The one I had in my 2001 ls broke and I have no idea what the exact name of this part is to even find if you can purchase it new from a car part store or if I have to go to a junk/salvage yard to find this. Any help someone could give me would be great. If it helps to know which one I'm talking about, it's the one that controls if it's on feet/head etc...

 

This one?

I'm sure there's tons of them at a salvage yard, but you're probably going to pay at least $5 to get into those and these will be delivered to your door.

 

Thank you, that does appear to be what I needed. When I searched on ebay myself I couldn't seem to find the thing.
