How to remove and Where is it?

[Joe F]

In that order. All help gratefully accepted. I don't have a manual and I am having some difficulty understanding how to do a couple of things. I have a chilton book, but it does not address this at all as far as I can see.

First of all, the 3 button a/c switch for 1989 5251. The part number is 6131 1 391 764. I can't figure out how to remove it? There are spring tabs on the top and bottom, but I don't see how to access them from the front? Does the radio have to come out first? or is there some other way in there to compress those tabs and remove the switch?

Second, the remote temp sensor. The one that reads the outside temperature... Where is that little beauty? I have been looking for days trying to find it. Any one guide me on this quest?
Thanks in advance.
