The passenger side heat is blowing cold air.

SOURCE: heat

damper in duct to change air flow from heat to air is not working most probably. I am almost certain the navigator will have an actuator motor that has stripped, or the motor has gone bad this is constantly working when you use climate control to control air temperature.

SOURCE: Dual Temperature controls inside - 2002 lincoln ls

The problem is most likely a bad dual climate control valve. This component is located on the right side near the radiator under the hood. It will have several coolant hoses hooked to it and 2 silver cylinders protruding from it. You can clamp off the heater hoses at the heater core and see if both sides cool then and this will tell you that the valve is letting coolant thru when it shouldn't be.

This will narrow it down to either the valve or the control head inside the car,or wiring in between them. The only way to narrow it down further is if you have a scan tool that could access the climate control data. Have seen several of these valves cause this concern and have only seen one control head cause it.

SOURCE: I have a 2004 Lincoln LS and it blows cold air on

It is probably the (DCCV) Dual climate control valve. It is located RT front of engine with heater hoses and wires goin to it. I ordered one from Rockauto.com for about a $100.00 i think. It is pretty easy to change and I found out when mine went out that it was a very common problem with these cars. When mine quit it started the same as you are describing for a while then it only would blow hot air and it blew the a/c compressor fuse. The DCCV is a dual cylinder valve and i beleive that they get stuck open and short out. If you have any more questions or need more information let me know.

2003 Pontiac Montana heat gets hot in front, blows but seems weak, and no heat on rear controls but blows ******* rear. what is going on?


Is your heater blower motor working on all speeds ? Are you get any air coming from the rear vents ?

Rear blower: only works on high when set on cold, won't work at all when set to heat


I would start with the rear blower motor resistor, the resistor is what controls the speed of the fan, the resistor is located in the rear heater box near the blower, you will need to remove the right rear side panel to access the heater box. start with that

Rear heating problem


Hi Jeff. I had the same problem, along with others on my 03 Denali. Along with not blowing hot air from the rear heating system, I had hot air blowing out of the passenger side and cold air out of the drivers' side vents. My battery would go low and had the same smell. I took my Denali in to the dealer and they found it was a bad Fan Control Module. They replace it and everything worked well after. It cost me $293 for parts and labor. Hope this helps.

the water problem is a drain hose is plugged up.
should be a hose hanging down for moisture to drain out from under the evapoator. try running a small plastic tube up it and see if it will clear it.

I have a 93 Saab and my vents aren't blowing heat. When I hit a bump in the road it may kick my heat on full blast for a couple of minutes, but as soon as I hit another bump, the heat kicks off. Also, the...


You don't say whether the fan starts and shuts off with the bumps, or the heat goes cold but the fan stays on. If it's the fan shutting off and coming back, you most likely have an intermittent connection to the blower motor somewhere at the fuse box, the fan speed control switch or the fan motor, or a loose ground connection at the fan motor. The fan motor is visible under the right side speaker grille on the dash. Make sure you re-connect the short black corrugated hose to the grill vent or you won't have defrosting on that side!

The air distribution rotary switch controls where the air goes. The fan speed switch controls exactly that: fan speed. the temp rotary switch controls the coolant temp into the heater core. You need to clarify what you mean by "Also, the dash controls for the vents won't allow me to turn up the power"

You might also have one or more of the following issues:
  1. is you vacuum tank properly connected and are there no leaks in the vacuum piping? The tank is in the driver side rear wheel well below the trunk deck on a convertible, and in the passenger side front fender area on the other cars. It's a white bottle with one or two hoses connected to it. If not properly on, your vacuum operated heater flaps won't move. Does the air distribution knob make sucking or hissing noises when you set it to different positions? If not, check the tank connections, look for vacuum line leaks, then suspect the vacuum valve behind the distribution knob.
  2. if the air distribution rotary switch makes noises when you change its setting, but nothing happens, then suspect the vacuum solenoids that open and close the heater flaps - could be a loose vacuum line or a defective vacuum solenoid
  3. the shaft connecting the temp control knob to the heater valve behind it may not be properly in place. This can be inspected, and adjusted if necessary, from the left side speaker/vent cutout on top of the dash. Make sure you re-connect the black flex hose to the air vent tube, or you'll get no defrosting afterwards!
  4. remember, the centre vents always blow cold air; a brilliant idea from Saab so the driver (and passenger) can get fresh air in the face and stay awake while the rest of the driver, passenger and car is toasty!

Driver's side air blowing warm, won't change


Sounds like there is a crack in the vent that leads to the drivers side, and hot air from the engine is leaking through.

Heat when the fan blow at 2 but cold if the fan is at 3 speed


1st make sure the heated core is getting hot, do this by feeling the hoses under the hood that supply hot coolant to the core, if the inlet and outlet are hot then the core has circulation and is not the problem, check this and let me know what you find.
