Seeking information about AC air flow directions

Car is done, vent temps are 40F at ambient temps of 79F… feels very comfortable now.

Using the new expansion valve (part number on the invoice that was NO CHARGE) with the number 18-2141, plus the insulation under the evaporator area has allowed the air temps to return to normal.

When I asked why it was a no charge repair, I was told “because he did not fix it properly last time”… great shop and people there with integrity.

Will start putting all the dash and interior stuff I removed for their access back on tomorrow… another day or so to get it all back in place 100%.

Just in time for our current heat wave for Thanksgiving.
