98 Suburban 2WD/5.7L AC Issue - HELP

Started off with less than 6 month old AC Delco compressor stopped engaging going down the road on Saturday. Of course now won't blow cold.

In testing the situation I jumped the rear compressor switch connector on the back the compressor to the battery and great news - the compressor engaged.

But now....my AC controller on the dash has no lights when I push activate the AC or Recirculate button and those buttons do nothing.
Plus I have lost control over where the air goes to.
I made a bad situation even worse.

AC relay is brand new. AC fuses in the door panel and under the hood all good.

Did I blow the controller?
Is there a fuse somewhere that works the AC controller?

Hot in Texas so I asking for help here.
Thanks in advance.
