95 cherokee orvis edition
 

So I'm having a few issues. I had just bought it a week ago. I checked the odc codes and I have 4 that show up, 17, 13 and 33 are the main ones. The check engine light came on after driving her for a few hours and code 13 came up.
the relays are ticking and I found 3 of 4 of the big ones out of a 94, which to my understanding are the same. The dash blinks along with my door lights. My aftermarket stereo deck also blinks. And when the passenger doors are opened the relays click as well as the rear passenger door lock works till I close the passenger doors.
can anyone let me know what it is I need to check or replace?
