Sorry no pictures Replacing the Front Heater Core in a 2006 Dodge Caravan.
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.
The window/door lock fuse is a 30 amp fuse located behind the the coin box to the upper right corner of the blue relay box, it is hidden by the air conditioning vent tubing.The fuse is not immediately visible when you remove the coin tray, but it IS in the same fuse box. The fuse will be most probably PINK.---------
Start by removing the coin tray on the left side of the steering wheel. Next remove the socket that the coin tray sits in, it should be fairly apparent how it comes out, there are just a couple screws holding it in that are visible as soon as you remove your coin tray. After you get the coin tray holder out, another couple screws become visible, remove them, along with 2 others on the left side of the steering wheel (we are removing the entire lower dash panel under the steering wheel). The top screw on the left side is hidden under a small pop-out blank cover, the lower screw you will be able to see by simply bending down under the bottom of the dash section. This whole panel should come off as soon as you have all of these screws removed. If it doesn't want to come off, you missed a screw or 2, look harder.
Once this panel is off, look at your fuse box. Now look to the right of the large group of fuses in the main panel, behind the A/C air duct. You should see 3 square fuses, 2 green and one pink. The pink fuse is in the middle between the green ones and is your power window and door lock fuse.-------------- Remove and replace this fuse with new fuse.Its easily available fuse from local auto part store.Its a 30 amp fuse.--------- But if you replace the fuse and still the problem, then its a possibility that window switch is faulty and it has to be replaced.----------- Check the fuse for 12 volt.--- This will help.Thanks.Helpmech.
It sounds like the upper steering colomn bowl is loose. The bolts come up from the bottom and hold the lower portion of the steering wheel cover to the upper. The steering shaft runs down thru the middle of both. If loose the steering wheel will rock side to side in the upper bearing race, not holding the shaft tight or straight. Its actually easier to remove the entire steering colomn, turn upside down and tighten. Remove the lower steering shaft at the firewall (mark the spline alignment). Disconnect the electrical connections at the lower colomn. Disconnect shifter (if not floor console shifter). Unbolt from dash and remove the entire colomn, with wheel attached. Flip over and chek the lower bolts for tightness. It can be done from disassembling the colomn, but its a lot of work and lots of little pieces to loose.

There is a little more to it than that, but not a tough job if you have patience. You will need to remove both 'doors' on the dash-one glovebox, one fuse access panel. on US models, you will need to remove the pass side airbag as well, then 2 bolts that hold a set of relays under the airbag, then 5 bolts that hold a support bracket (also under the pass side airbag-behind glovebox.
Then under the dash at teh outside near the doors, remove 2 sets of 10mm bolts. after than remove 2 sets of 10mm bolts near where the bottom of the dash touches the tranny tunnel. obviously all the center console needs to be removed, and the center panel of the dash, as there are several sets of screws that hold that to the back of the dash.
be patient, take lots of photos of how it goes together, and where the wiring is(was), and this is pretty easy.
Disassemble the paneling on left side ,under the steering wheel. Remove all screws and pull out the panel until you can you can reach behind it to remove the two Black Relays, on the side closest to Steering wheel. Remove the Relay covers, Clean the contacts with a 1/8 fine strip of 600 wet/dry sand paper. Only place the paper between the contacts, and pull out while holding slight pressure on the relay Armature. Turn over the sandpaper and repeat once again. Very gently press the TOP resting contact pad closer to the armature, to lessen the gap between the contact points, so the armature doesn't have to travel as far to reach the closed contact position. Repeat the above with the other2nd Relay. Replace the covers, reinstall the relays And test the Door locks prior to buttoning up the paneling. Note, a pair of long needle nosed pliers will help in removing the relays. Just Grip the relay and rock in Forward and Backward as you apply upward pressure.
