Is there such a thing on a '92 Sambar? I don't see a way to adjust the panel light brightness but some stuff I came across in the factory service manual (Danko) suggested there should be. Perhaps it is only on certain models ...
Neither my 91 Minicab or my 92 hijet has them either....so more than likely the fact they were built as basic work vehicles means that dimmers were only for the luxury van versions and maybe the higher priced forced induction models...your manual prob. covers the van as well
