I need to change my headlight on/off, interior dimmer switch. It's a pricey part 120.00 to 150.00 but I need to know if I have to pull the dash to change it or if I can access it from underneath the driver's side dash. This isn't the switch in the steering column it is the pullout switch in the dashboard, lower left driver's side. Any suggestions? Any previous experience changing it or anything close?

Thanks

Vince
