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.

There is no power at the pink wire. Where do I go from here? Appreciate it.

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.
