A 1998 Oldsmobile Aurora experiencing uneven heating—half cold and half hot—could be due to several issues. Common culprits include a malfunctioning blend door actuator, which controls the mix of hot and cold air, or a faulty thermostat that may not be regulating engine temperature properly. Additionally, low coolant levels or air trapped in the cooling system can lead to inconsistent heating. It's advisable to check these components to diagnose and resolve the issue.
One of the temp blend door actuators has failed.
check your owners manual in the trouble shooting section
if youre trying to turn the heater on and cold air comes out, then its most likely the heater core
My heater doesn't go cold. But to answer your question, check the engine coolant level in the radiator. Be sure that the engine is cold before removing the radiator cap. --Ken
Yes, as long as it is the correct size battery with the correct cold cranking amps.
Because it's broken.
it's old and you need to change it.
You will have only cold air coming thru your heater ducts if your core is defective.
heater core plugged or air locked check to see if hoses going to heater core are hot
Sounds like a stuck thermostat.
Low Coolant? Bad thermostat? Heater core plugged or restricted? Heater core airbound? Heater control cable not working?
it does not have cable, it is vaccuum and acuator motor driven
