bli22 Posted July 12, 2017 Share Posted July 12, 2017 I have three reattas and a parts car. Been around the block. I have a 1990 garnet with only 50k miles. Can't get the dash to dim when I turn on the pop up lights. It's stay at full day time brightness which makes it hard to see. Also, and maybe unrelated, the lights in the climate control module don't light up at night either. Which "brain" oversees that? Link to comment Share on other sites More sharing options...
Ronnie Posted July 12, 2017 Share Posted July 12, 2017 Welcome to the forum. The car has a photocell that sends a signal to the BCM which controls the panel lights. IT is probably the photocell that is the problem. This might help you pinpoint the problem: Instrument Panel Lights - Troubleshooting Link to comment Share on other sites More sharing options...
