I did some digging online and the turn signal cancel cam on this model is attached to the back side of the airbag clockspring. I thought mine was probably broken. I was right.
Here is the busted part. That little brown thing with the horns is supposed to be permanently attached to the black thing. It's not.
This is actually my second one of these to replace. The first one was in an older Grand Caravan. It had failed internally and made the airbag warning light come on. The first part I got from the dealer for just under a hundred bucks. The second one I ordered from RockAuto for half the price.
10mm Ratchet and Socket - For removing the Battery Negative cable and the airbag.
13/16 Deep Socket and Ratchet - For removing the big nut that holds the steering wheel on.
Steering Wheel Puller - Loan-a-Tool from O'Reilly Auto Parts, P/n 67011. This is free to rent, but requires a $60 deposit.
1/2" Wrench - For turning the steering wheel puller
#2 Phillips screwdriver with a 5" long blade - For removing the steering column cover. A removable-bit screwdriver would not work for me on this, as there wasn't enough clearance around the screw.
Small flat bladed screwdriver - For releasing the small electrical connector.
This chap's video on YouTube gets it 99% right.
My model is several years newer, so there are some differences.
First, you have to point the wheels straight ahead before disassembly. This is important.
Second, my airbag connectors had little tabs on the side that had to be squeezed to remove them.
Third, I had a third small electrical connector on the clockspring that could not be released by hand. I had to use a small screwdriver to push down the locking tab before it would pop off.
Next, my clockspring was held in place by two Phillips head screws instead of plastic pins.
Finally, my new part had a locking tab that kept it from rotating during installation. I left this in place until the steering wheel was in place This insures that the clockspring won't over-travel and fail. Once the wheel was on the locking tab pulled right off.
The turn signal cancels now and wife is happy. :D
