Regarding the A/C, I decided yesterday to check my pressures before the REAL heat gets here.
I have NEVER seen a car where you have to remove the grille to access a connector !!!
( FWIW, at 70 F I had 30-35 low and 100-180 high with fan on high, full cold on both dials and recirc engaged. )
I also noticed that the radiator fan was NOT on at all times, it came on intermittently. I had read that it is always on when the A/C is on.
