Blown fuse.
If there is current going through the wire to the blower switch, try bypassing the switch with a jumper wire. If the blower motor works, then replace the switch. If the blower motor does not come on, then you probably need to replace the blower motor.
The blower is controlled by the blower switch, blower resistor, and relevant power relay.
Check to see if you are getting power and ground to the blower motor - if so blower motor is bad. If no power possibly fan switch or selector switch Also check the blower motor resistor, found in heater plenum.
Check the fuse
Check the following................ 1. Power and ground to the blower motor. 2. Blower resister. 3. Blower switch.
Check the fuse. Check the blower speed resistor. Check the blower speed control switch.
fuse or relay most likely
blower motor bad or no power to it chech fuses blower switch blower motor
Either a broken wire - faulty switch - or bad ground. You're going to need a test light to find the fault here. Is there power to the hot side of the blower switch? Does power transfer to the cold side when the switch is turned on. Is power reaching the blower. Blowers rarely fail BUT it can happen.
Check for melted wires at the ignition switch. The blower motors go bad, draw too many amps, and melt the ignition switch and wiring.
Blown fuse? Bad Relay? Open wire?
probablly a bad ignition switch or blower motor not sure on that should run without power
