Defective blower motor, blower motor resistor pack, or blower motor speed control switch.
Check at the blower motor itself. Have it turned on and tap the end of the blower motor with a hammer. I did this and found out that the blower motor was going out. The blower motor is on the top passenger side under the hood. Also check the wire connections. Make sure they are seated good. If this includes for the heater then I would say the blower motor is bad.
Start by checking the fuse. If the fuse is good, apply 12 volts directly to the blower motor. If the motor runs it is good. Check all the wiring for loose or burnt wires. If all this checks out, then the Blower Motor Resistor Pack may be defective, or the blower motor speed switch itself.Start by checking the fuse. If the fuse is good, apply 12 volts directly to the blower motor. If the motor runs it is good. Check all the wiring for loose or burnt wires.

Connect the blower motor directly to 12 volts DC. If it runs it is good.
If the blower motor randomly and intermittenly quits and does not work, chances are good the blower motor itself is faulty, if the blower motor does not work on all fan speeds from low through high, it most likely needs a blower motor resistor.
You have power but make sure that you also have a good ground and if so then you will need to check both the blower resister as well as the blower switch..........
First check the fuse to see if it is blown. If the fuse is good, then it is either the blower motor switch, blower motor Resistor Pack, or the Blower Motor itself. It can also be bad wiring. Apply 12 volts directly to the blower motor to see if it is good. If it is good and the wiring it OK, then it is the switch or resistor pack. I would bet on the Resistor Pack being the culprit. The switch rarely goes bad..
If the blower motor does not run at any speed, and you are positive the fuse is good, then it is either a defective blower motor, blower motor speed control, bad Blower Motor Resistor Pack, or loose, corroded, or disconnected wiring. I would replace the fuse even if it looks good before going any farther. Apply 12 volts directly to the motor to see if it is good.
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.
find blower motor check for voltage on one of the three pins at blower motor, if so check for good grd. most likely ur blower motor is fualty.
Resistor or blower motor power module.
The blower motor speed resistor is burned out. You can replace only the resistor but the resistor probably burned out because the blower motor is going bad. If you want to fix it for good, replace both the blower motor and blower motor speed resistor.
