The most likely cause would be a vacuum leak at the rear of the engine or a defective selector switch.
Either the a/c system is low on freon or the evaporator has an internal restriction....
Check the cabin filter if applicable.
Any of the following can cause this......... 1. Bad a/c - heater controller.. 2. Bad a/c - heater controller inside door operation.. 3. Bad, broken or cracked vacuum line/lines..
The flap that directs sir to the selected vents is jammed or broken...or the switch that controls it is.
Check all of your vacuum lines from the ac control panel and under your hood. You have lost vacuum somewhere witch controls your vents. There is one of them loose, disconnected or broken. Should be easy to trace. Good Luck!!
vacuum leak the vacuum reservoir is below the left head light, check the hoses
Either you need to pen your vents or there is some vent obstruction.
A plugged cabin air filter could cause poor air circulation coming out of the ac vents but you would still hear the blower motor running.
Yes it can cause bulbs to blow.
Leak in heater core. Replace core.
The Gaseous buildup inside of the internal combustion chamber would cause engine failure, the engine to blow, and explode litterally
heater on at idle and will not blow warm air. when moving it blows the warm air from the vents. what will cause this
some thing is probley cloging the vents take it appart and ckeck.
probally closed or clogged
If we are talking rain water not engine coolant I would suspect the drains under the cowl are plugged up with debris (leaves and such). If it is engine coolant then I would suspect the heater core is leaking.
Check for vacuum leak either under the hood or under the dash Check the operation of the vacuum actuators Check the selector switch Defrost is the default setting on this system
The blend door actuator may not be working.
thats because your blower went out
Hey Mike==If your car has A/C when it is exceptionally humid outside, it is common for the vents to blow some vapor. It is generally more visible when the sun is shining inside the car. Nothing wrong. GoodluckJoe
The mode door actuator has gone out. www.trailvoy.com
An Electrical Short Cut somewhere would cause it to blow the fuse. A pinch wire would ground the system, and cause a shortcut.
The HTR RR switch in a Kia Sedona determines which air vents the air is blown through from the rear heating. When it is pushed in, the lower vents blow hot air, and when it is not pushed, the roof vents blow cold air.
you need a head casket
air want blow out vents
