Just below the heated seat switch on my '93 CS there is a small black square that my book tells me is the cabin temperature sensor. My question is what the heck is it and can I take it out. Its been making a verrrry annoying buzzing sounds for about 5 thousand miles now and won't go away. I can do a quick fix for a few minutes by hitting it but that gets old awfully fast. What, if anything can I do to it??
