850 Dash Lights not working

Hi and welcome, do you mean the warning lights or the illumination of the dash?????? Have you checked the bulbs? Jim

the illumination lights, would all the bulbs go at once.

Try replacing one bulb and if it lights the chances are that they have all gone. If they are all the same age they could all have failed within a week or so. Are you aware that that you have a panel light dimmer? make sure that its not set low/off first. Jim

I have tried the dimmer switch it is in the high position. I will try the bulbs and see if it is tehm. Thanks for your help.
