Battery was replaced in 6/11, so getting close to 3 years.

Checked the terminals with engine running and had 14.6v fairly steady. Checked with engine off and was 12.3v, so it looks like the battery could be the culprit.

I did disconnect the negative terminal for 20 minutes and reattached it. The fan and seats now stay on. Did that just mimic replacing the battery and if so why would that make a difference if the battery is still low?
