@radwanyounes you are not telling us if at least the blower motor comes on and if you have checked anything. Things like the fuse etc. It is easily possible that this is a blower motor issue (blower motor relay), possibly related to the rear resistor or HVAC control module. We would need to know the exact year and exact model for your Trailblazer. Here is the schematic for your AC which we may need to refer to as we try and get you cooled down ;-)
