We tinted the doors and windshield . We covered the dash and used a soak rope. When we finished, the ignition would not read the key. We found that water had gotten inside a plug box on the passenger side kick panel. Opened the kick panel to access the plugs unplugged the 2 plugs and used compressed air to blow them dry . Put them back together and all worked fine. Not sure how water got down there , but it did.. Beware..
