How can I bypass thermo fan switch on honda accord 94

Have you fitted the thermostat in the right way around ,the body towards the engine ?

the thermostat could be bad ,not opening up to make the flow of coolant threw engine,you have switch on the bottom of radiator unplug the 2 wires with key on jumper the 2 wires if fans come on that switch could be bad or thermostat not opening to let coolant threw system

I would change the thermos stat and this should fix the problem...........Hope this helps.

Have you replaced the right switch that mean the switch with the right temperature according for this engine.

verify the plug of the fan and the fan switch located in termostat housing, if all are pluged in remove the conector of fan switch and short it with little piece of cable, if fan turn on replace the switch! it cost around $20. if the fan no turn on when short the conector verify if the fan conector have 12v if have it changer the fan motor if not check the fuse.

no its a sensor next to radiator its automatic turn on set temperature

open the hood of the car and you should see a black box with alot of fuses

Electronic thermostat is bad, or the sender is bad.

Hi

Bridge the fan temp sensor wires, if fan works, renew temp sensor.

Good Luck !
