Q: Ventilation system seems to have some issues
Hey there. As you probably can see I have a 2003 Grand Marquis. Currently the air is working, however, the air is only coming out of the defrost front ventilation fans and the floor fans. On top of this, the a/c is currently not functional and I have double checked coolant levels to insure that's not the issue. I would like some guidance as to what may cause this or what might be the root cause of the error. Any guidance would be greatly appreciated.
Thank you,
Nathaniel
