A very common problem with these is the heater core becoming plugged.What I have done to cure this is disconnect the heater hoses and use a garden hose to flush water through the core itself in both direction with low pressure also have used compressed air to blow air through again at low pressure. Be sure afterwards to allow all the air to bleed out from the cooling system.

How do I get heat in my 2000 oldsmobile bravada


do you have coolant flow through heater core? Does the blower motor work? If that checks out, maybe a temp door under the dash has a problem?

I have 2000 astro van and I'm not getting heat, I changed thermo stat and flushed heater core. Still no heat, whats the next step?


Feel your heater hoses. If both are hot, the core is circulating. If only one is hot-poor or no circulation of the core.
If the heater core is circulating, the temperature blend door may not be working to let blower air pass across the heater core, and into the vents. If vacuum operated, watch the vacuum valves as you move heater controls-you may spot the problem. Check that the vacuum line from the engine to the control switch is working and still connected. If not operated by vacuum, the controls may have cables to the heater case or may be electrically operated. You'll just have to scope it out. Good luck.

Both of the hoses at the heater core should be hot. If one is cold the heater core is plugged. You can think of it this way. If the thermostat was stuck closed and you checked the upper and lower radiator hoses with the engine hot the upper hose would be hot and the lower hose would be cool because there is no flow. If you check the hoses with a properly working t-stat both hoses will be hot when the t-stat is open and coolant is flowing. Let me know if you have any questions and I'll do my best to answer them.

Could the thermostat cause the heater to only blow cold air even though the motor runs normal temp on a 2003 dodge caravan


1st of all, you need to check your anti-freeze level. If its not full, the coolant cannot/will not flow throughout your heater core which the coolant flow through to heat your vehicle. If it is indeed up to the proper level? Than, yes I would look into the thremostat. It may not be opening up.

No heat


Check the heater core hoses and make sure both are getting hot. If not, the heater core is plugged up and will have to be changed.

If the fan doesn't work, you wont' get heat, as well. So, check for flow of the blower fan at the vents.

If the heater core is getting hot at both hoses, at the firewall, then I would say a blend door problem exists with one of the vacuum motors.

That will have to be examined to determine why you have no heat.

Good luck on this repair.

Heater output not warm


First check to see if the system has the proper amount of coolant in it. Sounds like the heater core is blocked. You must get circulation in order to get heat. I assume the electric fan/blower is working.

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!
