I have a 1985 F150. After seeing a pink nose poke out of one of my dash vents, I determined that I had wild life living in my truck. I have cleaned out the blower motor housing under the hood, the box...

If you had rats or some other type of wild life in your heating vents, it would be my guess that they dragged some nesting material like paper, rags, straw into your heating ductwork. Just a guess.

I have a '03 Dodge Grand Caravan Sport AWD that the heater only blow hot air when going down the road. Van has a new radiator and new thermostat. Sometimes the blower will not kick on for a few

If the problem is a lack of air flow from the vents, and you suspect the blower motor is not running at times, you would need to test the blower relay and blower motor for power and ground when it is not working.

check the fan relays on the sides of the radiator. Check for right amount of antifreeze in radiator. Change the Thermostat (it's a pain to remove it, so you might as well change it with a new one). The driver's side radiator cooling fan should always work, and turns on-off according to engine temp. The passenger-side radiator cooling fan ONLY comes on when the A/C is running. IF it doesn't come on when the A/C is on, check the operation of the Blower motor (blows air out of your A/C vents). IF it doesn't work, check the Blower Motor RESISTOR (mounted inside the Blower Motor housing). See picture - RESISTOR is #5.

My 2002 mercury sable heater is not blowing out hot air at all. It will run warm and then dead cold. I have chaned out my thermostat. Flushed out my heater cor with water drained my radiator cleaned my...

There is 3 actuators. One of them controls how much outside air gets mixed in with it.
The other controls how much hot/cold air is mixed, and one that directs the air. Floor to defrost. Which one was you looking at? The one that go's from floor to defrost is closest to driver side, under dash. The one that controls hot and cold is about in the center at the bottom of the ductwork. And the outside air is before the blower.

I would say that it is the mixer one. You say you can see it moving freely? I know in my truck, the stem broke loose from the flap inside the duct work. It would just blow hot air though. And lots of it. Or it would go to freezing cold. And get stuck there. Whenever I tried to turn it down a little.

Take the screws out of the bottom ductwork. That is the big vent comming from the blower over to the driver side. And check it out. Could have something stuck, Ink pen or something. And make sure actuator go's both directions and shuts off. I seen them get stuck trying to turn in one direction until it hits a switch and stops.

Good Luck.

I have a 2000 Dodge Dakota and the problem I'm having is that the A/C doesn't blow very hard at all. The blower motor is running and I can cycle it through various speeds/vent settings without issue, it...

The blower side of the a/c evaporator core in the ductwork may be partially plugged with crud that gets into the fan and ducts from the grill area ahead of the windshield. This gunk coats the evaporator core fins and prevents air from passing through it and results in a large loss of airflow. Often you can remove the blower motor and look into the ductwork and see the evaporator core. You may have to use a mirror to do so but odd are you'll see a gray coating of crud coating the aluminum core fins. I use compressed air with a long blow nozzle that I can bend as needed to get up to the core and blow off as much of the crud as possible. You never get it all off but usually can get back about 90% of your airflow. If you can't get to the evaporator core then the ductwork may need to come apart enough to clean it out. A borescope works pretty well to see up in these areas so if you have access to one of those it helps quite a bit. Good luck!

Air and heat not blowing air through vents

Either Your fan switch is burned out or you blower motor is no good, your blower motor is on the passenger side under the dash. Before you replace any parts you need to check your fuses and relays under your hood and in the car. Usually if your fan switch goes bad you will still get some air blowing thru the vents, so my guess would be blower motor, If its not a blown fuse or relay.

2001 Suzuki XL-7. Heater blows hot one side, cold the other.

No ductwork [to the lower vents] under the dash. They are part of the heater core / blower housing is integrated (all one piece).

After reviewing shop manual, we suspect that one of the three damper flaps is not positioning correctly; or debris has blocked one side (which makes more sense given the symptoms).

We're waiting for the temperatures to get back in the plus numbers to check out the physical arrangement.
