So this is problem I am having on two vehicles. First found it on my Silverado for temp/climate panel. the lights are too dim to see, they don't get any brighter when adjusting dimmer. Second vehicle is Volvo. All panels are dim, and dimmer does not do anything. This vehicle all dash lights and messages and radio is dim and not readable (luckily speed and fuel gages are manual). I think two vehicles might have different issues. Any help much appreciated.

  • Is this a new phenomenon? Have you tested the batteries and charging systems? – mike65535 Jan 24 '19 at 18:36
  • in the past both vehicles had batteries replaced. – Peter Fisher Jan 24 '19 at 20:28
  • Yes, but how long ago, and more importantly how are they now? – mike65535 Jan 24 '19 at 23:25
  • in truck 6 months ago, in volvo last week, no difference, seems battery unrelated. both batteries were changed for unrelated to dash lights reason – Peter Fisher Jan 25 '19 at 1:38
  • If the dimmer doesn't do anything, there is a chance that the dimmer has failed. – Steve Matthews Jan 25 '19 at 10:53
