Service ASR, SYS, and security. HELP!
Greetings all, I'm having a few problems with my 'vette. When i crank it itll run fine till randomly the SES, SYS, service ASR, and security lights come on. It wont let me rev past 3k RPM and it intermittently shuts the throttle for a split second while driving down the road. sometimes it idles at 1200 sometimes it idles at 400, no idea why. Also, the other day when the lights came on, the AC started blowing hot, I recall seeing a thread saying that the problem could be an AC wiring harness module, but I have no idea where such module could be so that I could check it.
I ran some codes and found this:
Module 1.0: H41 H72 H74
Module 1.1: C12 (normal ive heard)
Module 1.2: Segment 1, value 2.5
Module 1.3: Segment 1, value 1
Module 1.4: Segment 1,2,4,5,6,7 all value 1 (for testing purposes im assuming)
Any help or comments would be appreciated. Thank you

would the windshield wiper motor have anything to do with ASR? i noticed that the connectors are pretty bad looking and I think that would be the result of a big black cloud i had one day while driving down the road. the wipers still work though... hmm
