tdabel_GS430

Good day all, I just drove my 2001 GS430 (has Nav package) and went to turn the AC on (Climate button) nothing happen. Check the other panel buttons (Audio, Display etc.) and nothing. I tried to search for a similar problem with a GS430 here and found nothing. Can someone lead me to which the problem may be. Thanks The Silver Streak.

Good day all. I will be taken delivery of my GS430 next week and I would like to hear opinions about the best brand (i.e. Shell, Exxon, etc.) of premium to burn. By the way I reside on the East cost and will travel as north as Toronto, Canada and as far south as Orlando, FL.
