93 Fan control switch

Hey, gang, I'm a newbie to this forum. Lots of good info. I'm having to replace the fan switch on my 93 Jimmy and need to know how it's attatched to the module. I have the module away from the dash about 1/2", and I can't see a screw to take the old one off. I have the elecrtical unhooked from the switch. Anybody know where it is? I heard it takes a 9/32 to remove it.
Thanks. :grinyes:

I got it in, it was 1/4, btw. Now all I have to do is figure out the 4x4. It will be posted as a new post.
Thanks.
