    Is this 4-port heater valve used on Limousines? If so,

    Flip it round you'll find some sort of arrow pointing in a direction that will be your inlet, The middle one goes to the inlet of the Heater Matrix and the other two go to the last two spare pipes.

    What exactly do you mean by "heater valve", and where about is it located?

My 2004 bantam pickup with the 1600 rocam engine has got a problem with the heater staying on even on cold setting.I already replaced the heater valve.Assistance would be appreciated.The heater cant be...

Check your hot and cool trim door or flap under the dashboard, the stepper motor that controls it sometimes either gets jammed or just wears out and stops working or if you won't need the heater you can put a valve in the input and output hoses to the heater core and eliminate the hot air and have it accessible whenever you need it?

Heat sometimes works in 2003 envoy

First I recommend checking that your coolant level is good. Please check this cold so you don't risk getting burned. I have seen too many heater complaints where the coolant level was simply too low to fill the heater core. Next, you should check if the heater control valve is operating. I don't have any GM experience, but heater valves are often the cause of intermittent heater operation in many cars. Good luck!

I would try back flushing the heater core, i've run into this a few times on these cars and the core was plugged, its wroth a try, all you need is a waterhose and remove the two hoses to core and flush water through both hoses until you get a clean stream of water then try the heat.

I have a 1984 cadillac deville small plastic piece inline with heater core hoses leaking back of air filter on top...what is this piece called?

probably your heater control valve. below is a replacement from autozone, but yours may look different. If it isn't the control valve, maybe it's a splice someone put in. The control valve is the only thing that comes stock in the heater hose.

89 740 volvo GL heater failure

Several suggestions:
  • Your thermostat needs replacement and your dash gauge is not reading correctly. Cheap and easy to put in a new thermostat to confirm.
  • Your heater core has a deposit of sediment or minerals restricting the flow of warm coolant in which case the system may benefit from a backflush.
  • The heater water valve has a blockage restricting flow and may be in need of replacement;
  • You have a vacuum leak which causes the heat vent control to work improperly;
  • Your firewall-side heater water valve was installed backwards; The arrow on the valve points to towards the firewall inlet, not back towards the engine.
  • Control cables from the heater control unit to air mixing doors are maladjusted or broken. In heater-only cars (no AC unit), the water valve (which is inside the cabin, above the left footwell) is controlled by a cable from the air mixing door.
  • Check the heater hoses, I have seen several 700's where they are swapped over and it results in ZERO heat. See the section on Water Valve Replacement for correct installation instructions.

1995 honda accord doesnt switch from air to heat. I have to do it by hand under the hood but cant remember where the switch is

You're referring to the heater control valve. In most cars, it is behind the engine up next to the firewall.

Has the cable from inside become disconnected? It should fit into an arm on the valve.

Replaced the heater core. now i cant get good heat

the heater control valve is likely crusted shut ...replace that and any hoses that where crimped for a long time to heater core and backflush system with heater open full...also be sure head units cables vacuum lines and electrical were not disturbed when you tore out heater core
