Blower motor resistor

the problem is not the fan (blower motor) , it is the resistor in the blower motor hosing under the hood...
open the hood and look over by the passangers side firewall to locate the blower plenum (housing).
There is a plug that has 4 wires and it is plugged dirrectly to the housing.behind that is the resistor configuration that runs the fan at the different speeds ( more resistance = slower fan speed).
It is this part you need to replace.

A heater blower motor resistor is an electronic device with three or more progressive resistors that allow the heater blower motor to operate at slower speeds. The highest speed of the heater blower motor is not controlled by the resistor, so when the resistor fails, the fan will often work on the highest speed setting, but not the lower speeds.
To resistor is generally located under the dashboard and under the hood, near the blower motor . The resistor's electrical connector is disconnected, the resistor is removed and the new resistor is installed. On some vehicles it may be easily accessible, and on others it may take partial dashboard removal to replace the resistor.
Look under the hood, generally the wiring for the Blower resistor is attached to the wiring to the blower motor itself
It's inboard & below the motor, near the accumulator. You can see it standing beside the passenger fender. it's the off-white connector behind the L heater hose above the vacuum reservoir & the white WARNING sticker

blower motor working but not with control panel

You could just have a blown fuse but the fuse blew for a reason.
There are a few possiblities, I'll try to list them in the most likely order;
1) blower motor speed control resistors.
2) blower control switch
3) blower motor
The blower motor and speed control resistors are usually accessable from under the hood. Once you find the blower motor follow the wire that leaves the motor to where it plugs into the fire wall. This is the speed control resistor assembly. unplug the wires and remove the 2-3 screws that mount it to the fire wall. When you get it out you will find 2-4 wire coils on the back, these are the control resistors. If they are burnt or broken you need to replace them. If they look fine you need to test them with a Ohm meter or continuity tester. If they test good (having continuity) then you need to test the blower motor.
To test the blower motor, you'll need a jumper wire or an amp meter and test leads long enough to reach the battery from the plug in for the resistors. Plug the resistor assembly back into the fan plug. Fasten alligator clips to your jumer wire or use your test leads from the amp meter. Fasten your alligator clip to one end of the resistor assembly then touch the other end to the battery and listen for the blower motor to start. If it doen't start your problem is the blower motor. If it does start then your problem is most likely your fan control switch. Given the complexity of changing the switch and the many differences from vehicle to vehicle I can't tell you how to do that and I recommend you have a professional do it.

in alot of cases the blower motor resistor burns
if you follow the blower connection to left you will the resistor plugs right in to the blower but make sure you check it before you buy it take it off and inspect it you will see burns on harness and resistor
its under the passiger side dashboard you will see the blower and to the left is the resistor i think you will need a 9/32 socket or 7mm its held by one screw
good luck

the blower motor resistor is bad replace it and it will work good as new the resistor is located in the same heater box as the blower motor mounted on the outside of the heater box follow the wirring from the blower motor to find it or just simply buy the part and match it up

"...wires to fan test hot." But what is the voltage? Since the Fuse and Motor is good, and there is voltage (unk strength) to the Motor; this only leaves the Blower Motor Resistor. Does the Fan work on High Only? Then it is definitely the Blower (Fan) Motor Resistor.

three things left to check,
using test light see if you have power at motor with key and switch on,if you do replace motor,if not locate blower motor resistor it will be close to motor,check for power going in,last is the heater control assembly

it is called blower motor resistor , should be close to blower motor , you will see a plug type connector with two screws , remove the screws and there should be a resistor inside the cover for the motor, swap with new and reassemble

check the blower speed control, it most likely burned out, also jump battery power direct to the blower and see if it runs, if it does the speed control is defective, if it doesn't the blower motor is toast.
