I just replaced the factory battery in my 2016 JKU. Since then, the A/C controller is flashing and delays coming on for about 20-30 seconds. I have read this means the memory in the controller unit is bad. Also, after turning off the engine and taking the key out of the ignition, the interior lights and radio stays on seconds longer than it used to.

Should I try resetting the ECU or do I really have coincidental issues?
