A/C Temp Sensor out?

[mfm028]

Hi all. Long time reader, first time poster.

So I've discovered that my A/C hasn't been working too well since the heat kicked in this summer. I opened up the maintenance manual and ran some of the tests. Here's what I found... when I run the fan tests (starts w/ 51 on LED screen), I take temperatures at the vent and find that with full cold I'm getting air at around 34 degrees (car sitting at around 75 degrees outside temp), but when I run the a/c normally the temp at my vent is around 55-60. So the best I can figure is that there is something wrong with a temperature sensor, so it's essentially telling the system not to cool down the car more because it's already at temp. What do you think? Any help would be great.

Welcome to NICO!!!

Just wanted to double check if they're is an obstruction blocking the in cabin temperature sensor (i.e. aftermarket dash kit? Is it clean?).

Nope, everything is original, no obstructions.
