Word for word, having the exact same problem. I replaced the ect sensor and after unplugging the battery to reset the engine light everything went back to normal for a day. Ac back, temp gauge read the temp. Then after a day, light came on again, ac not cold, temp read 100 (needle does not move). Same code as before read at autozone. The only thing I haven't done it change the therm but if the therm was bad then when the gauge does decide to work it would be reporting irregular temp changes. Unplugged the battery again and reset the engine light. All is back to normal again gauge and ac working. We will see how long it lasts. Could it be the wire connection to the ect sensor?
