One of the worst Habits of TATA (And to some extent Mahindra these days).
They have been removing pitiful small things like charging sockets, PW button back-light. Seats are made smaller in Storme compared to Old Safari (And early storme).
Rear Windshield fogging issue has resurfaced,and this time it's more severe, hampering the Rear visibility severely.
Rear defogger working all right, but I have to use it continuously. Maybe it is due to extra humidity in September with rains and all still continuing.
I am going to use the special Cream as advised by the fellow members, earlier.
Check any misalignment in boot door , whether its closing properly , also is the fogging occuring only when one of the door is opened in between the journey or once the ride is taken after it had been parked in rainy environment.
You are Bang on in your diagnosis. This is exactly what is happening!!
One thing I give you, you must be having vast experience in all this car defogger business, to suggest me solutions that accurately.
Thanks for the tip.
Now please suggest a means of bypassing it.
This was just a simple diagnosis , as in Kerala , we encounter monsoons , that's the minimum experience I have.
My suggestion , ensure that there isn't dust on the glass (both sides ) .Another thing is if at all mist starts forming , does it start from a point or does it form equally . If the case is former , then that area needs inspection (it can be as minor as a small dust particle to major issue like glass chip). Thirdly , ensure that cabin temperature is in sync with outside temperature .
