Battery Change
2003 Silverado - I just found out about re-calibrating the ambient atmo temp. sensor after changing the battery (which fix my problem). Is there a list of ALL the things that need to be re-calibrated / reset after a new battery change?
Thanks in advance.

Not that I am aware of. Good work finding out about recalibrating your atmo temp sensor, BTW!

How long did you have the battery unhooked? Most of the modules are able to retain adaptive memory/calibrations for at least 10-15 minutes with the battery unhooked.
Additionally, the systems that require calibration are capable of “learning on the fly.” Power windows, for example, will re-learn the auto function once the buttons have been used. HVAC will self calibrate if you turn the key on, engine off for about 1 minute. The PCM will re-learn drive ability values automatically, though a few odd “behaviors,” so to speak, may be noticed for the first few drives.
