360 spider A/C Blower stop working

I check ECU, blower resistor and A/C control unit, I removed all and opened no burn marks or smell look ok, check fuses all are ok can't find relay for the blower, any idea what can be, thank you

 

Take a look at the resistor pack again. It's on the right hand side of the heater box under the dash. You will see four thin wires and two thick wires. The thick wires supply the earth to the blower motor, they are blue and black in color. if you connect them so the controller is bypassed and switch on the ignition, the fan will run at full speed if the resistor pack is damaged. They are a common failure....

 

I had an old one lying around, if you look at the photo in the link below you will see the two thick wires that you need to bridge to test the unit. Easiest way is to use a paperclip or split pin and bridge the two thick wires at the small white plug....

Also try unplugging and reconnecting the HVAC ecu bolted to the heaterbox under the left hand side of the dash...

 

yes the blower work after bypassing, can be repair or I need a new one?, thank you again

 

You need a new unit. They are a sealed unit, not repairable. Contact Daniel at Ricambi, who is a sponsor on here, and he will get you a new resistor pack!!!

 

With help like this on hand, F chat is just so awesome to be part of.

 

I replaced the blower resistor and still no luck but I find out if I connect the blue and black power connector on opposite way the blower work fine but is always on
