No cold air, 2 fault codes....suggestions??

[Eurotuned_A4]

So my air blows, but I don't have any cold air. The 2 fault codes are:

• 00818- Sensor for evaporator outlet temperature (G263), Open short to plus

• 01592- Air quality Sensor (G238), electric circuit failure.

The Air quality sensor is easy to replace, but the evap temp sensor is supposed to be under the dash somewhere? Has anyone had the same codes together and recommend what to do? Also if someone has an image or diagram of where the G263 that would be great. I'm really just worried I might need to pull the dash lol. Thanks!

Looks like Ill need to check everything out. From what I have found there are sensors where the air comes out and also one on the heater core housing. Hopefully its something easy. Summer is near and I need A/C!
