The blower motor is the key to pumping in the air and if it's spent, nothing will pump. I would try replacing that first.
AnswerOn many mopar products there is a defrost resistor (I think that's what it is called) located on the passenger side on the very top of the firewall. This provides heat to the defrost vent system before the engine can deliver any heat. Sometimes one of the heater coils wil break or becom disconnected. If you remove the part the broken part should be apparent if not test the leads with a ohmmeter for continuity. AnswerI had the same problem. The wire to the heat, etc., fell behind the fuse box, so we ran a separate wire to that fuse, and it works like new.Have you checked the fuse and relay? - They are in the engine compartment above the passenger strut.
It doesnt.
because it doesnt like you
Blown fuse, bad motor, bad blower motor switch, or a defective Blower Motor Resistor Pack.
if it doesnt work on 1 and 2 it could be a blower motor resistor but if it doesnt work at all check the fuses, relay and check voltage if it reads 12 v replace the motor
Bad blower motor? Blown blower motor fuse? Bad fan switch? Bad blower resistor pack?
Resistor or blower motor power module.
Inspect the backside of the blower speed switch. Look for an overheated, melted plastic connector. Loose connections causes resistance, resistance causes heat, heat causes melt down. Look for melted connections at the blower motor and resistor also.
check the blower motor resistor located on fire wall behind washer fluid tank
it doesnt. you should get that checked it may be a problem with the relay
the blower resistor is bypassed on high. a direct path to ground. if high is the only operational speed the resistor is bad.
A Ryobi leaf blower will fail to start if the spark plug is fouled or it has run out of fuel. Using the incorrectly mixed fuel will also prevent it from starting.
