My 2003 Yukon Denali rear air conditioning fan motor continues to run when my truck is turned off and the key is removed. It is so bad that it drains my battery all the way down overnight. I removed the fuse as it was the only way to stop it. How can this fan motor continue to run with the key out of the ignition? Thanks!
