you should be able to fix it look for a can near the fuel tank that has vacuum hoses coming out of it and you should be able to just buy the bad solenoid

Your heating and air conditioning system is controlled by the Body Control Module (BCM). Any diagnosis should begin with scanning the (BCM) for trouble codes to determine the source of the problem and/or which circuits and components are involved.
If a failed mode door actuator is, in fact the problem, the instrument panel must be removed to gain access to it.

SOURCE: What does purge or vent
This is refered to the DTC EVAP Large Leak Detected - The ECM has detected a large leak in the EVAP system during a system monitor test
1. Defective, loose or missing fuel cap
2. EVAP canister broke, hose cracked or not connected
3. Purge or vent solenoid defective
4. Vacuum leak at engine
So, since you replaced the gas cap already, it sounds like checking the EVAP canister and related hoses would be the next thing to do. If there are no obvious loose or broken hoses or anything, you may have to acquire more info from a Chilton's Total Car Care or Haynes manual, or some professional-grade manual, in order to check the operation of the solenoids. Check with your local Library. Mine has online access to AllData and Mitchells, besides paper versions of Chilton's TCC you can check out. Take a thumb-drive with you, and you can save whole web pages or diagrams as needed.
A smoke machine is nice, especially if you're lazy, but hardly necessary to fix these problems most of the time. If you know where all the hoses are to check them, and how to check the solenoids, there really isn't much else left.
I hope helps (remember to rate this asnwer).
