SOURCE: 2003 chevy tahoe no rear heat
I know the earlier tahoe's have two heater lines running from the engine compartment to the rear under the vechile. Those lines could be clogged or pinched shut. What you do is get two hose locking pliers. Go under your truck, they are two metal lines that turn into rubber and back into metal again farther down the line. First, checked for pinched lines. If none, find where the rubber hoses are, clamp them off, remove from metal lines and drain. Use garden hose to flush fresh water through. When water comes through at high pressure and pretty clear, it should be done. Reconnect hoses, top off radiator fluid and it should be fine.

Remove Rear Expansion Valve and Inspect. Does Valve have Metal in It? If Yes, Replace Expansion Valve. Flush Rear A/C High Side Line. Replace Expansion Valve. Remove Front Orfice Tube. Check Screen for Metal. If Yes, Replace Front Orfice Tube. Blow out Lines through Condenser. Replace Orfice Tube. Recharge A/C.

SOURCE: The rear AC/Heater blower doesnt
Hello and welcome to FixYa!
As a first course of action, I strongly suggest that you remove the positive battery connector. Let it sit for at least 5mins. then reconnect it again. This will reset the system and can get the ac/heater blower back to it's normal operation.
If the problem still persists then you can check out the fuses. You may have blown fuse that's why it doesn't work. It's common on vehicles and replacing the fuse can resolve the issue.
Hope this helps and thank you for using FixYa! Have a good one!
