The entire dash must be removed..glove box..passenger side air bag..and blower motor...the local garage will quote you 8 hrs of labor..around 600.00 to replace the core plus parts..the core will run about 80.00,,,,with that amount of time for a professional to do the job..you can figure a complete weekend of knuckle busting,cussing fun for the layman it is a major undertaking..and with the airbag needing to be removed and replaced i would spend the money to have it done right the first time..good luck
