Tanc Crusher 04-26-2010, 05:52 PM Pretty sure it would not be a TCM issue. Sounds like either a bad door switch, bad or broken wiring from the switch to the BCM which is where I believe it goes too. I assume you mean the clock. As to clock can be bad or low batteries, corroded ground, or maybe loose hot wire. Might help to include the year, model, and engine version for better help if common for that year.
