Mostly controls Cruise control and the vacumm disconnect axle if so equiped. No sure what it would hurt, unless it runs bad because of a vacuum leak.

Cruise control won't work....
Your heater and A/C vent will be stuck on defrosters.
If you have the vaccuum operated valve on water lines to the heater core you won't get any heat.

But if you cant move it right now then try to clamp off the vacuum lines running to it. Your jeep will run much better with those clamped.

2010 you should be able to find that stuff at most any parts store. AZ or AA or O'reilley's or NAPA see what they have and relocate ASAP to avoid losing the functions that the vacuum canister provides.
