If your saying the blower motor doesn't work? Check for voltage and ground at the blower motor connector with hvac on. If you have good voltage and ground with no blower action, suspect the blower motor.

You can also check applicable fuses.

The hvac has a service mode. To ewnter service mode and self diagnostics, turn key on, engine off. At the same time, press off and warm on the climate control center. Hold buttons until a segment check is displayed on the instrument panel cluster. This should take about 3 seconds. If any segments of ipc do not lite, replace display. After service is entered, all existing trouble codes will be displayed. A is for acp, check those codes. Let us know.

Just to add, the acp could be faulty? The acp is in the diagram.
