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.

check the resistors located under the hood, passenger side in the air box. two screws hold it in place as well as a wire harness to un-plug. common problem on gm and chrysler.
If thats not broke and rusted, then check the motor, fuse, and the relay.

start by check all fuses, then check for power at rear blower.if fuses are good and you have power then may have bad blower,if no power and fuses are good then may have bad resistor. hope this helps good luck.

Testimonial: "Thanks for your advise."
It is most likely not the blower motor. Intermittent operation usually means the blower relay is failing. It should be under the hood in the main fuse box. Try that before you spend a ton of money on bigger parts. Hope this helps. Good luck.
