2005 Sienna AC Evaporator Temperature Sensor

Hey guys, first time question. I took my 2005 Toyota Sienna into the local trusted mechanic and got a high quote to fix my ac. They determined that the evaporator temperature sensor is faulty and said that the only way to get to it is to remove the dash. Anyone out there that can point me in the right direction to where this part is located? I am going to do the work myself, and want to remove as few parts as possible to do it.

When it happens, how long does it stay warm for? My AC will slightly warm up every so often, especially noticeable when it’s really hot and humid out, but it only lasts a minute or two and then is right back to ice cold. I think this is normal and part of a “defrost” cycle to keep the AC from icing up.
