have an interor light on a 95 C class that refuses to go out or dim. The board looks OK but the I/C on the board looks suspect. It has a number on the chip of 9321 and below that APAG AIDA 2.
This does not tie up with any component manufacturer code and I suspect it has been coded for MB.
Only the complete light is available as a spare at a cost of £150.00 which is a bit much when a £1.00 component seems at fault.
Has anyone had this problem before? des anyone now the chip ID
