SOURCE: a/c problem

You either have a bad control, or motor running the air direction door in the front HVAC unit, or a door that is stuck.

The front and rear units are totally separate.

The door directs where the air, cold or hot, should come out, whether it is panel vents, floor, defrost, or any combination of those.

This door and motor are located inside the heater box which usually requires a lot of the vehicle dash assembly to be taken apart to get to these parts.

SOURCE: Heat wont blow through heater or defroster vents

The door in the heater box is most likely stuck. It is located under the dash on the passenger side

SOURCE: astro van 1997

There is a flap in your heater box that is controled by your vent switch by your heater controls. listen for a vacuum leak. that is common and hopfully the problem. there is vacuum lines that control the vent door that redirects the air to your vents.

Has your dash been messed with recently? if so i would check there first. you should hear a hissing if thats the problem.

Otherwise these also are common for that door flap to break and not switch NE more. thats the only 2 things that i can think of off th wtop of my head to be the problem. this would require the whole dash to come apart if its this problem

SOURCE: when i have the heater/defroster on the heater

It sounds like you have a blend air door stuck. This is in the housing of the heater a/c blower unit under the passenger side of the dash. There is a motor on the top of the housing that could possibly be stuck or on working.

My lexus rx 300 fan/ac is blowing on the wind-shield only and does not blow throuhg the instrument panel. what could be the cause?


How long have you been driving or owned a car? Your A/C is set on front "defrost" instead of main. Turn off the defroster for the front and select the switch to read "main" or if your A/C panel uses icons to display, press the one where it looks like the airflow is blowing air (represented by arrows) towards you and not the windshield. The arrows on your buttons or electronic display refer to which way the air is flowing. Choose the one you want where the arrows show the airflow is blowing out towards you and/or turn off your defroster. (If you have a knob to select airflow, turn it so it is no longer on "defrost" and it points to the main airflow blowing outward).

The defrost dosent work ,and the heater is not blowing warm air, and I can hear the fan blowing but there is no air,we replaced the waterpump and thermostat and still dosent work.


check your coolant level if the level is good then you need to check thermostat if it's not the thermostat then it could be the water pump or the heater core

2006 Envoy SLT air suddenly stopped blowing from vents


the resister block needs changing... oddly enough i'm unsure of what fan you are saying is not working.... if it's the front.. the resister block is located on the duct work under the dash for the air... near the fan... you will see a connector going into the side of the duct work. two screws and the block comes out... should be fairly obvious for the rear one but it will be near the fan.
