Sounds like its the blend door actuator has failed or loose or cracked vacuum line going to it. These are usually not fun to replace although I dont know about your specific model, but most that I have seen you have to remove the dash.

I've has the problem twice on a 2001 3 litre...first time needed new heater blend valve, second time cause was fallen coolant level.

The heater only blows cold air,the radiator is full,thermastat is working and the engine temp is within normal ranges.


I've had this problem. 2000 GMC uses a closed coolant system. Meaning takes and returns coolant from and to the Reserve Bottle and has little air in the engine and heater systems.
If everything appears ok but no heat. "Air Lock" is the most likely cause. (With interior heater set to full heat) Solution; 1. Make sure water pump works. 2. Drain about 1/2 engine coolant into container. 3 Remove both heater hoses from engine side and flush heater core in both directs through heater hoses with garden hose. 4. Reattach heater hoses in correct locations. 4. Refill engine with coolant. 5 Start engine and run for 2 min., use caution when topping up coolant.
6. Most 2000 GMC have twist off caps with plugs located mid way on heater hoses. with engine cold, start engine these caps may be loosened to allow trapped air to escape. Do not attempt with engine hot due to hot coolant injuries. This may take more than one attempt to remove all air from heat system. 7. Lastly most 2000 GMC water pumps have a bleeder plug,( 3/8" square driver plug) located on the water pump. With egine cold this plug should be removed to remove any air. Reinstall plug with thread sealant.
Hope this helps cheers

Remove the plug from the heater control valve to check water flow.If cabin heats up OK then the fault is electrical.If not my be airblock/leak in system.

2000 jag s-type heater blows warm-cold all positions funtion but no heat


Replace your heater control valve, its the device that channels hot water either around your engine only or when the valve opens it channels it through your cabin also..
They are quite common to fail on pre02 cars...
if all your electrics are ok, and the car is running normal temps, try feeling the pipes around the valve.. its located behind radiator left side looking down.. could even check all related fuses, just to be sure..
Good luck

A/c blow hot air 03 jag s type R


You have 2 zone temperature control control. The heater control valve has failed and is open allowing the passenger side heater core to stay hot.
It is a very common problem and expensive to repair. It tends to be an intermittent problem and sometimes will work properly.
