Very possible. Your CC is vacuum operated. Start with the parking brake release diaphragm. If that's good, work your way back. If all the HVAC hoses are OK, then start looking under the hood.

Check to see if the parking brake releases when you put the car in gear. If not, pull the vacuum line and cap it with a piece of tape or plug it with a screw. Then manually release the parking brake, take it for a ride and see if the CC works. If so, the parking brake release diaphragm is the culprit.
