I realized recently that most of the interiors in cars nowadays are made of plastic. With the unjustified ban on sun films in cars, it gets really heated when car is kept parked for long time. Temperature inside can go upto 60-70 degree centigrade. This surely means that some kind of vapor/smell/fumes gets released by these plastic parts. If we get into car, starts AC immediately and close all windows, those toxic elements stays inside making us dizzy.
After a lot of issues, I finally got the solution. What we have to make sure before driving is to keep all 4 doors open for 2-3 minutes. After that, close back door, turn on engine, and start blower/AC in a mode where AC near legs is running. Make sure that back side windows are partly open. This creates a circulation system where blowers throws out all heavy air out of car. Do this for full speed blower 2 mins. Drive off now and dizziness feeling will not happen.
