Hi

There are definitely Uber WAV available, but also some accessible taxi services in Chicago:

• ChitownCabbie Taxi Service – All of their taxis are wheelchair accessible – https://www.chitowncabbie.com/
• Open Taxis – centralized dispatch for all Chicago wheelchair accessible vehicles – http://opentaxis.com/

All buses are wheelchair accessible too.

I may be too late to the game — sorry about that.
While the buses are (supposed to be) w/c Accessible, only some of the CTA (Chicago Transit Authority) train stations are Accessible (with elevator). Here is an inelegant and cumbersomely written list of those. 
If you already went to Chicago I hope you had a marvelous time! We are going mid-October for a long weekend. After, I’ll post all our specifics because we are going Full Tourist.
