NOTE
Although the removal procedures for the heater & A/C control panel is similar across the W-Body car line, there are big differences in the shape and size of the trim panel that must be removed to access the control panel screws. On some vehicles, the trim panel is relatively small and easily removed. On other vehicles, the trim panel goes all the way across the instrument panel and may require removal of the center console, too. The trim panels are designed to be retained with a few screws and a number of clips. Trim panels change from year to year and there have been numerous audio panel and heater & A/C control options, but with some minor variations, the following procedures should suffice for the vehicles covered here. Work slowly and carefully. The clips are typically mounted to plastic tabs and are easily broken if handled roughly.
