Those arent your codes I sent you a PM on how to check them

 

Thanks

 

I can tell you already what those codes are... the first one is the heating, ventilation, and air conditioning, the A0 LDCM codes are in the left door control module. the A1 RDCM are in the right door control module. I've encountered them before on my mom's vette... not sure what they are exactly, I deleted them, and they didn't reappear. I imagine it's not a problem, most likely an isolated incident. My guess would be that if you went and looked them up, they would be associated with a voltage problem.
