Question about 2004 Oldsmobile Bravada

1 Answer

1999 Olds Bravada - High Heat is always on.

The heater is always on and on very hot. The climate/temp control has no effect on the air. If I by-pass the heater completely I can get AC. I was thinking maybe it's the blend door control but I don't know the car that well. Please Help.

    I am having similar problem with a 1999 bravada. My battery failed a couple of weeks ago and I recharged it. Ever since I get high heat - even with the system off.

I have narrowed the problem to a non-functioning climate control acctuator (a mechanical vent door opening/closing unit that mixes warm and cold air) Unfortunately it is located high in the dash and requires entire removal of dash panel. Shop repair manual states a repair time of 5.2 hours... GM parts $260 actuator $75 door panel......Online parts $60 to $175

NO HEAT. A/C works fine. Air blows but no warmth. blows cold air for front defog and cold air blows when temp cranked high 1-5


warmth comes from the heater in the car
if it is climate control check the climate control module
check for heater control in the vent settings as the hot water tap may not be turning on

I have a 1998 Oldsmobile Bravada with automatic climate control that blows cold air in the winter and hot in the summer. The thermostat is working fine and it doesn't need flushed. There are no le


It sounds like the system is fried. Based on the description, it is just pulling in the outside air and not doing anything to heat or cool the flow. Unfortunately, this is a job for your preferred mechanic.

Low heat from heater


Had same problem. Take off both hoses to the heater core at the fire wall. Using a garden hose with nozel flush with water on the "inlet hose" first(the one hot to touch) then flush the other side. A nasty blackish slim will come out. Oh, cover your distributor with a plastic bag first so it won't get wet. Put the hoses back on, set heat for full high and enjoy your nice warm bravada again!

No heat to passenger area


Had a friend with a simular problem, and as it turned out for him was he had climate control heating which means drivers side climate could be set at 72 degrees and passenger side set at 72 degrees or what ever desired temp, when selecting the temp for the passenger side it would always be cold,
as he found out when operating the heater controls the littles doors the direct the airflow were stripped out under the dash, he took it to a dealership and they were able to oder the peices to fix the pivots for the doors.
