The heater blows cold air has the automatic climate control and I have replaced the climate control head in dash and the thermostat. About 6 months ago had the cooling system flushed and refilled any help on this would be appreciated and how can I get a diagram of the hole system?

Here is how to get the codes from the HVAC system.

The self-test can be initiated at any time. Normal operation of the system stops when the self-test is activated.

To enter the self-test, press the OFF and floor position buttons simultaneously and then press the AUTOMATIC button within two seconds.

The display will show a pulse tracer around the center of the display window. The test may run as long as 30 seconds . Record all DTCs displayed.

This guide can help as well.
