Tom,
Thanks so much for info. I don't use the cigarette lighter so I never thought to try it and see if the fuse was burnt. The owner's manual did not detail that this fuse controlled the a/c control panel. I now have A/C and here in South Louisiana, A/C is not an option but a necessity.
I just found this website when doing a Google search and I'm very impressed with the information in this site. I have a few problems with my SC400 and most of my questions are answered on the forum. I've thumbnailed this site on my favorites and when I have more time, I'll be able to gain more information about my car without having to go to the dealer and receive the runaround.
As we say downhere in Cajun Land: "Merci Beaucoup, mon ami!!!"
