    2006 DTS Noise issue

    I have a 2006 DTS with 75,000 miles. I have a on and off again humming/pump type noise coming from the trunk area. It happens every 45 seconds to 3 minutes and lasts about 15 seconds. It appears to be coming from the rear passenger side in around the trunk area. Any ideas anyone?

    You probably wont get many responses seeing as how this is the CTS forum but I have a buddy at work who has done a good deal of engine/body work on his 06 DTS. I'll see what he has to say.

    Hello VZWTechy,

    I apologize that you are experiencing a humming noise coming from the trunk area in your DTS. I see that you are reaching out to the community to see if they have any opinions on what the sound is, but if you are interested in taking your vehicle to a dealership I would like to help. In order to assist you with this concern, I would need you to private message me your name, contact info, VIN, and dealership you would like to work with. Thanks for your time and I will look for your updates.

    I don't know if it was an option of the DTS. But would it be the self leveling compressor?
