I have a problem with the climate control unit on my Lexus LS400 1996 I have tried other areas of this forum but no replies to question yet. I assume that this unit does not play up too often hence no one seems to have the problem I have. The Unit is iluminated but no longer functions (blank screen only) also out is the clock and outside temp. I trust they are linked to the same problem as they stopped working together. I have just obtained another unit out of another vehicle but it is just the same.
