My seat heater on 99 Suburban stopped working, is there a common issue with them, ie: switch or something else?

Sometimes the heating wire element inside the seat gets damaged. They are built into the foam cushion so replacement is tedious.

Here are the diagnostics for a 1998, should be similar or the same for your 1999:
