Welcome to the forum!
For future posts, please post the year of your car and the engine.
I see from your profile that you have a 2000 LS, so I'll assume that is the subject vehicle.
Have you tried anything to diagnose the no heat condition, such as verifying the coolant level is good and checking the inlet and outlet hoses for the heater core? Does the blower motor run?
Your dual zone electronic climate control system has the ability to run a self test and will let you know if there are any concerns with the control portion of the climate control system. Try searching the forum (upper right of the LS forum main page) for the self test procedure. I know it's been posted before. If you have difficulty finding it, reply here and I'll repost from the service manual.
