Question about 2001 Oldsmobile Bravada

2001 Oldsmobile Bravada no heat

2007 had heater core replaced. No heat Feb 2008. Flushed 4 x and had heat but not as hot as should be. Nov 2008 no heat again. Had it flushed last week 4x again. Drove it Wednesday. Had a little heat. Drove it yesterday, had less heat. Driving it today--no heat.

I went to GM dealer the first and second time. Not pleased with results plus it cost a lot. Went to a different repair person, he said this is a classic problem with GM vehicles.

The Bravada only has 55,000 on it. Bought it new.
I just today heard about the Dex-Cool issue-too late to become involved in class action.

What can I do?

    1998 Bravada blows cold air on heat - flush x 2 didn''t work. Saw post (automotive forums) on motor malfunction to restore vacuum and hoping that will work.

You may have an air bubble in your coolant system. If so, use a large coolant funnel designed to purge out air bubbles. The funnel attaches to your radiator with cap removed. Check it out on line. It costs about $25.

2000 oldsmobile bravada heater control valve location


If you are looking for some sort of water valve that diverts water to/from the heater core, forget it. They don't exist anymore. They went away shortly after the widely adapted use of air conditioning in today's modern cars. Now, hot coolant is routed thru the heater core at all times, but is controlled by a cable-operated, or vacuum operated "blend door" located inside the heater box. If you are not getting heat to the vehicle, there are a few possible problems:

1. Bad thermostat - thus low coolant temperature and lack of heat.
2. Clogged heater core - no water flow thru core, thus no heat.
3. Broken control head - loss of cable or vacuum actuation of blend door.
4. Broken heater box/vacuum tank - no actuation of blend door.

Of the items listed above, based on the age of the vehicle and the likelihood of occurrence, I would investigate them in the order of 2, 4, 1, 3.

The bravada heater will not heat up. it is blowing out cold air. both lines that go into the firewall are getting hot when heater is off.


The good news is that the heater valve is open and the hoses are hot. The bad news is that the heater core is clogged. If it is not even warm, it needs to be replaced. If it does get at least a little warm that means it is partially clogged and could be flushed out.

No heat at times


Check the heater core to see if it is hot on both tubes entering the firewall. If it is, then the inside should blow hot air as well. If not hot, then the heater core is plugged and will have to be flushed out or replaced.

If the heater core is hot but the inside is cool, then the blend door actuator may be bad.

Heater no heat purged system of air .flushed two times. Has heat for short time then fades out


Check heater core for 2 hot pipes. If they're hot, then the problem is in the blend door. If the 2 pipes are cool, then the heater core is plugged up and needs to be replaced rather than flushed, since flushing didn't help in the past.

Good luck on this repair.

did you burp the system after you where done. The heater d-core is the highest place in the cooling system and will be the first to collect an air pocket. Running the vehicle at idle with the cap off will help purge the air out.

The a/c will turn on any time the mode switch is on defrost. When the heat selector is turned to hot the air will first go through the a/c evaporator core and then through the heater core. When the heat selector is turned to cold air will only go through the evap core. So regardless if the a/c compressor is on or not with the heat selector on hot it should blow hot air.

Did the heat work before you replaced the other parts?

If not than it is possible that the heater core is plugged. Especially if the coolant was really dirty before you started.

New heatercore but no heat flushed system out but still no heat the dash gets hot but very little heat comes out when on for awhile the fan works just blows cold air


Did you run engine from cold, with heater on when you refilled the system? Try again, rad cap off, with heater on, and let engine get up to operating temperature, make sure you have good flow through rad ,leave cap off, until rad fan comes on to cool returning coolant to rad at least twice. Give engine a little extra rev, for 5 seconds or so, every once in a while to make sure flow getting through heater core, and add coolant as necessary. See if that helps, as it may just be an airlock in system. If your cooling system has any bleed screws incorporated, crack them once in a while as well.
