Good morning this is pretty straight forward. The vent solenoid is located in the charcoal canister and has a 2 wire plug, it is held in by quarter turn lock in style, give it a twist and then pull out. The gm part number needed is 22865590 once the connector is removed take a look at the electrical terminals for corrosion. If corroded they sell a new pigtail if needed. Should take about a half hour to replace.
