I noticed that BAR asked a question and I have the same problem with my Yukon Denali. It has worked perfectly fine for a year , but last week when I turned off the ignition and removed the key, the interior blower continued to run and the headlights, running lights and sidelights all remained on. The only way to turn them off was to disconnect the battery, but once reconnected and the car is used again, I have the same problem and the lights remain on. Can you help me please?
