A/C Cycles Off Then On w/ Remote Start

[JimmyKumbaya]

I routinely use remote start on my 22 F-150 (STX, so old-fashioned ignition key) so that the cab cools off before we get in (previously having set the blower to high before killing the ignition). With the engine already running, when I turn the key, maybe half the time the A/C continues to run and the other half the time the A/C shuts off, pauses five seconds or so, and then kicks on. In either case the A/C works fine, it's just odd that there seems to be no pattern to its behavior.

Does anyone know what causes this?

Thanks,
Jim

On your sync screen you can set up remote start so that it goes to the controls you preset, or it has an automatic mode based on what the environments are. Maybe yours is in auto and sometimes that matches your presets and sometimes doesn’t????

Thanks, but no, that's not it: I've got it set to the equivalent of "use last settings." I should've been more careful in my description: having started remotely, when I get in the A/C is running at its last setting, properly cooling, with no LEDs lit on the A/C controls; turning the key cuts the A/C off for about five seconds, then it comes back on at the same setting with the LEDs lit properly (and the USB port powering my dashcam [the port at the back of the console] turns on at the same time).

Not a big deal, more a curiosity than anything else; it's just the randomness of the situation: about half the time the system behaves as described, and other times the A/C (and LEDs) stay on when turning the key.
