A/C delay when starting up?

We just recently returned from our 3600 mile sojourn to Maine and back to Memphis. I have previously direct wired my ARB fridge to the stock battery and soft wired my radar detector. On our return leg I noticed that when starting the car there was at least a 30 second delay before any a/c power (the a/c controls are dark). This is definitely new, very noticeable, and hot! After about 30 sec the power lights on the a/c are available and it kicks in. Any one else experienced this? Any correlation to an overworked stock battery powering our fridge while camping? Thanks in advance. I didn't find anything when I searched.

I'll second the blend door problem. This just happened to my 17 Limited (HVAC panel completely dark for about 45 seconds with no air movement). Check to see if one side or the other is not cooling correctly. I scanned the truck with TechStream and it pinpointed the blend door. Although I am mechanically adept, I opted to let the dealer disassemble the whole dash to replace the blend door actuator because I didn't have the time. $2300 dollars later the HVAC is functional again.
