I am on the same boat, i am sure the clock spring need to be replace. Could some body tell us what is the part number for the clock spring so we can have the cruise control.

 

I ended up punching the VIN into toyodiy and found there were 2 clock springs for this model - one with a minimum number of pins, and one with all pins. I found out which was which by google image searching the part number, and found 84306-12110 was what I needed, and found it on Aliexpress.

The clock spring worked but the stalk didn't work when I plugged it in. I then found out the stalk pins were wired the wrong way around so at least that was an easy fix (pain to diagnose tho).
Result - working cruise control

 

Thanks for the reply. Now I know what and where to buy.
Where did you get the stalk? Did you also change your steering wheel with the leather and audio control?

 

I also bought the stalk from Aliexpress (searched for the part number found on toyodiy).
http://www.aliexpress.com/item/High...urn-Signal-Switch-for-Toyota-Camry-OEM-84632-34017-Free-Shipping/821036935.html was the one I bought. Only complaint with the stalk was the pins were the wrong way around.
And the little flap with a hole was purchased from the local Toyota dealer for $7.
I didn't replace the steering wheel but I wouldn't mind putting in the stereo controls one day (while trying to get the stalk working I found I could control some of the radio functions with the stalk when I wired it IP to the wrong pins. Don't ask...)

 

Thanks again for the precious info.
Few wrecker quote around $250 for the leather steering wheel including the airbag.
