Remove the battery cable cables. ( will need radio code to reset) with a ohms meter probe the switch wire and note color find the same color wire at the fuse box and probe if the meter responds the wire is ok . always check fuses with a test light they can look ok and still be open circuit.
First check the fuse,if ok. Check if you still get power to the blower motor, on the plug, if so. you need to replace the blower motor and resistor. if not check power supply to blower switch,and power after the switch, if you turn switch on and off.
Well, not exactly. The blower switch gets power from the control panel that gets power from the 25amp fuse in the fuse box. The wire from the fuse box to the control panel is black and tan, the wire from the control panel to the fan switch is yellow and brown.
First check fan fuse and relayand switch.You can change relay with another with the same part number to see if that relay is bad.Then check power to and from fan switch if switch has power coming in and not going out then your switch is bad. Replace switch.If fuse and relay are good check for power at the fan and if you have power at the fan then that means that your fan motor is bad,Replace fan motor.HOPE THIS HELPS!!!
if the fuse is ok your next step is to see if you have power at the heater fan switch,if you do then the next thing is the heater blower motor resister it is under the heater assembly,that is what gives you different speeds, the last is test for power at blower motor to see if it is faulty
2 things come to mind: can you hear the fan turning?
if not check for power at fan location. If there is power and the fan isnt spinning replace the fan. If there is no power there is a problem with the fan circuit which includes wiring fuse (you stated were ok) and Fan speed switch (might be a module)
Or there is a blockage it is possible for your heater core and evaporator to plug up with dust .
