SOURCE: 2000 Chevy Silverado 4X4 - Heater isn't blowing hot air

No your thermostat is stuck open which will not hurt the engine. but needs to be replaced, the thermostat is what allows the engine get up to operating temp. before allowing water to flow through the radiator and when it is stuck open it doesnt allow the engine to reach operating temp. so the heater never gets hot. I hope that helps you out.

SOURCE: heater is blowing but its cold air not hot air 2000 expedition

Make sure the heater core is in the open position by using the shut off valve and turning it to open. next, you may have a malfunction in the direction door the directs the air flow in the dash. a lever may have become lose or separated. may be a bad servo motor not directing the door to move to the heater position. i would start by checking that shut off valve first on the heater core.

SOURCE: ford ka heater blows hot air all the time

Taurus does not use a heater control valve. It runs coolant thru the heater core constantly. You may have a temp blend door actuator problem or a plugged up heater core is also very common. Feel the heater hoses, they should both be very hot, it one is much cooler; you can try to back flush the core.

SOURCE: 2000 Jeep Grand Cherokee Heater is not working fan

blend door actuators. If you have the AZC system (automatic zone control) used in the limited (the one with dual digital readouts) you can use the on board diagnostic to read the code. while running, press the a/c and recirc buttons at same time then turn drivers temp control one click clockwise. release a/c and recirc buttons. If you have codes that show up, write them down and google search for these codes. It will tell you exactly what is wrong.

2000 caddy Seville ...after starting and engine warm turn on the heater and it blows cold air. Fan works / waiting for hot air and then all the sudden it kicks in. Engine at normal temp


Low coolant, if there is an air pocket in the engine it will make it to the heater core. Once there , the air coming out is cold/cool. Once the coolant fills the heater core, it gets hot. If the coolant is fine hot or cold, then have the HVAC system scanned.

Check the vacuum hoses from the switch to the engine compartment. If you manually operate the heater valve on the firewall (follow the 5/8" hose) you will get heat.

Heater not working on ford focus diezel year 2000


does your blower motor work or it just blowing cold air?
if it does not blow then check the fuse, the motor may be bad
if it blows cold air only then check your coolant level
check to see if the heater hoses are hot on both of them
if the hoses are hot then you may have a blend door actuator bad

I have a 2000 Taurus with a V-6 standard motor. Unfortunately when the heat is turned on it will blow air, but not hot air. The a/c works just fine also. Where should I start looking for the solution /...


Start by allowing the motor to run until it reaches normal temperature. Check the top and bottom hoses on the radiator, if the top is hot and the bottm is cold it's likely the thermostat is stuck closed. Also check the hoses on the heater core. If they're not both hot the heater core is blocked.

Have a 2000 ford expedition and the ac in the front blows hot but the rear ac works fine. what could it be


Listen and see if the vent flap is moving from the hot position, to the cold position. If that's working then the evaporator may be clogged. It sits inside the same box that the heater core is inside of and if it becomes clogged with hair or dust, then it wont allow the blower to blow through it. But it would then bring hot air through the vents because the heater core is there too.

No back heat in Expedition, Blows cold air but front works fine


Shelly,

Buy used parts at car-part.com. Look on page with * to find the cheapest part. Coud be your temp blend door (#2) may not be moving back and forth. Or, you are not getting hot water to the rear heater core.

3d53924.gif
You may have to crawl under the truck and feel the heater hoses to see if they are hot. You will find a group of 4 lines, 2 for heater and 2 for a/c. If hot, you know hot water is getting back to the heater core. If not, there may be a hot water vave that's not working. Not sure if EXP. has a water valve for rear.

Let us know what you you find. Good luck.
