..been covered before, I know. My search-fu is coming up dry this morning. HOT DAY. Need to do many short drop offs.. and need to keep the A/C running cold while away from the car. What's the trick when leaving the car to keep the A/C blowing.. as I take the fob with me. Prefer to have the car secured (locked) while away from it. Don't have a smartphone to kick A/C on using App each time. THANKS!
