Default NO COLD AIR and PEGGED oil pressure

Yesterday went to work then took a 20 minute drive and came back to work in the morning, had the A/C on and worked like normal also oil pressure was normal. Got off at work at 5 started the car and oil pressure pegged even without the car started and the key on was still pegged. The A/C blew air but not anywhere close to cold like earlier that day. Pulled into my driveway and a relay was humming underneath the passenger dash (Courtesy Lights) along with the Security light flashing. So I pulled the relay and it just quit humming. So I don't know. I checked fuses and they were good.
