I have a 2000 dodge caravan and the rear heat works great but the front heat blows cold?

The blower motors all work fine, has new water pump and brand new coolant. The top vents in the dash blow lukewarm warm but if you switch it to defrost it comes out ice cold but the rear heat still blows super hot air. Coolant level is full.
I've read about the blend door could that be the issue? Could a coolant line to the front dash be clogged? I'm a ford mechanic but kinda stumped and have never worked on a dodge.

Added (1). When the car first starts up it stars shaking and the engine kept raving slightly by itself, but after a while it stops and runs normal? Look at the video below:

Truck owners, Ford, Chevy or Dodge?

I'm looking to get a truck within the next year or two. It doesn't need to be brand new, and I'm not using it for major hauling, but for full bed use and possibly a cart extension of some sort.

which is the best truck out there for regular civilian transportation, nothing commercial related?

Vote: which car is best and has most features standard?

This vote is ignoring the price.
