I live in France t there is very little cadillac escalade in our country.
So I have difficulties when the vehicle breakdowns.
Currently, there is this error displayed.
P0496 Evaporative Emission System - High Purge Flow
P0496 Pend Evaporative Emission Sustem - High Purge Flow
I wanted to ask you if this error tells you something.
Can you help me fix this anomaly.
I want to add a detail.
the "AUX" button is lit on the dashboard in front of the vehicle.
But the wind tunnel of the car and the air conditioning does not work on the rear of the vehicle.
Thank you in advance for your help.
