Air Conditioner thermostat location please.

Wish I knew for sure, Bob, but I can only speak from experience from other cars I've done ac work on. Usually, the thermostat , I believe you mean the probe, is embedded in the fins of the evaporator, buried in the dash. Then, the temperature control module is a small square box about 12-16 inches away from that. I hope this helps , and wondering why no one else so far, has commented. Must be cuz it's Saturday night!!!

 

The 328's thermostat is a capillary tube type. (I found the 3ART5 one in my car on the G.E. Industrial web page -- it's from a Coke machine. I guess aircon wasn't one of Enzo's priorities.)

The thermostat itself sits in the console. An ammonia filled capillary tube runs from the thermostat up under the dash, to the front (spare tire well). Under the f/g cover is the power brakes, the windscreen washer pump, and the evaporator for the aircon (in front of the passenger). The capillary tube terminates near the expansion valve for the evaporator.

As most 3x8 owners have experienced, this is not a high precision system.

Mostly, it's to cut off the compressor when the evaporator nears the freezing point, to prevent ice accumulation from blocking airflow.

 

Yup, the thermostat is in the main console right behind the knob to adjust the AC temperature.
