Hello.
Remove the Driver Brake Pedal and also will help if you remove the Gas pedal.
After that youll lay on your back with flash light youll go underneeth the dash. on your left upper side youll se the blower motor.
Remove a screw top left of the blower motor.
Remove plug. ( it can be pain cuz you are upside down)
You need to twist the Blower Motor Left
This is the challenge here. After you remove the Blower motor it will not come ease. Theres is a Dashboard in your way a steering shaft. You need to find a way you remove the old (bad ) blower motor. Be creative.
After removing the blower motor(old) you need to find a way to the new one same way with you Braking the blower motor. its not easy repair.
Be patient.
Then reveres everything.
This is the way that i did it. :)
