Check for a sweeping sound, engine off and no radio, if the key buzzer is activated close the door. Now listen while you change from defrost to floor and there should be a vacuum sound. If not run the engine for about ten seconds and shut it down and try again. If you don't hear anything. You've got to check your vacuum accumulator under the engine cover or the hood depending on how lucky you are. It's a big black ball with two vacuum lines going to and from it. Check that both are active. Also, is your blower fan changing speeds? If not look under the dash on the pass side for a four conductor connector to a plastic plate. remove the plate and you'll see three springs of different sizes these control your speeds on the blower if they are burnt then you need a new resistor plate. It may also be located under the hood against the firewall on the pass. side.

Can't direct where the air flow comes out of


More than likely a stuck gateway for the air. They are small door driven by a small amount of air pressure or a electric motor. If electric replace switch, if air more than likely a small line is leaking and not providing enough force to close door.

Cold in Michigan


check your climate control that could be the problem not opening all the way, also if not enough hot air comming out coul be the blend door some cars they used to use vacuum instead electricity to change air outlet some times these hoses get cluged theyr conected to the climate control. now try a cardboard in front of the radiator this will give you extra heat.

Chrysler cirrus, heater blows warm through dash but cold on defrost and floor


If the heater is working correctly, and the air temp does not stay the same coming from different outlets, the problem could be a blend door under the dash. The blend doors direct air thru the heater core and out the vents.

I have a 2007 dodge 2500 diesel and the heater will only heat up to a very light heat.


Mode Door 1.
a.This door regulates air flow to either the dash vents or defrost/floor. If you have air flowing only through the vents with no defrost or floor, this door is failing. From our experience, this door is usually the first domino to fail. Not sure why, just is.
<!--[if !supportLists]-->4.Mode Door 2.
a.When mode door 1 is set to divert air away from the vents and into the second stage of the system, door #2 chooses whether air goes to the defrost vents to the windshield or out through the floor vents in the passenger and driver's side footwells. Failure is indicated by an inability to choose between defrost and floor.
b.This door turns out to be the most difficult to replace. In order to replace the door, the dash panel has to be removed. It's still better than the dealer fix because you don't have to evacuate the AC system, drain the radiator, and remove the plenum box. But it is more work than the other fixes. When this door breaks, it falls in the down position, blocking the floor vents and diverting all air through the defrost vents. From a safety standpoint, this is good since you'd most likely rather have a clear windshield than warm feet. We suspect that a large percentage of customers will just leave this door unrepaired. You will have heat through the dash vents and to the windshield, just nothing to the floor. It's inconvenient, but you'll have to make the determination if warm feet are worth the extra work to fix the door. An extra pair of socks is easier.

2006 chevy silverado 2500hd truck heats up to operating temp while in parking lot blower works well but truck will not blow any hot air until truck is driving at at least 15 to 20 mph. fuses good think...


If I understand you correctly, your temp gauge shows correct operating temperature, your blower fan blows air that you can feel with your hand from the right floor or dash outlet, but that air doesn't feel warm until you are moving?

If so, several possibilities come to mind. One is that your coolant level is low. Even though your temp gauge reads in the right range, the coolant level could be low enough that it doesn't reach the heater core until there is enough engine RPM to create more pressure from the water pump and force what coolant is there toward the heater core. Another possibility is that your heater controls are not able to do their job. A stuck flapper in the duct or a malfunction with the temperature control system could be causing the problem, and at 15-20 MPH there is enough air coming through the outside air vents to provide some heat.

I'd check the coolant level first, though. The other possibilities are more far-fetched.

01 dodge 2500 v8. Air conditioner started out strong, blowing cold air..temporarily would start blowing warm and then back to ice cold...Noticed when stopping and turning corners a hissing noise coming...


Hi. Have your car aircon evaporator cleaned. Check also the drain hose. All water should go out of the car through the drain hose. There might be something clogging up the hose that is why water will run out the floor and that causes also the aircon to work intermittently.

Have a good one!

Heater doesn't work?


Your thermostat may not be working properly. Coolant flows thru your heater core where the blower motor blows that heat from the coolant thru your vents. If the coolant is not warm enough wich is a sign that your thermostat may be stuck open or opening too soo, your air may be colder than normal.

Fan forced air trouble in a 2005 Focus


it could be a vaccum line thats disconnected or the bypass vent door that diverts the air is either stuck or broken.

The fan sounds like it's blowing but little air comes out.


The A/C blender doors on the 2006 Ram are defective and are prone to breaking. Call your local dealer and ask them if they've heard of this problem. My truck had the same issue and Dodge repaired it under warranty. Good luck.

Poor air flow from floor vents or when multiple vents choosen


There has to be something blocking the output somewhere. Check where vents come out to see if something has fallen down to block them.
