Intermittently, however, more frequently recently, when I tilt the steering wheel of my 2001 Dodge Durango I will lose the radio and turn signals. I believe there is what's called a multifunction switch inside the steering column. Could this be the culprit? And if so, is it a do-it-yourself fix?

Re: Intermittent multifunction switch problem?
Most definitely is the problem and yes you can do the job the cover around the steering wheel will have to come off a philips screw driver will be needed before taking out get the new switch first so you can see how it is mounted.please rank this answer thanks.

The most likely cause is the multifunction switch located on the steering colomn. Also involved in the turn signal operation is the BCM (body control module) and the IPC (intelligent power module). For the problem you are describing I would go with the multifunction switch as the most likely culprit.
The horn has power all of the time but does not go off untill it is grounded. The switch in the steering wheel is the ground when you press it completing the circuit and sounding the horn. The alarm does not use the steering column or steering wheel ground path to "beep" the horn, it uses its own ground. The problem then will more than likely be in the steering column, steering wheel switches, or clock-spring. The clock spring is not for the clock. It is a spiral-wound wire set that allows the steering wheel to turn and not bind up the wires going into the steering wheel. It is called a clock-spring due to the "spiral" wound design of the connector. The horn ground wire in the steering wheel gets its connection through this clock-spring, so it may the source of your problem. It would require some electrical diagnostics to verify the actual point of failure.
I have the same problem with my 2001 Durango. It has something to do with the ignition cylinder not making a good connection. I have to tilt the steering wheel all the way up and then giggle the key to make the turn signals and radio come back on. It's also a lot worse in cold weather.
I took the ignition cylinder out and cleaned it and it has helped the problem a little bit.
Verify that the multifunction turn signal lever is in the center of the OFF position.
Disconnect the negative battery cable.
Disable the SIR (air bag) system. Refer to the Chassis Electrical Section.
Remove the air bag module from the steering wheel.
Remove the steering wheel.
Remove the upper and lower steering wheel trim covers using the following procedure.
Remove the tilt lever assembly.
Remove the two pan head tapping screws from the lower shroud.
Unlock the upper and lower shroud.
Remove the two Torx® head screws from the upper shroud.
Remove the upper shroud.
Remove the wire harness straps from the wire harness assembly and detach the wiring harness connectors from the switch side connectors.
Remove the two multifunction turn signal switch screws and remove the multifunction switch assembly from the vehicle.
Install the multifunction switch to the steering column. Use a small flat-blade prytool to compress the electrical contact and move the multifunction turn signal switch into position. Verify that the electrical contact rests on the canceling cam. Install the screws and tighten to 62 inch lbs. (7 Nm).
Route the wire harness along the steering column jacket assembly and secure into the wire harness strap. Install a new wire tie to the upper tilt head assembly and another lower along the wiring harness, as the original installation.
Verify that the lever is in the center of the OFF position.
Install the upper and lower steering column shrouds.
Route the SIR connector through the steering wheel, align the scribe mark on the steering wheel made at removal, with the slash mark on the steering shaft and install the steering wheel. Install the steering shaft nut and torque to 30 ft. lbs. (41 Nm).
Install the horn contact leads and the air bag connector to the back of the air bag. Make sure the CPA wedge is in place to secure the connector. Install the air bag by gently pushing on both the right and left sides of the air bag until the retaining springs engage.
Enable the SIR system by connecting the yellow 2-way connector at the base of the steering column and installing the air bag fuse.
Connect the negative battery cable. Test the horn, turn signals and headlight operation.
dash is ismply snapped into place. There are only plugs in teh dash if your model is a 4wd. It's easiest to tilt the steering wheel all the eay down for removal of the dash bezel. Once the bezel is removed there are only two screws holding in the factory radio.
You've got to be very well versed in steering assemblies before attempting to do this. There are very strong springs int there and if not carefully positioned they can hurt you severely. You must first remove the wheel with a steering puller set. Make sure that the wheel is in the upper most position, first. then pull the wheel. keep track of the order in which the parts come out.Taking pix along the way often lend to ease the reassembly. Use the circlip removal tool to remove the clip holding the lock plate down.By now you'll be able to see the turn signal switch. remove the lever hold down screw and slide the turn lever out.Remove the three retaining screws for the switch and pull it straight towards you enough to lay it to the side. No need to diconnect the wires.Once you've finished with this, take the tilt pin remover from the set and while keeping a slihght pressure on the respective side, 9:00 for the left pin, 3:00 for the right. Remove the pins and then you'll be able to slide the collar up and away enough to get at the tilt lever. That's all. Reverse the order for assembly. Thanks, Dana
