A faulty Heater blower resistor on 1997 Hyundai Elantra

Is it difficult to change the Heater blower resistor I brought to the shop but im afraid they will charge to much but i do not have a voltage meter. Do you have to rip out the entire dash or anything? I find the part new for 54 bucks so i would hate to pay over 200

it is a simple repair. it is under the right side of the dash behind the glove box door. removing the door is easy and then you can acess the resistor.
take your time and be patient.
