When turning on air control lower settings do not work last two higher do. This seems to have an effect a/c. A/C shows itself on when the air control is in the lower setting (which do not work)and shuts off when air control is turned to the high setting's (which) do work.

    joe7379- It does not matter if the a/c is on or not, the fan motor control will not operate the the fan motor in the 1,2, or 3 settings but will blow air on # 4. If I turn on the a/c the green light comes on indicating it is on and cold air is present. With the a/c on and the green light indicating it is on, it will remain so as long as the fan motor control is on 1,2 and 3. but as soon as you turn the control to # 4 the a/c shuts off and the air blows from the vents. No air blows from the vent on 1,2 and 3.

    Sounds like faulty wiring possibly corrision and causing a short in the system. Typcially a fan will work on all levels unless the wirong or switching unit has a short that casues the AC to shot down. And yet there is a control module for switching between the SC and speed slecetion for the fans. If that is malfunctioning it could cause the same reaction your getting as it does not know where to set the fans in accordance to the airflow and tempature being drawn.

It seems like there is a malfunction in the A/C control board you will have to get it replaced.

Hi
It could be many things such as a leak in the a/c system, blend door/motor, clogged orphus tube, or an electrical problem in the a/c circut- i usually recomend that a/c work be handled by the professionals due to health hazards and most people don't have the right tools to do the job..

thank u

What does error code E8 mean on the dyson hot/cold fan mean?


Possibly it doesn't like the heat setting and shuts itself off to prevent melting or possibly fire. Be sure that it is not blocked so cold air goes in freely. Try to lower the temp setting and see what happens.

P507 buick regal 1998


P0507 - Idle Air Control (IAC) System RPM Higher Than Expected

This P0507 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM. In the case of GM vehicles (and possibly others) if the idle speed is over 200 rpm higher than expected, this code will be set.

Potential Symptoms: Most likely you'll notice the idle speed is higher than normal. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.

Causes: A P0507 DTC trouble code may be caused by one or more of the following:
* A vacuum leak
* Leaking air intake after the throttle body
* EGR valve leaking vacuum
* A faulty positive crankcase ventilation (PCV) valve
* Damaged/failed/dirty throttle body
* Failed EVAP system
* Failed IAC (idle air controller) or faulty IAC circuit

Possible Solutions: This DTC is more of an informational code, so if there are any other codes set, diagnose them first. If there are no other codes, inspect the intake air system for air or vacuum leaks and damage. If there are no symptoms other than the DTC itself, just clear the code and see whether it returns.

If you have an advanced scan tool that can interact with the car, command the idle higher and lower to see if the engine responds appropriately. Also check the PCV valve to see if it's blocked and needs to be replaced. Check the IAC (idle air controller) if equipped, verify it's operation. If available, try swapping in a new throttle body to see if that fixes the problem. On Nissan Altimas and possibly other vehicles the problem may be fixed by having the dealer perform an idle air relearn procedure, or other relearn procedures.


Hope this helps; keep us updated.

Should clutch fan turn freely with engine off ? if its locked in and the temp gauge shows it running in the middle would it still effect the heater temp


It should turn 'freely', that is it should spin about 1 1/2 revolutions when spun then come to a stop. They are designed to 'slip' at lower temperatures, and 'lock' when the engine is running at higher temperatures. Your heater temperature is affected by the engine coolant thermostat and the blend door in the heater core itself.

Air flow out of A/C (HVAC) seems to be partially blocked. Noise increases with increased fan speed settings, but flow barely changes. Even on maximum setting the flow is not enough to reach driver or...


One of the Actuators for the doors inside your dash that controls and diverts air might not be working correctly. You may have to either replace the Actuator or Replace the A/C Heater Control. Your vehicle does not come with a Cabin Air Filter.

You have a faulty switch. Go to the salvage yard and buy a used one, pull off the trim panel and replace it. I just did one of these last week with the same symptoms.

2002 Honda Odyssey fan only works at high speed. The A/C compress


Usually when the blower fan only operates on hi speed, its because of a failed blower motor resistor. You still have hi speed because on hi, the power going to the blower motor goes directly to it, as opposed to the lower speeds, when the power is routed through the resistor, thus lowering the voltage, which in turn lowers the speed of the fan. The resistor is usually located near the blower motor itself, under the hood back near the firewall.
