Trunk Wiring Problems of Lexus ES

On the passenger side dashboard next to temperature control switch, dashboard vinyl is melting, it has bubble and one bubble was broken to make a hole. I noticed it on April 1, 2014. When I changed the cabin air filter on March,31 in glove compartment, I didn't see it. I brought my car to new country Lexus and described the issue hoping that their technician may see issue with temperature control resistance may causing wiring to heat that is causing vinyl to melt. But they didn't see it that way, instead they are saying that I might have dropped a chemical on it, I swore to them I didn't use any chemical and I don't have any passenger except my wife. I don't want to fix the vinyl until I fix what caused it. But, unfortunately Lexus dealerships trained technician didn't see anything causing it from the inside the dashboard. By taking second opinion from outside repair shop, he mentioned the temperature control resistance may be heating up the wire that might have caused the vinyl to melt. I feel that this is a real issue and it may cause a fire. I have opened a case with Lexus corporate and a case manage promised to call me by April 4, 2014. Updated 04/17/14.
