I have a 2003 DTS and am wondering is there anyone who can help me. The DTS cigarette lighter circuit shuts off after 10 minutes after the key is removed. I would like to have it on constantly. I use a cell phone and other accessories which need constant power after the key is removed.

The car is equipped with a RAP (Retained Accessory Power) system. It automatically shuts off accessory power after 10 min. to prevent battery depletion in the event you leave a glove box or trunk open or a radio on. Probably the only way to have constant power would be to rewire it directly to battery power.
