I have a 07 that I bought last August and when I went to change it it didn't have one at all so I assuming it never came with one. Also I heard from other people they there Compasses never came with one, too much money for Jeep to give us one.
I check Autozone, Walmart or another car parts store, cheaper.
I get mine from RockAuto.com, cheapest parts, many different brands and super fast shipping.
I dont go to a dealer unless completely nessesary.
