My air conditioner isn't performing well and is showing these errors on the display. The windshield was replaced a few weeks ago; could the sensor be the cause? When I checked the sensor, it looked like this.

Welcome to the forum.

The two messages are simply showing the reason why Stop/Start (idle stop) is being inhibited - not for A/C errors.

You will need to get any fault codes (DTCs) read to find why your A/C is not performing correctly - it may be short of refrigerant.

Do you get any cooling at all?

Do you get the usual quantity of air-flow through the vents?

When was the cabin (pollen) filter last replaced?

I changed the sensor and all problems gone.
