Hi i havegot heater martix problem wwith my honda civc, the heat doesn't get any hot and there is water in the passenger

Hi, maybe you have a faulty water pump or gasket, it's better that a mechanic check it as soon it's possible.

Switch to recirc instead of fresh

Just got my 2012 CRV out of the Honda shop yesterday; it blew cold air out the vents while the engine was completely warmed up.
Honda has a service bulletin on it; the heater core must be flushed several times (there's a flush kit that Honda has provided).
After the flushing, I had all the heat I ever needed.
The REAL problem is this: Honda or the dealer can't tell what the cause of no heat. Is it corrosion/air pocket/bad anti-freeze???
Asked the dealer to inspect the bottom of the bucket when they flushed it if there is debris. "Well, the water is swirling around the bucket, so we couldn't see any debris".

If the engine is reaching normal temp, and both heater hoses are hot, you may have a problem with a blend door under the dash.

no that is a water pump or a stuck thermostat. see when you are driving the coolant is going through the system which means the faster you go the faster the water pump goes and more pressure on the thermostat. you have a stuck thermostat

The heater core can partially plug (internally) causing heat from only one side of the dash vents. You can try to flush just the heater core itself, but most of the time the heater core asy requires replacement.

sounds like you have one of two problems first check at heater core lines going into heater core see if they are hot if only one is warm then it could be the thermostat but honda's have issues with hot water valve cable jamming up this valve is located behind engine near firewall on one of the heater core hoses.

air lock in small radiator for heater

It's probably the valve in the cooling hose that lets coolant flow into your heater core. This is up against the firewall about 3/4 of the way down on the passenger side. When you switch the knob from warm to cool, you should be able to see the little "arm" on the hose move back and forth. You may need someone else to watch as you move the temperature knob back and forth.

Also, watch out for over heating (not due to the valve), because it could mean that you could need to replace your water pump and/or thermostat in the near future. If you haven't replaced your timing belt recently (or if you have) and didn't change the water pump at the same time (Honda recommended) Your water pump could be failing.

Odds are pretty good though that it's just where the cable connects to the valve. It may have rusted over time and stuck, or broke the end of the cable, or just need lubricating/bending back into place.

If this is not the case, then you may just have a clogged heater core and should have your coolant system thoroughally flushed in the near future. If none of these work, you may need to replace your heater core.

Drop me a line when you check these over and I'll see what I can come up with.
