Sorry no pictures :)instructions at http://www.ehow.com/how_4520846_replace-...
Replacing the Front Heater Core
1 Turn the steering wheel so that the wheels point straight forward.
2 Disconnect the negative (black) battery cable.
3 Drain the coolant by twisting open the valve at the bottom of the radiator. Use a clean container that holds at least 10.5 quarts. You will reuse the coolant later.
4 Remove the panel on the lower left side of the steering column and disconnect the parking brake cable with a pair of pliers.
5 Unscrew the 10 bolts that connect the steering column cover liner to the instrument panel and remove the cover.
6 Turn the key to the LOCK position and turn the steering wheel to the LOCKED position.
7 Unhook the gear shift cable and remove its mounting bracket.
8 Unscrew the two screws that connect the bezel to the instrument panel and remove the retaining clips. Remove the bezel.
9 Remove the two screws that connect the steering column shroud to the column and remove the shroud.
10 Remove the coupler from the steering column and intermediate steering shaft.
11 Loosen the nuts that connect the lower steering column mounting bracket, but do not remove them. Completely remove the two nuts and washers from the upper bracket.
12 Pull out the steering column.
13 Remove the interconnect and bracket that connects the instrument panel to the chassis wiring.
14 Remove the boot from the bottom of the steering shaft.
15 Use locking pliers to pinch off the heater hoses in the engine compartment. Remove the plate covering the heater core (the hoses run through it) and disconnect the hoses.
16 Unclip the connectors that hold in the heater core. Lift the accelerator pedal to enable you to slide the heater core out part way. Press the brake pedal to make room to completely remove the heater core.
17 Replace the heater core. Installation is the reverse of removal. The nuts on the steering column mounting bracket should be torqued to 105 ft. lbs. Torque the pinch bolt on the coupler to 21 ft. lbs.
i did most of what the response said however i didnt completely remove the steering shaft simply remove the one bolt and took off the plastic cover at the base and lifted the shaft up and slid out the core whole job took me 3 hours and it was my first time doing it i also took more of the dash out then i probably needed so the job could most likely be completed in two hours
To the best of my knowledge, there are actually 3 versions of heater core used in the 2004-2007 Caravan (Caravan, Grand Caravan) and I believe the main difference is the location of the hose connections. While I did not take photos, the only steps I needed to do on mine were:
Removed center dash cover (this is the section beneath the radio. 4 or 6 easily accessible Philips head screws)
Drop the brake pedal down (very easy. Remember to remove the brake switch first)
Remove the bolt on the steering column (basically splits the column into an upper and lower half. The top half stays in place and the lower half lays down (it is hinged).
Remove the screws holding the hoses and heater core in place and slide the core out (I used some aluminum foil to catch antifreeze that dripped out while I put some plastic wrap over the hoses and hose connetions (plastic wrap held in place with rubber bands).
Reverse the steps to reinstall.

Take your time & you’ll do fine!
I was able to take the lower middle plastic section off and get the job done on an 04 Dodge caravan. The one I worked on had a tellascoping steering column with 1 screw that you pull out and the column collapsed and I was able to pull the core right out. Took 20 mins to pull out and put new one.
