check and see if you get water/coolant circulates when you have the cap off (only check from cold start) the original water pump came with a plastic impeller and tends to strip on the shaft also check your thermostat before replacing water pump.

your problem is caused by the air temperature control blend door actuator motor being defective, the little motor moves the door that gives either hot air or cold air or a blend of the 2.

SOURCE: 2004 Chevy Impala no heat. Fan OK. Engine warms

Your heater core is clogged. You can fix it. Disconnect the two heater hoses and put one into a bucket. Use an air compressor to blow into the other - it'll flush the contents into the bucket. Then reverse it - put the hose you blew into, in the bucket, and blow into the one that was in the bucket. This way, whichever side of the core had the clog, you can blow it out. Reconnect the heater hoses, and then burp the system or you can end up with air bubbles in the cooling system that can cause you to overheat. Click my screenname, go to Tips and Tricks, and follow the procedure there - it'll walk you through the whole procedure step by step.

SOURCE: Heater does not come on, Radiator fluid full.

Probably air locked. check to see if one of the hoses leading into heater is hot. Other cause could be heater solenoid control valve faulty. Very unlikely that the heater matrix is blocked. Easiest way to bleed heater is to remove hose's when car is cold and GENTLY flush through with garden hose and push hoses back on when full of water, so you know you have a heater full of fluid. Hope this helps

Why would the heater, a/c not work?

Heater and a/c usually run off the same fuse, so that will be the first place to start diagnosis. If all fuses are OK, check the fan motor of the inside (evaporator) unit. This may need removal since grunge often enters the motor through the vents between the engine hood and the windshield, thus clogging the motor.
If the motor works fine, it is unlikely that both heater and a/c does not work, so determine which one is at fault. A/c not working when the fan motor is OK is usually down to lack of refrigerant in the system, needs to be topped up.
Another possibility is if you checked the heater after you have found the a/c to be not working. When humidity gets high, the a/c might have iced up, thereby clogging the heat exchanger core. In this case neither heater nor a/c will work. Let the car stand for an hour or two, or alternatively drive without the a/c on to allow the ice in the heat exchanger to melt, then try the heater.
Icing up of the core is a problem for a professional a/c technician.

No Heat, fan works engine is at temp.

Check to see if both heater hoses are hot when the engine has heated up and the heater is running.

You have 2 possibilities. One is that water valve is not opening and the heater core is cold, the second possibility is that the heater core is hot and the ductwork under the dash is not switching the flaps to give heat.

If both heater hoses are hot it means the heater core is hot and the interior ductwork is not channeling heat. You would then need to replace a movement valve or motor to switch the flaps in the ductwork.

Sometimes with the high priced options, there are self-diagnostics in the control panel of the heater. You would need someone to initiate the sequence and let the self-diagnostics pinpoint the bad part. Otherwise you need to dive under the dash and troubleshoot.

2005 Buick Terraza drivers heated seat not working. Fuse is ok on panel. passenger heated seat works fine. What could it be?

Could be break in power, ground, or heat element itself.
Look under seat and disconnect heater. Check there for power and ground with test light.
Then check continuity across the element with ohmmeter.
Bad ones are usually infinite resistance, which means an open break.

I would venture to say that if you hit the dash and the motor started running then the problem would be in the heater control assembly mounted in the dash, like bad wire to Heater switch connection. A bad connection can jenerate a lot of heat and start melting things unless you find the problem soon enough. The switch may already be damaged inspect switches and wireing for any vissible damage and replace as required. However if everything looks ok with the heater control assembly, Their are a few more things you can check to be sure of before relpacing the heater blower motor. Turn the heater controles to the high heat and fan on high as well, settings and remove the heater blower motor pig tail and check to see if power is getting to the motor,( use a 12 volt test light at the wire harness side of this connection ) also check for power going to and leaving the blower motor resistor assembly ( mounted to the side or top of the blower motor housing ). If so equipped. If you find no power getting to the motor at this point then you will half to start working your way back through the wireing towords the heater controles until you find the problem. Using your test light. Now if you did have power going to the motor then replace the motor. Good Luck From Ernie @ RedDeer, Alberta, Canada.

2000 mitsubishi mirage. cannot get no heat. changed heater core/thermostat/water pump/ heater hoses still want get hot

Is the blower fan working? If so, Is the heater control valve(valve that allows coolant to to to the heater) working? Its electronic and has been known to fail. Its located at the base of the heater hose and has a couple of wires attached to it. If that is bad, you can get one at the auto parts store, and replace it yourself. Hope this helps.

I have a mitsubishi mirage,a water has appear at

If you can see the leak and it is the hose it is an easy fix. If the leak can't be traced to the hose it is your heater core, which would need to go to a mechanic. If this has helped you, please leave me good feedback.

Car heating is broke

the heater switch on the dash activates a valve allowing hot water into the heat exchanger under the dash. I think the valve is not opening so the heat exchanger stays cold. The linkage could be faulty or the switch could be faulty.
