1995 Dodge Intrepid engine shuts down error codes found doi

12, is for a battery disconnect, 33 is for the a/c clutch relay, and 42 is the auto shut down relay.
55 means you've ended diagnostics, and the shutdown and a/c relays are both fused, maybe a fuse is out, they are located in the power center, the PCM grounds them, I would go to this box first and test the fuses using a 12volt test light, its the best way to check if power is getting to the fuse and coming through it. You can purchase a good test light at the store and read the sections about testing the fuses. I don't know if the relays are bad but I think its best to test the power center fuses first. The black lid has each fuse and relay identifications.
