my radiator fan won't turn on in my 88 Si...checked fuses...theyre good..checked the plug ins(green ones) dont know what's wrong? i'm a noob to crx's help me out please!!!

 

ok...easy to check the fan motor unplug it and stick a wire on each prong and put them on the battery terminals...if it turns on its fine...the other could be the relay...follow the wires from the plg to the replay, follow the manuals directions on how to tes the relay...then finally the sensor for the fan...OBD0 motors it on the back of the block kinda of near the oil filter and on OBD1+ motors its on the thermostat housing...make sure the plug is connected and the wires look ok...its a very simple system it works on its own without the ECU being involved so its any of the following:

Bad Fan Motor
Bad Relay
Bad Sensor
Bad Wiring

 

thanks alot!! i'll check it when i get off work

 

I've lost a couple relays to old age, I now have a collection from the local salvage yards
