Power Door locks don’t work
If you’ve got power door locks and the door locks don’t work on your 2004-05 Caravan/Voyager, or T&C van, it’s probably a software issue with the body control module. Chrysler has issued a software update to permanently solve the problem. The dealer will charge you ½ hr labor to perform the update. If you don’t want to have the update performed, you can work around the problem by disconnecting the negative battery terminal for 5 minutes. When you reconnect, the body control module (BCM) will reboot and start behaving itself. You can rest assured that the problem will return, but it may take 6 months for the problem to resurface.
If your dealer isn’t aware of the updated software, tell them to read TSB 08-040-04.

You need a professional shop manual to work on a late model vehicle. And you need access to the latest technical service bulletins so you don’t waste time and money replacing parts that may misbehave due to a manufacturer’s software glitch. Forget about those cheap manuals you find at the auto parts store. They will just lead you astray. Here are the two best online shop manuals around.
Eautorepair.net is really Mitchell On Demand with a consumer style interface.
Get a 1-Month subscription (31 Days) for $16.99, 1-Year (Best Value!) for $25.99, or a 4-Year (Best Value!) for $39.99. I like the wiring diagrams in Eautorepair.net better than the hard-to-read factory diagrams on Alldatadiy. However, Eautorepair.net doesn’t show how to remove trim or door panels. Alldata does.
AlldataDIY.com is simply Alldata with a consumer style interface. They have a different pricing model. But a 1-year subscription for $26.95. Add additional vehicles for $16.95 for a year. Or, buy their 5-year subscription for $44.95. Add additional vehicles for $29.95 for five years.
