Temperature blending doors might need a reset. Find the fuse and pull it for a few minutes. If that doesn't work you may need to replace the blend door actuator. Or your cooling system may be clogged.

There is a blower motor control processor for the back blower - it takes input from the front control and the rear control and decides the fan speed. That processor could be faulty, or the blower motor, or a 30amp fuse in the engine compartment.
In the front system you have a controller and blend doors that direct air thru the heater core and evaporator. You would need to check the operation of those blend doors.

Front heat does not work, rear heat does?

I'm just a regular diy'er, no training. Had same problem, 2001 Suburban, front blew cool air when heating, rear heat warmed up nicely. After reading other posts on other boards, took off the the heater hose clamps (make sure you remember which is which) at the firewall. With low pressure garden hose flushed left inlet/outlet first till I got good flow, then the right side, and back to left. Reattached hoses, started and tested. Heat blows just fine. I can't think of anything that could be damaged by this, but check with someone who know something first before trying it on your vehicle, but it worked for me. So far so good.

No rear heat

There is a seperate heater core for the back of the Suburban. It is located behind the right rear interior quarter panel. You have to pull everything back there the heck apart to get to it. The blower motor is located in the same area, so if you should be having any issues with it, plan on doing them both at the same time. Also, you have to drain the whole coolant system, so if you need to do anything with the front heater core (doesn't sound like you do), plan on doing that at the same time too. Good luck!

Inspect Brakes and Traction Control Evaporative Emissions System (E) Inspect all the fuel and vapor lines and the hoses for proper hook-up, routing and condition. Ensure that the purge valve works properly, if equipped. Replace the components as needed. Exhaust Gas Recirculation (E) Fluid - Differential Inspect front/rear axle fluid level and add fluid as needed. Check constant velocity joints and axle seals for leaking. Lubricate Steering and Suspension Lubricate the front suspension, ball joints, steering linkage, transmission shift linkage, transfer case shift linkage, parking brake cable guides, and brake front axle. Ball joints should not be lubricated unless their temperature is -12 degrees C (10 degrees F) or higher or they could be damaged. Replace Air Filter Element (E) Engine Oil (E) Change engine oil and filter as indicated by the GM Oil Life System (or every 12 months, whatever occurs first). Reset the indicator. Never drive the vehicle more than 16 000 km (10,000 miles) without and oil and filter change. The system will not detect dust in the oil. If the vehicle is driven in a dusty area, be sure to change the oil every 5 000 km (3,000 miles) or sooner. Fuel Filter (E) Oil Filter, Engine Rotate Tires
