A/C AND HEATER NOT WORKING

2002 Honda CRV

Air Conditioning problem
2002 Honda CRV 4 cyl Two Wheel Drive Automatic 81000 miles

Hello,
I have an 02 Honda CR-V with about 81k miles.
For 2 months now, my heater and AC have not been working. All fuses seem fine, never had a problem before. Air does not even blow out.

When I have it in outside air mode the air comes, of course, and at the correct temp I set it to, if I am making sense.

Need help before I buy parts and replace, any diagrams, info is MUCH appreciated!

Thank you!

How to Retrieve a Diagnostic Trouble Codes
The Heater Control Panel has a self-diagnosis function. To run the self-diagnosis function, do the following:
Turn the ignition switch OFF.
Turn the fan switch OFF, the temperature control dial on Max Cool and the mode control dial on Vent.
Turn the ignition switch ON (II), then press and hold the recirculation control switch. Within 10 seconds while holding the switch down, press the rear window defogger switch five times. The recirculation indicator blinks two times, then the self-diagnosis will begin. If there is any problem in the system after self-diagnosis is finished, the recirculation indicator will blink the Diagnostic Trouble Code (DTC) 7 through 13. When problems in the evaporator temperature sensor circuit are detected (codes 14 and 15), the A/C indicator will blink the DTC. If no DTC's are found, the indicator will not blink.

Canceling the Self-diagnosis Function
Turn the ignition switch OFF to cancel the self-diagnosis function. After completing repair work, run the self-diagnosis function again to make sure that there are no other malfunctions.
Max Cool Position Function
When the mode control dial is in the MAX A/C position, the heater control panel will automatically select the Recirculation mode and turn the A/C on. The recirculation switch and A/C switch are disabled and cannot be turned off in this mode. If the control panel fails to function as described, replace it.
