Radiator and condenser fans of my 1993 Honda accord work only when I turn the A/C on. I would like to know what the problem is. I appreciate any help. Thanks.

 

There is a two-wire thermoswitch A on the thermostat housing below and behind the distributor. You will need to pull the intake duct for access.

Remove the connector from thermoswitch A, short the two connectors w/ a jumper wire, and turn keyswtich to ON. Both fans should come on and run. If fans run, a failed thermoswitch A is confirmed. Replace thermoswitch A w/ new OEM unit.

These fans will only run when coolant temps is > 194F. I've found that many times the engine runs sligtly cooler than this and fans never come on. There is enough cooling air from forward speed to maintain coolant temp.

good luck
