I've been researching this because I figured that I can do this myself. I was able to change the passenger side one once before.
On the driver side, the battery is in the way so it is impossible to reach inside the hood to change it.
Two techniques are on the web: (1) Take out the battery and then reach into the hood (2) Remove a plastic protective cover from inside the driver-side wheel well to access the bulb.
I bought this car used and don't have the code for the radio (if I take out the battery, I will be required to enter a code once I reconnect the battery)
Any advice on how I should proceed?
