honda accord 94 fan doesnt run!!need help
honda accord 94 fan does not turn on while the car is on ,it turns on when its off(coolant temp switch okay),has new relay, new fan switch (thermastat housing) ,new ect sensor, fan works (tried the short circuit ) fuses check out.fans run when ac is on.needle goes all the way to hot, its some thing else, thermostat is brand new . what else could it be?

 

Do you have AC? Turn AC on and both fans should run.

Are coolant temps normal, needle slightly below horizontal when fully warmed? Neither fan will run if the coolant temp stays below 199F. If you have too cool thermostat or faulty thermostat, the fans may never come on.

Coolant Temp Switch A closes at 199F to cause the cooling fans to run. If car is reaching 199F and no fans, then Temp Switch A may have failed open.

good luck

Your temp switch A has failed open or, is diconnected, or broken wire.

good luck

 

fan switch i already replaced it twice , the fan run when i jump the plug 4 the fan switch ,so i dont think its the wiring

 

A/C on both fans work but still overheats: you may have a bad thermostat, bad radiator, bad water pump or blown head gasket.

chk this out, it will help diagnose the problem

 

What was location of the fan switch you replaced? You may have replaced fan switch B which controls engine off cooling.

good luck

 

the fan switch on the thermostat housing, the coolant temp sensor under the distributor cap have been replace ,the temperature sensor in the water outlet works sense the fan turns on when the car is off.also i dont if this matter but i took off the a/c condensor fan because the motor was blown.
