First, thanks for chiming in. Much appreciated.

No... When I press 'max-a/c' the blower goes to full power but the air only feels slightly colder than ambient.

My main concern is that when I press the auto button and the fan speed is set to high, even with the temp set to its lowest setting (16degC) and the cabin of the car feeling like it's over 38degC (100+F) the 'auto fan' blows minimally, as if the car thinks it's close to 16degC therefore doesn't need to work hard to lower the cabin temp.

If I then disable auto fan, I can manually increase the blower speed but like max a/c it blows air slightly colder than ambient.

The seat-blower is set to come on automatically for Temps above 25degC, however it's not coming on automatically. Again, points to a sensor issue.

All was working fine a week ago. I think she's just had enough of this brutal Houston weather!

Looks like I'll need to take her in for a diagnosis.
