When the engine is cold,check the coolant level.
Make sure it's on max.
A coolant system should be flush every two years.
If you did a coolant flush recently then air pocket can be the cause of the un-even heating problem.
The DIY method is to drive you car onto a ramp or a steep hill.
Iet the engine cool off and top off the coolant tank.
Set MAX heat + MAX fan
Let the engine ran for 20 minutes wih the cap off and the trap air will escape from the coolant reserve tank,
Check coolant level and top off coolant when the engine cools down.
A shop will charge $75+ for this but using an air operated excavate tool!
A car with over 90K miles may experience linkage problem to the heater control valve.
The heater control valve (near the firewall) may be stick over time.
Open the hood and move the heater to max and min. Back and forth.
Clean and lube the linkage with WD-40 to free the heater control valve.
If it's a vacuum type heater control valve then cash for leaky vac. hoses.
Move the fan switch back and forth to re-new the electrical conductors.
Pass a vacuum over the control panel to prevent dust build up behind the console.

Check the coolant level, sounds like you may be slightly low....Be sure heater is on high when filling the system....Look for any air bleeds...

Cooling system low on coolant. This causes erratic heater operation. Fill it and troubleshoot the leak.
Heater core plugged. Find this by bringing the engine up to operating temperature. With the blower on high, feel the heater hoses going into the firewall. They should both be pretty hot. One should be a little cooler - within 20 degrees of the other. If the core is plugged, the cooler one will be alot cooler than the hot one. Please note that restricted / poor coolant flow can mimick a bad heater core but is a rarity.
Blend door system malfunctioning. This can cause warm air when airflow is low but not provide warm air with higher airflow rates.

also check to see if tube that runs your climate door is not pinched or broken. the vaccum tube that runs the climate door is behind and under the battery. i had same problem a year ago and the tube was partially cut. i fixed it by cuttinga piece of aquarium tubing and spliced it back together. one other thing.....check to see if your radiator over flow cap is tight. your cap maybe bad and or cracked this would also cause the problem.
