I need to disengage the ABS on a 2002 Subaru Forester. It engages too early. Not very comforting.


The ABS only works when a wheel stops turning
The amount of pressure that it applies is governed by you foot pressure on the brake
IT will not activate on it's own early or late
From your statement , it indicates a disc pad / rotor problem or problem ABS sensors and that interfering with the ABS system will not fix the fault
Take the vehicle to a brake specialist shop for a proper diagnosis of the problem

Ac not working, air compressor clutch not engaging


Hi Adeyeri

Keep in mind that the Clutch won't engage for a few safety reasons.

Temperature inside vehicle
Temperature of compressor or pipes
Pressure inside pipes
Compressor jambed
Eg It's out of refrigerant Gas

You can momentarily engage the clutch by simply giving it +12v to the wire attached to clutch. Usually has a connector close by.
Or
If it has a Relay (click) in fuse box
You can by pass it with a jumper

A quick engage & disengage should allow you to detect possible problem.
But don't over ride the built in safety for more than about a minute.

Cheers
Hope this Helps

How do I fix my car air conditioning stopped when I accelerate


  1. Check the compressor has engaged. Identify the location of your compressor. Look at the pullyer and you should be able to see if it spining or not. The engine running turn the A/C on max cool, set fans high, and make sure that the clutch is engaging on the compressor. The pulley spins any time the engine is running. The center part of the A/C pulley only engages when the A/C is on. If the clutch is engaging and disengaging rapidly, the refrigerant may be low.

How do I recharge the AC on a 2002 Chevrolt Malibu?


The only way to know if a vehicle's air condition is properly charged is to use refrigerant gauges to determine the high side and low side pressure while the system is running. Without gauges, there are a few things you can check:
  1. With ambient temperature over 85 degrees Fahrenheit, when you first start the engine for the day, the compressor should engage and stay engaged. If it cycles off and on for more than one minute, or if the compressor fails to engage at all, there is a likelihood that the refrigerant charge is low. (If ambient temperature is under 85 degrees Fahrenheit, a small amount of cycling is normal, but the compressor should remain engaged for a longer time than it is disengaged);
  2. If the compressor is not engaging at all, momentarily place a wire jumper across the two pins of the refrigerant pressure switch connector with the engine running and the system on. The compressor should engage. If it does not, the system is not working properly. If it does, there is likely insufficient refrigerant in the system.

1994 gmc sierra ac compressor clutch


refrigerant added is by allowing the compressor to suck it in (low pressure side or suction side )until the system pressures are right
What you describe is liquid getting into the compressor causing the high pressure switch to shut it down until the liquid boils off

A/c is blowing hot air out


If your AC compressor does not cycle, (Clutch engages and disengages making the compressor come on and off) you should take it to a repair facility to have the system leak checked and the cycle switches checked then serviced appropriately to return it to it's proper functioning condition.

Just replaced the clutch and still wont engage or disengage


It can't both not engage and not disengage? If you can't put it in gear even with the engine shut off than there is something wrong with the transmission internally. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

''Hold At'' Subaru forester problem


I don't think you have a problem at all. when you turn the key on, the hold at light appears, this lets you know the system is engaged and ready to go,and will not turn back on unless the system is engaged during slippery conditions. Try disengaging the button,then turn the ignition on, I'll bet the light doesn't appear! Thats because its not supposed to when the system is disengaged. Dale

AC clutch engages and disengages constantly


the system is low on charge, as far as the attempt to add refrigerant u did something wrong, no sure what, the rapid cycling of the compressor is only caused by a low charge 99% of the time. Have u hooked up a set of gauges to check pressures?
