Look in the fuse box.
Fuse Map is in the manual
Fuses are in two locations: under the hood and on a passenger side panel. Under the hood, a black box sits between the battery and air filter, to the outer side. It's rectangular. Gain access by unscrewing the star shaped thing in the center of the cover. On the passenger side, look on the center column by your lower legs, to the left. There is a panel there. Remove the cover and fuses are there too.
Your local auto parts store can sell you a small assortment of fuses for that vehicle for under $10.
Check the relays and fuses.
