1997 GMC Jimmy dash cluster light

Does anybody know how to replace the light that is behind the tachometer? I replaced one that was burned out that lit up the center of the cluster but there is another one burned out. I think it is right behind the circle part the attaches the tachometer to the cluster. I tried pulling the tachometer off but it felt like it is on there pretty good. I dont think I can get to it from the back because there is stuff in the way. I also have to replace a light on the HVAC controls. The light that lights up the LO speed and Front Windshield Defrost is burned out. Does anyone know the bulb number? Thanks for any help.
