1993 f22a1 radiator fan will not turn on while the car is running

Ok so I have replaced the radiator,water pump,thermostat,new relay, upper/lower hose and all four temp switch. I can not get this fan to turn on at all while the car is running,but sometimes with the key off.

The car had been ran off a jump amd the fan turned on when the they key was turned on. Well I not one who like to rig stuff like that. I have spent well over 1100 on the cooling system and this is starting to get old. I am at a lose what els to check or do. I would rather not spend 2-300 at Honda or even spend another 100 to even think of a shop to look at this car.


What els would make this fan not turn on? Also the fan motor is good and will turn on if hooked up to the battery.


Sorry if any typo's I am having to do this from my phone



Thanks
Charles Kassed

yea you have a connection problem i would just hook up a switch hide the wires behind your trim otherwise put a funnel on top of your radiator opening pour coolant into the funnel even if the car does not take it down thats ok start it let it run with heat on full blast squeeze upper and lower hose every once in a while see if bubbles come up into the funnel i just had the same problem i had airbubbles stuck

coolant temp sensor is 15 bucks and may be worth looking at too but im counting on air bubbles trapped

Temp sensor was replace. All sensors are band new installed today. We have checked for air and spent hrs bleeding and lookingfor air with no luck. We can hear the relay kicking on ( sounds like a loud click or the a/c compressor kicking on) but the fan does not kick on. Also makes the ( click) with the car off when the fan should be kicking on the help cool off the matter faster.

Like I said all coolant sensors, radiator, water pump, radiator cap and hoses are band new. I am learning with an electrical problem or what about the fan control module? It's like an air plane the little black box you never really want to check lol

Re: 1993 f22a1 radiator fan will not turn on while the car is running

i noticed when i had my H23 my fan would only come on if the car hits 3 bars. other then that my fan never came on with normal temp. if your not overheating dont worry about it. back then i also changed the tstat, new rad, new rad cap, all temp sensors even jumped the fan to make sure it was working

Re: 1993 f22a1 radiator fan will not turn on while the car is running

Some more info about what's going on I left out. The radiator ran was rigged to turn on when the car was turned on and it would lock my thermostat stick closed and make me over heat. That why I have web putting it back to normal.

Also the car is overheating with the fan off. I did hook to wires up and ran it to the battery just to make sure the fan didn't go out. We are starting to think maybe the harness is bad. I mean the auto run with the car off has only work 4 out of 30 times.


Also is the (click) sound I hear coming from the fuse box the relay kicking in? We would like to check the head gasket, but with out the fan running it really does no good to replace it with the car still over heating.also the head gasket thing is just to play it safe the car does not smoke, no coolant in the oil and not losing any coolant
