SOURCE: my 2004 audi a4 windscreen wipers move across the

First you must diagnose why windscreen wipers going slow and/or stopping.
In order to find out the cause of wipers stopping you can try follows: 1. Carefully extract the wiper arms from their axles (two pieces). In some cases you need to use an extracting tool. Heed of the windscreen !!! 2. Disassemble the plastic covers from the bottom of the windscreen. 3. With the bonnet up you can start the engine, (transmission in "N" or "P" position and parking brake on). Now you must switch on the control lever of the wipers, and go to the engine compartment. If the wiper motor runs let the wiper motor running for a few minutes and switch off. Go to the step 4. If the wiper motor do not runs you must check first the electrical feeding of the motor. It is necessary to unscrew three bolts of the mechanism and disconnect the electrical coupling (difficult assurance). If the electrical feeding is OK you must replace the motor - steps 5, 6, 7. If not you must check electrical connections, the control switch of wipers and electric cables. 4. Now you must check the two bearings of wiper mechanism with your hand. In the most cases the left bearing is out of order (is very hot). This is the most encounter fault of the wipers running at Audi. 5. For have enough space to manipulation the wiper motor together with their mechanism you must extract the plastic cover of the engine computer box, and extract also the box screws. Then you can move slowly the engine computer box, just for a few milimeters. 6. You must disconnect the electrical coupling of the motor (difficult assurance), unscrew three bolts of the mechanism and extract together with the motor. You must move them slowly between windscreen and engine computer box until the wiper motor go out together with the mechanism. This is the most difficult operation! 7. Now you can repair the bearings, replace entire wiper mechanism or replace the wiper motor. It is not very simply, but it works.
Heed of the windscreen !!!
Refit all in reverse order.

Have you recently put a stereo in this car? The vent selection is vacuum controlled and it is common that the lines don't get put on right when someone puts a stereo in.

SOURCE: Hello, I have no air flow

The first thing I would check is the blend door actuator. This is located under the dashboard towards the center, move the controls while looking underneath so that you can locate it. Once you locate it call the dealer for the replacement part before you take this one out.

Is the metal flap on Maf sensor on 92 Lexus es300 supposed to move with gas pedal if car is not running? Will a bad maf cause no apart or a no start condition?


No. The metal flap in the mass aiflow sensor is not connected to the throttle control. The air moving through the mass airflow sensor moves the flap. The flap works a variable resistor inside the mass airflow sensor. The more (and faster) the air is that moves through the sensor, the farther the flap will move...that is how it measures how much air is entering the engine....that is what a mass airflow sensor does.

A bad mass airflow sensor can cause all kinds of fuel control problems that can range anywhere from a hesitation on acceleration to a complete engine no-start condition.

Check the blend door cable for proper attachment to the control panel and to the blend door. Try opening the door manually to see the you can get hot air out. If not, the door may be broken inside the heater box. If yes, correct/adjust the cable attachment for proper operation.

1998 Cheyenne blower only blows to floor vents. Heat and a/c and blower fan speed work fine .


the slider switch to direct the airflow is connected to a cable which is connected to a flap which directs airflow to the desired vents. something has gone awry. you can most likely pull the heater control unit and see if the heavy wire cable is off at that end. if not it is at off at the other end or the flap has broken or popped out of its swivel.

Heater is blowing only cold air. both hoses for heater core are warm. what you think, main flap is stuck or is something else??


Hello there..Its two things..If your saying that the heater hoses are hot into the car,,either the blend dorr they call it thats what changes from cold to hot,the flap as you say,or the heater controller that controls it is bad..The dial on the dash that says cold to hot..Shut car down and listen for the flap to open and clse when you change it to hot to cold..If you hear it moving doesnt neccisarily mean that its working it could be broke from the flap and just spinning around or the flap its self is broke,or the heater controls are bad,,Hope this helps you and have a great day

SECTION 412-01: Air Distribution and Filtering 2001 Focus Workshop Manual DESCRIPTION AND OPERATION Air Distribution and Filtering The new heating and ventilation system ensures even air distribution.
The temperature control and air distribution flaps are controlled by two operating cables. All vehicles have a recirculated air function, with the flap controlled by a servo motor.
Air is supplied to the windscreen and side windows regardless of the air distribution setting.
The clean air filter is fitted as standard in most countries. This cleans the incoming fresh air of pollen and dirt particles. It must be renewed after every 40,000 km under normal operation conditions, or after 20,000 km under difficult conditions. If no clean air filter is installed, a plastic grille is fitted over the air intake. This can easily be replaced with a clean air filter.
Air distribution operating switch
Face level The main flow of air enters the passenger compartment at face level.
Face level/floor level The main flow of air enters the passenger compartment in equal parts at face level and floor level, and a small amount flows to the demister nozzles of the side windows.
Floor level The main flow of air enters the passenger compartment at floor level, and a smaller amount flows to the demister nozzles of the side windows.
Demist/floor level The main flow of air enters the passenger compartment in equal parts at the windscreen and at floor level, and a smaller amount flows to the demister nozzles of the side windows.
Demist The main flow of air enters the passenger compartment at the windscreen and a smaller amount flows to the demister nozzles of the side windows.
Air distribution operating switch Air distribution operating cables
NOTE: The Bowden cables for LHD and RHD vehicles are identical. However, they are fastened to the air flap operating mechanism with the respective reverse side of their connectors.
The air distribution switch operates with two Bowden cables. The cables operate the air distribution valves in the heater housing.
To remove and install the cables, the rotary switch must be turned as far as it will go to the left. The air flap mechanism engages easily in this position, making the installation of the cables easier.
