SOURCE: heater does not blow hot air, just cool air

You can put a higher temp thermostat and that should help, but it should at least have 170 degree air right now if it was working right. There are two other things you might check for, the diverter door make some sound when you switch from heat to cool and back, I can't tell you for sure if it is a manual, vacumn or electric but that would definitely cause it to blow cold air. There is also a valve which cuts off circulation to the heater core when your not using it. This valve will be in line with the heater hoses going to your heater core. I have seen some that were actually part of the heater core box. I feel pretty sure one of these will be your problem. Also if your car is low on coolant it would not heat properly. Hope this can help you!

I had exactly the same problem. When your engine is cold and off check the gap on your ac compressor with a feeler gauge, it should be between 0.3 and 0.5mm. If it is larger you need to re-shim which invloves undoing a nut on the end off the compressor and removing the clutch plate, then removing the appropriate shims (look like washers) then replace. The reason it blows warm after 10 minutes or so is because the ac compressor gets hot and the clutch gap gets too large for the electro-magnetic clutch to engage. Some people would say that you need a new compressor but all you need to do is a re-shim.

SOURCE: 2001 s-10 heater blows cold air, then hot air,

May want to start with seeing how much coolant you have in the system. Sounds to me like you are low. Make sure to check it while its cold. Removing the rad cap while hot is a bad Idea, may get burn!

Heaters slow at warming up


In normal circumstances the heater wouldn't begin blowing warm air until the vehicle has travelled 5 miles - call it 5 minutes. That's because the thermostat only begins to open at around that mileage/time and allows coolant to circulate around the engine. Before that - there just isn't any warm coolant in the heater matrix.

After 10 miles/10 minutes of normal driving the engine will be at its correct operating temperature and the coolant will be hotter - as will the circulating coolant in the heater matrix. That's when the heater blows the hottest air.

If you're sure that the heater has lost efficiency it may be due to air being trapped in the heater matrix/coolant system, or a blockage caused by limescale/engine corrosion within the heater matrix itself.

To remove any trapped air, set the heater to maximum, remove the radiator cap/coolant bottle cap and let the engine tick over for 10 minutes.

If the heater matrix is blocked/partially blocked, drain the coolant system, refill with plain water, set the heater control to open .. and let the engine tick over for 10 minutes. Drain it again.

Refill again with plain water and add a can of 'radiator flush'. Follow the instructions on the can of 'radiator flush'.

Drain again and refill with coolant/water.

If the heater is still inefficient then the only option is to replace it - and that's not an easy job.

Long time before heater blows warm air


That seems pretty normal, the heater works by blowing excess heat from the engine coolant. So the coolant has to be warmed completely for the heat to work, you can get a heater that plugs into your cigarette lighter that will heat the vehicle instantly.

Engine heats up but takes a long time for warm air to blow. Once working, the thermostat works fine. Sometimes, warm air starts to blow and then goes cooler.


low fluid level or heater control valve may need replace..check hoses going to heater core...if cold...between heater control valve and heater core..replace control valve

2004 toyota celica will not blow hot air for twenty minutes


If the engine temprature does not reach the normal level as it used to, it may be the coolant thermostat.

Iif it does, it could be air diverter gates not working properly, cold air blowing at a a light could point to that. The diverter gates are located under the dash.

It also coul be the valuve that controls the water to the heater core, but unlikely cause of the cold air at a light.
