Agree. I've never had a situation where simply turning on the defrost (red mode) for a few seconds didn't defog everything, almost instantly. My X is the fastest defog/defrost vehicle I've ever had. It gets very hot very quickly though, so you don't want to leave it on for long, but it works great!
Yes I do use the defrost but mine (fogging) tends to come back soon which leaves me to believe I have too much moisture in the car. As long as the car is completely closed, windows and all, that evaporated/defrosted moisture from the windshield is still in the car and come back to the windshield again, no?
"built in dehumidifier"? Is there really one? I thought climate controller is just blowing hot/cold air to the inside of the windshield.
That would be true if you have recirculate on. Make sure you do NOT have recirculate turned on. Recirculate (closed) retains moisture, adding to the fogging. You need fresh air in the cabin to keep things at reasonable humidity levels. This is true with all vehicles and not unique to Tesla. The only thing different with Tesla is, there is no warmup time required. You have full heating available with zero warmup time.
