ha... $11.00 per bulb? That's ridiculous just as most other dealer requests are. I can almost guarantee that the junk yard checkout dude would just tell me to pass on through if I showed him a few bulbs. I inspected the bulbs that weren't lit, and thought they looked ok. There was a nice brown burnt ring on the plastic holder, but it was like that on all of them. I didn't see a blown filament. I did see a little bit of corrosion. Is the light circuit one of those like old christmas tree light sets where if one isn't connected, the whole strand won't glow. After messing with the blown ones, none of them glow. I don't think the one's I've tried to replace are 100% in. do it if you like. It's not a big deal to switch the blue and red buttons. They actually interchange. I dont' understand why ford would use different slides for some of the buttons, but whatever. I can switch my philosophy from colder/hotter to +/-. It's not gonna be a big deal. Then again, I'll probably have to take it apart somewhere down the line and I coudl switch it back. I'll do that. thanks for all the help. I sent $30 to the shoforum for people like you that are out there. Thanks again.
