HVAC control panel not working

92 Sierra 1500 WT. HVAC control panel dark and not functioning. Will not turn on AC, fan, etc... Checked HVAC fuse, it's OK. Looked for HVAC relay under hood, could not find it. Suggestions?

All of those fuses are tired together. At least that was my experience. Try looking them all over.

On another site I found a similar post and the fix is very simple. Disconnect the battery for a couple of minutes! That fixed my problem.
