I have a 2007 Tucson and while rolling down the driver door window, loud clunk was heard and the window froze. After restarting the car, I was able to roll up the window. Have not tried the window since. Then I tried to unlock the door using the remote. The light on the remote came on but the car did not unlock. I changed the battery but no luck. I can still use the key to unlock the door. Now the interior lights will not come on at all.Either manually or when any door is open. Any ideas?
