My Cherokee's have not worked since getting it. My son has the same truck,and his panel lights up as per normal,when you turn on the lightswitch. I took the dash of today,well not right off,enough to undo the 4 screws holding it in place,and slide it oiut a few inches only,to try and see the 'bulbs'. Could not see them,or where they might be hidden,so then when I went back and turned my son's truck lights on,to compare, I noticed the the light appears to be actually inside the very front black plastic strip facia,itself,and cant be got at!! Would this be right? do I now need to get another whole new complete unit,if this is the case?

or are there small bulb/s in behind,and I just need to take the unit right out,to find them......oh boy oh joy...!!
