Piece of cake
 

I just replaced mine 2 weeks ago. Bought the bulbs on eBay real cheap. Probably takes about 30 minutes tops. Pulling the dash plate off is real easy. Getting the control housing apart is the biggest pain but there's a YouTube video out there where a girl uses guitar picks to separate the housing, it's real helpful. You can also use thin washers as I did. I recommend replacing them all while you're in there.

Did not know you could replace just the bulbs, was looking to keep the repair cost to a minimum, thus the post!
Thanks for the info!
