operating. If the fans are not working when the engine is very warm, check the fuses first.
On all vehicles except 1990-95 Accords and 1992-95 Preludes, the fan switch is located in the bottom of the radiator. On 1990-95 Accords (except V-6) and 1992-95 Preludes, the switch is located in the housing at the rear end of the coolant connecting pipe. This is the pipe running along the outside of the engine, just above the oil filter. The switch the only electrical component in the housing. On the Accord V-6, it threaded into the side of the coolant crossover pipe (not next to the bleed bolt) on the transaxle side of the engine.

92 accord radiator fan not working


the sending unit has went bad. it comes on with the ac because it designed to overide the high temp sending unit or switch. should cause less then 50 bucks to get it replaced and only a few bucks if you do it yourself
