Delay in HVAC buttons
I have a 2012 V6 with the manual HVAC controls. I bought this used about 8 months ago and haven't gotten around to asking this till now, but I've noticed that it takes a few minutes after I start the car before I can change settings. Hadn't noticed because in the cold months I just keep the settings the same, but now if the A/C was off when I shut the car off, I can't turn it back on for a few minutes. I can't change the vents the air comes out of during that time either. After 2 or 3 minutes everything works fine, so I'm wondering if that is normal? Does it occur with everyone else?
