I changed the vent solenoid, and erased the code and it reappeared within minutes. What could be the problem? Thanks

Good morning,
I would go to the solenoid and test for power with the key on to the pink wire. If it does not have power, it cannot work.

Check the fuse I circled in the one diagram I sent you.
If there is power at the fuse, you have a wiring issue from the fuse to the solenoid.
