I have a 2002 Isuzu Rodeo and the in dash clock, along with the rear wiper switch and the rear washer fluid switch don't light up even though the rear defogger switch does and all three of these switches are located right under the clock. I purchased and installed a new clock which also didn't light up when connected. Does anyone have any suggestions what my problem is or is there a bulb in that area of the dash that might be burnt out but I didn't see anything when I had the dash apart. Thanks for any help offered.
