04 Suburban Z71 heater fan headache

Our 04 sub Z71 with auto temp has the front heater fan on high all the time even when shut off. Also sometimes the display blanks out or the 2 temp knobs don't change the temp. O Reilly's cannot seem to find a relay anywhere on their diagram and it all worked a day ago and this morning it acted up.I know it's something simple, just would be nice to not pull fuse on shutdown and re install on startups. Ideas what to replace anyone?
