SOURCE: 98 Olds LLC - AC works but fan air does not blow

If you have a late model GM car and the system is controlled electronically the blend door actuator becomes weak. When this situation occurs it will not move the air direction door inside of the heater/air conditioner plenum. in your case not to the vents Replace the actuator with new and recheck the system. i hope this helps

2002 ford explorer AC and heat blowing in dash, but very weak from the vents


On the motorcraft parts web site, you can blow up
a picture of the HVAC Blend Door Motors & locations,
as well as part numbers

You can get failed motor from Amazon

With knowing where the motors are located, try switching
the air flow modes manually, to see what positions do not work

Then you know what motors to replace

I also have professional scan tool software & can see the codes
for the motors in enhanced data.

The-- Vent Blend Doors-by name

Defrost-up top
Cabin -the vents as you say in the middle & on the sides
Floor
Recirculate-under the glove box
Blend Door -under the dash on your print

No heat just cold air


Is the gauge showing the engine is warming up to normal temp ?
Are the heater hoses getting hot ?
If the heater core is getting hot, it could be a blend door problem. The blend doors direct air thru the heater core and the ac evaporator among other things.

AC unit is blowing both cold and warm mixing as if


Sounds to me like you've got a stuck door. One of the doors in the air ducts isn't closing/opening all the way. Possibly stuck or possibly a vacuum leak or disconnected/broken vacuum hose. Only way to know is to pull the dash apart. Sucks but gotta be done.

91 ciera only does defrost, no vents or AC


i believe this is a vacuum operated system. if there is a problem with the vacuum supply to the control unit, it will automatically default to defrost. i would start by checking the vacuum source lines. good luck!

AC/Heat/Defrost inoperable


Chanses are its either the blend door motor quit working or the controls ( temp., selector, blower) in dash are bad, my 95 did the same thing i chg. the blend door motor thinking it was that, but it turned out to be the controls in the dash, 5 minutes work and 140.00 later it was fixed.

4.6 liter has one heater hose warmer than the other. may be plugged core,or is ther a fuse to climate control switch?


Look for a heater valve on one of the hoses if there is no valve i would say its a plugged heater core.
