Hi, When I 1st start up my 2014 wrangler the a.c. won't start operation till the rear window defroster tops blinking.
The blinking started in january ,but I wasn't using the a.c. then.
Now no a.c. till after the blinking stops for a while.
Anyone have this problem ? Thanks Biff

I had this on my 2013 jk a few starts after they changed my heater core. I took it back and they said they changed out the "control head" which I think is a computer behind the temperature gauges. Not entirely sure.

Thanks Wally !

I went out this morning looking for possible obvious loose wire exc.
I looked around & decided maybe bad connection due to moisture or fog in the damp startups ,So I rotated each end of the connetion of the wire to the window on both sides .
Well, it cleared the alarm for now ?? Thanks for the info Wally.
