The A/C and blower work fine but there is no temperature display for both sides and none of LEDs in the buttons or dials work. Which fuse feeds the display in the control unit? Also noticed the Homelink doesn't work either when I press a button.

Sounds like you need to download a WD and look specifically for a fuse common to the climate panel and Homelink.
My mistake was checking Homelink during the day. At night I could see the red LED much better so that's fine. Do have Elsawin and the fuses for the Climatronic are good. Will have to check at the connector for power next.

Don't forget to check ground continuity as well.
