Moon Roof Switch replacement

I have a 2004 Envoy SLT with a retractable moon roof and retractable rear storage area roof. One by one the lamps in all the switches in the overhead console are going out along with the lamps in the switches on the steering wheel. I had tried everything I know to remove the switches for repair or replacement but cannot figure out how to remove them. Can anyone help me?

Re: Moon Roof Switch replacement

I can see where screws may have been intended to be under a plastic access panel I was able to remove, but the plastic flashing in the 2 holes indicates to me that there never were screws installed. Probably installed at coffee break time. I am the original owner so I know no one else removed them. I have tried without success to remove the other access panels.

Re: Moon Roof Switch replacement

Thank you. That worked. Now that I see what kind of tab it is, it makes sense although I don't know what the nomenclature is for that particular type of tab configuration. I was afraid I would break something if I pulled too hard. Thanks again. smile
