Your 1998 Pontiac grand prix gt has some areas behind the speedometer with fading lights between 60 and 90 mph and also by your climate control can't see anything at night how do you fix this?

There are several lights behind the dashboard. When some of them burn out you will get some spots that are brighter and some that are quite dim. Replacing the dash bulbs is an annoying process. It usually involves disassembling the dashboard and usually results in rattles or squeeks.
