Re: cabin air filter

On an old car of mine, one of the vacuum hoses in the engine bay got soft from getting oil on it and collapsed, preventing vacuum from getting to the controls. Since it sounds like there is no vacuum to anything, I would suggest starting in the engine bay. There should be a line that runs to the HVAC controls. I don't know, however, which one it is. Check that first, and then hook up the vacuum pump. Also, under the dash there are vacuum motors, you can use the vacuum pump to test those individually. Sometimes the control device behind the selector knob goes bad and allows leaks. Listen for hissing noises. There is also a vacuum reservoir hiding somewhere, probably in the engine bay. It will probably look like a black plastic ball. You need to check that (and the line to it) for leaks. When there is no vacuum, the default setting is defrost for safety, to ensure you can have a clear windshield.

Re: cabin air filter

cool but this sounds like a job for somebody that knows there way arround the engine im kind of an idiot i mean i know just the basic stuff like tune ups and brakes but when it gets into this yea im screwed but i drive a firebird and love this car

o silver bird lol.

You can do it your self. just take your time, research and take your time haha

Re: cabin air filter

i stress out very quick is there like a how to book or website?

Re: cabin air filter

I couldnt tell you any where to research other than google it. You could go to auto zone and buy a book on your car. They now sell alldata cd's for your car. You get one year to print off all the onfo you think you will ever need. hahaha. Its like $28 I think. That would be my number one recomendation if you do have tools.

Re: cabin air filter

alldatadiy .com Its totally worth the price. (there is no space, just beating the spam program on the boards).
it tells you the part numbers, tools needed to fix problem, related problems, where things are located, what happens if it stops working, give you fix times so you know the dealer isnt screwing you, gives you recalls, TSB's.. I subscribed for 5 years on my car. it was the best deal. but you can do it for a year at a time. its everything you need to know about your car. its kinda hard to find things at first, but there is a search.


you do vacuum leak on search you get this: it has photos,

HVAC Control Vacuum Harness Replacement


1. It is not necessary to replace the entire vacuum harness if there is a localized leakage or collapse in the vacuum hose. If there is a localized leak or collapse in the vacuum hose, repair the vacuum hose: 1.1. Gut the vacuum hose. 1.2. Insert a plastic retainer into the vacuum hose.

1. Remove the Heating, Ventilation and Air Conditioning (HVAC) control.
2. Open the Instrument Panel (IP) compartment. Push in on both sides of the IP compartment. This will cause the IP compartment to drop open completely to allow access to the vacuum harness.
3. Disconnect the vacuum harness connector from the vacuum selector valve.

1. Disconnect the vacuum harness jumper from the main harness connector.

INSTALLATION PROCEDURE


Connect the vacuum harness jumper to the main harness connector.

1. Connect the vacuum harness connector to the vacuum selector valve.
2. Close the IP compartment.
3. Install the HVAC control.

Vacuum Hose Harness Replacement


REMOVAL PROCEDURE


1. Remove the Instrument Panel (IP) carrier.
2. Disconnect the vacuum hoses from the actuators.
3. Remove the vacuum harness.

INSTALLATION PROCEDURE


1. Install the vacuum harness.
2. Connect the vacuum hoses to the actuators.
3. Install the IP carrier.

here is the discription and diagram of the vacuum lines with motors and look at #3 on the pic.. its your vent vacuum...

The engine vacuum regulates all of the actuators (3,10 12 and 13) (except the temperature valve) in the heater and air conditioning (A/C) evaporator module. The vacuum is drawn from the vacuum tank (1). The tank is mounted to the right side body rail.

A vacuum selector valve routes the vacuum to spring-loaded vacuum actuators (3, 10, 12 and 13) on the heater and A/C evaporator module.

During conditions of low engine manifold vacuum, a check valve in the vacuum source hose prevents vacuum in the vacuum tank from bleeding back to the vacuum's source.

The mode control regulates the vacuum selector valve. At each mode control position, the valve performs the following actions:

* Directs vacuum to the specific hoses in order to overcome the force of the spring within the actuators.
* Vents the hoses to normal air pressure. This action allows the spring to expand. The expansion results in the proper positioning of the valves (doors) for the selected operating mode.

The vacuum (BI-level) (10) and vent valves have two-position vacuum actuators. When vacuum is directed to either actuator's vacuum chamber, the vacuum pulls in a flexible diaphragm. The diaphragm forms one wall of the chamber. This action draws a movable shaft attached to the diaphragm. The shaft is linked to the corresponding valve. The shaft operates the valve when the vacuum is applied.

An external spring moves the shaft back to its original position when the vacuum chamber is vented to normal air pressure. The shaft, in turn, returns the valve to its original position.

The heater and defrost valve (13) uses a three-position vacuum actuator. A three-position vacuum actuator has a diaphragm with a spring on both sides. At rest (no vacuum applied) the diaphragm is in a mid-position. This allows for a blend mode. Apply vacuum to either end of the diaphragm in order to move the heater and defrost valve to either stop. This action directs airflow to either the defroster outlets or the floor outlets.

When air is directed to the floor outlets, as in the HEATER setting, a small amount of air still bleeds through the defroster outlets. This action helps eliminate the refogging of the windshield.



There is SOOOO much info on this HVAC. and Im just talking about Vacuum leaks in hte HVAC. so go to alldatadiy .com buy a subscription, get your car info, type in vacuum leak under search, go to HVAC, and look around, tells you how to take it apart, how to put it back together. how to diagnose a problem...

I mean hell there is even a TSB on an odor coming from the air conditioning and how to fix it.. Its microbial. lol I recommend this program to EVERYONE.. but if you need anything else. Just let me know..

Re: cabin air filter

COOL:banana: i can prob try and fix it wish me luck its gonna be a long day for me:work:

Re: cabin air filter

btw, if you work at autozone, you get it a LOT cheaper ;) At one point in time, it was free to me :(

[silverbird02]

Re: cabin air filter

yea autozone sucks they said that my car doesnt have that then i went to Oreilly's and they had it in stock so idk whats the deal is if i have one or not
