Help !!!!!!!! Cooling fan

[fast-turbo]

Hey I need help with my fan. My fan will not run at all. even if I turn the air conditioning on it still dosent come on. I just replaced the low speed relay and I'm wondering if i need to replace the other ones as well. The weird thing is that if i just turn on the ignition switch and bypass using a piece of wire on the diagostics plug it will run. I have checked all otf the fuses as well and there fine any help would be great. Sorry i didnt replace the low speed relay i just replaced the coolant relay the big one. I did check the connections to the ecm and they are good should i replace the high and low relays just to be on the safe side.? Thanks for the help

if all your fuses are really good, then how about checking your ecm connections, the fan is controlled by that.

also
make sure your coolant temp sensor is functinoing properly, or it wont come on either (and you may not even se a SES light!)

Why not try putting power directly to the fan after disconnecting the plug up front near the resistor?

Jumpered fused 20amp. cord to the battery is a good first test of the fan motor.

I have the same problem. I changed all of the relays still nothing.
So i just ran a switch to run it all the time. But if you find the problem let me know.

Thanks Rob
