Default Need help with '01 codes

I was checking my DIC codes and saw these listed:
10-PCM 1637-H and 1638-H
HVAC B0361-H and B0441-C & H
A6 SCM 2860-H and 2605-H
BO-RFA U1000-H and U1064-H


I can see I have some work to do but can't seem to find out what the PCM codes are telling me. I've checked the web page for C5 codes at stengel.net but didn't see my PCM codes listed?? Also, I know that my HVAC codes are telling me about the driver's side air duct issue (I think) that I'll need to get cracking on as well. I'd love to get these taken care of and there is SO MUCH knowledge here that I know you guys will know so, can you guys help steer me in the right direction to get these fixed and cleared?? I sure would appreciate it! Thanks!!

P1637 and P1638 are charging system codes. You have them listed as history codes. Clear the codes. Drive the car and recheck.

Thank you for this! I've noticed that I got a charging system fault message when I first cranked the car (until I cleared the codes) as well as a "service vehicle soon" message that keeps coming back. Not sure what is causing that one. I've just recently bought this car and have been offshore for three weeks so I had no real time to play with it. I've just gotten back home for three weeks and would like to fix these issues. I appreciate the help.

The HVAC codes are likely to come back (IMHO) and if you read the following thread you will have a starting place for resolving those:

I did this and, so far, no more HVAC codes......so far. I did notice however that the PCM code 1637 came back and showed both current and history.... I hope that doesn't wind up being something costly. I did see where it is for the "Generator-L circuit", whatever that is. I have lots of research left to do... Also, I'll keep checking back here to see what advice others have to give as well.

Again, THANK YOU!!
