So today I took my MCS into a local garage to check the A/C because it hasn't been blowing cold recently. *I have in the past month installed a Megan Racing Header, new ignition parts (plugs, wires, coil), and springs.* Ever since I had all that installed, my check engine light and ASC light have been on. Here's what the shop had to say...

"We found that the system is full but the compressor is not coming on. We checked the fuses and found that the fuse to the relay control module is blown. We replaced the fuse and checked the circuit. The draw is only 2 amps. We ran a computer scan and found codes PO031, PO037, PO340 and PO445. The codes do not have anything to do with the A/C. We could see that the systems that are effected are starting to cause other problems. More testing will be needed to be able to fix the problems. The A/C may or may not keep working."

Anyone have any ideas about what's going on with my car?? What do those codes mean? Should I take it to the dealer? Please help :impatient

Take it to the dealer but dont be surprised if they say your mods caused it and its on your nichel to fix it
