More power to you for doing the repair yourself. Even though I had the shop manual describing the repair procedure I could not summon the courage to do it myself.
I was too worried about the outside temperature display, and whether it might suffer during the bulb repair. That is known to be a very expensive replacement part.
Maybe I was too cautious, but it was a $50 job at the mechanic. If you diy, be sure to replace all of the bulbs.
