Climate control issue

Hello All
I have an analog climate control , not the digital climate control.
The mode switches and the recirculator switch are not working , the fan control and the temperature control work well.
I already switch to a new anlog climate control and still the same issue. Ibelieve there may be a fuse or relay somewhere that needs to be replace.
Can anyone help me diagnose this problem? what can i check to try to resolve this issue?

Thanks…
