If "both" Heater Core Hoses feel the same in heat, with the engine at normal operating temperature: The Heat is regulated by the "Air Door" & the "Air Door Actuator" which allows air to flow across the Heater Core. Many times the Air Door Actuator will stop working & need to be "reset" or replaced Use of Dealer Scan Tool is needed to test prior to replacing parts apprx 1/2 hour labor Try a RESET first Ignition in ON position or engine running. Simultaneously press the A/C and recirculation buttons on control head 3 times in less than 2 seconds . The Mode setting lights will flash during calibration and will quit flashing once calibration is completed. This calibration process can take up to 30 seconds If the above does not work, you need to check the Air Door Actuator to be sure it is working Don't Forget the deposit you placed to ask this question is not used to compensate me until you rate my service!
