Question about Cars & Trucks

1 Answer

Can anybody tell me if there is somewhere (under the dash?) where you can clean the air-conditioning ducts? I seem to recall someone saying once, on a previous car I owned, that there is a receptacle at under the passenger side dash which you need to clean-out occasionally? Also, I have 'leaf-noise' whenever I put the fan above '1'?

    Thanks for the quick response. Two dumb questions: what's the "blower cage" and where is it? And are there any tricks to "pulling it out"?

SOURCE: Heater fan only works on high speed 4.

sounds like the switch is bad. Test the power coming in to the connector and use jumpers to get the fan to operate at all 4 speeds. if it works then it the switch.

SOURCE: Air conditioning fan makes loud noise the faster you ru it.

Concerning your broken vent -- this can be caused by a broken linkage or a malfunctioning servo motor as well. these vent have air ducts the sway back and forth to adjust the dual air flow function. if the servo o linkages are malfunctioning or not connected for some reason, it will not allow total control of the air flow and temperature range. Now, if you have a combination of a flow error and temperature error as well, thai can be caused by a combination of the two.

In this case, you will need to inspect the linkages as well as the servo motor function as well. in addition, i would test the air temp sensors for there operational value. they control the temp when you adjust the coll or hot function.

Concerning the Loud noise coming from the blower fan---

This issue can be caused by a misalignment within the blower housing or, it can also be caused by some minor damage within the motor itself, causing it to rotate in a erratic manner, in return, forcing it to rub against the housing itself. the best solution here is to extract this blower fan housing and inspect for lose fan propeller and motor stability. replace parts accordingly.

PLease rate and have a great day:)

SOURCE: thumping rythmic noise from passenger side dash

Don't you just love it: thump, thump, thump, thump, pause, thump, thump...? I've found the best solution is to use compressed air as used in cleaning the keyboard of your laptop. Take a very thin (but strong) metal strip about 1/32" thick and gently place inside the edge of the recirculate button. VERY GENTLY depress the recirculate button just until the thumping stops. Apply just enough upwards pressure on the strip to hold the button in place. This creates enough of a gap for the air to blow behind the button. hold the can of air no more than one inch (1") away from the strip and aim directly to the left or right of the strip. Once you've cleaned from behind the button completely, that mother thumping (LOL) song will be no more.

SOURCE: 2001 New Beetle A/C fan noise

I think it is the cabin/ pollen filter. The noise is louder on normal AC operation cos thats when the air is being pulled in through the filter and the sound decreases with recirculate because the filter only functions for outside air.
Need to use a credit card or similar to seperate and move the upper dash centre piece towards windscreen, it clips off. Then open the 3 x torx screws and lift the dash on the passenger side. then remove the plastic cover (oddly shaped) it has about 7 screws, then twist and remove, it requires some real effort, then pollen filter is visible. replace filter and voila! it would make your AC perform like a new car again!!
Hope it helps, Yusuf Johannesburg-South Africa yusuf.ginnah@poynting.co.za

Where is the air conditioning sensor. We were told it is under the dash and the whole dash has to be dismantled. We were also told there is more than one air conditioning sensor.This is big bucks and not...


The upper and lower duct sensors are divided into left and right zone operation. The left side upper and lower duct sensors will only effect the operation of the left air temperature actuator and the right side upper and lower duct sensors will only effect the operation of the right air temperature actuator. The duct sensors are used to measure the temperature of the air exiting the ducts.

The inside temperature sensor operates within a temperature range between -6.5°C (20.3°F) to 57.5°C (135.5°F) . If the sensor is shorted to ground, the system will operate in the maximum cooling mode. If the sensor is shorted to voltage or open, the system will operate in the maximum heating mode. The ambient sensor operates within a temperature range between-30°C(-22°F) to 51°C (123.8°F) . If the HVAC control module (IPM) has determined that the ambient air temperature sensor has failed, the IPM shall display "- -" in place of the ambient air temperature. If the sensor is shorted to ground, the system will operate in the maximum cooling mode. If the sensor is shorted to voltage or open, the system will operate in the maximum heating mode.

You are not makining sense when you replaced a P/S belt and A/C is now non op You need to know what the pressure is Leave the sensor alone the problem reside in the engine compartment

My heat want get hot but it blows


For one reason or another your heater core is not recieving any circulation. It could be a frozen heater switch valve or ( diverter valve ). That is located in line under the hood on one of the heater hoses running into the firewall. Check it for operation. If that is okay check for plug in heater hose or a pinched condition of supply lines. If the blower blows but you dont feel any air movement then the
air control gates under the dash arent working. They are vacuum controlled and hoses get old and crack and break or pulled so check all the vacuum elements on the climate control center under the dash. If you feel air but not from the vents then a length of duct work came disconnected or it cracked somewhere.

Water leaking under the dash


If on the passenger side when the air conditioning has been running, most likely a clogged air conditioning drain hose. You can located it by reaching under the dash in the passenger foot well. I have cleaned mine by removing the end of the hose from the firewall grommet and inserting a wire in the hose to clear the clog, then used a shop vac to **** out the debris through the hose. I did this several times. Take a container to catch the water as once you clear the clog the water will come running out all over your head.

Air conditioning duct doors operating poorly


It could be a vacuum hose leak. With the car running listen for hissing sound either under the dash or under the hood. Or if the car has electric actuators on it one of them may have failed and stuck in place.
