Just bought 2001 2wd 5.9 Durango for a great price. It has 2 issues that the PO didn't want to deal with, this is the 1st. The headlights, interior, and dash lights all intermittently blink on and off together. It starts a little while after driving. I've read a lot about this, and most posts point towards the Central Timing Module (or body Control module).

I assume I need to pull the original, look at the part number, and order a new one with the same #.

Are these module's only available as a Mopar part? Or are there aftermarket options? I'd rather get a new one instead of used.. Also, when people say that you have to get the replacement module re-programmed at the dealership, what does that mean exactly?
