      If the back of the car is low, indicating that the air suspension is not working, and the air suspension light is on, check the fuse first. If the fuse is all right, check the air suspension switch in the trunk and make sure it is on. This switch is used when the car is in for service. Always turn off the switch before lifting the car, because the sensor will think the car is rising and keep the air bag valves open, ruining the rear air suspension.

      Turn the ignition key with the engine off. Listen for the compressor to come on while pushing down on the rear bumper. If it does not come on, test the switch terminals for power, using a circuit tester. If one terminal has power and the other does not, replace the switch. If there is power, turn the switch to the off position, raise the vehicle and place it on jack stands in the rear. Inspect the leveling switch on the axle, making sure it is not bent and is connected. Use an ohmmeter for this test. Pull the electrical connector off the switch. Loosen the arm of the switch from the axle. Test the switch with the ohmmeter by checking across both terminals while slowly moving the arm. There should be no continuity with the arm down. As the arm is raised, there should be continuity. If not, replace the switch. If there was continuity, connect the arm and the electrical connector.

      Put a floor jack under the axle and raise the axle to the point where it is just beginning to lift the car off the jack stand. Turn on the ignition. Turn the air suspension switch to the "on" position. Use the circuit tester to check for power at the leveling switch. If there is power, turn the air suspension switch to "off" and lower the car. Access the air compressor in the front, under the hood, and check the electrical connector for power. If there is power, check for a good ground. If both are good, replace the compressor. If the compressor works and the car does not rise in the back, replace the air bags.

      Did you already locate the cause of the leak (power steering hose/ power steering pump)? Did you already try to add power steering fluid with sealer?

    Where is the power steering fluid intake?
    • EG9 K20A3

      If you look at your power steering pully it will have 3 holes in it...thats is where your P/S pump is. follow the line until you see the reservoir.
    • EG9 K20A3

      What do you mean intake? The power steering system of your Cadillac is made up of two power steering hose which include a low pressure hose and a high pressure hose. Commonly used in making a high pressure hose is a reinforced synthetic compound with hose fittings that are commonly doubly compressed. A low pressure Cadillac Power Steering Hose on the other hand has similar features but it is not equipped with compression fittings since it is not subjected to high pressure. It is responsible for the transport of oil coming from the steering gear to be taken back to the oil pump. High pressure oil is carried, as implied, by the high pressure hose. The oil comes from the power steering pump to be transferred into the steering gear.

      So technically, if its the intake you want then look for the one with fittings. But we dont really call it an intake.

      I certainly could have been more clear... where do I pour the fluid in? I don't see the little cap that is in my owners manual and it does not show where it is, it shows only a picture of the cap (?)

    What is a tire monitor?
    • Spoon Sports
      3/9/2012 Spoon Sports
      Its an annoying piece of equipment which just monitors tire pressure. Its annoying for the following reasons (Pardon my rant)

      1. Its expensive when it gets busted
      2. It makes me feel stupid, i mean thats the reason God gave me eyes, so i can see if its flat or not
      3. If it gets flat while i am driving, God gave us the sense to feel it which is not hard nor unoticable really


      4. Or if it gets flat while i am driving and for some odd reason i didnt feel it, i have other people to warn me

      As you may already notice, all of things to know when a tire is flat is free of charge :)

      You cannot fully handle anything productively about this yaw sensor without the use of a shop grade scan tool to view live data.

      1. Check the "YAW" sensor voltage reading on scan tool or with a voltmeter, it should be in the .18 to 4.84 range.

      2. If not, disconnect the YAW sensor and verify the signal wire has no voltage on it. If it does, trace wire for a short. If no voltage, verify the YAW sensor has a good ground, if so replace the sensor. This is a $200 sensor.

      3. The yaw sensor is under the carpet and is accessed by moving the passenger seat fully rearward and lifting the carpeting by the seam.
      3/3/2012 ricer
      Thank you for the information, is it sometimes true that you can disconnect the sensor and then reconnect and it may reset?
      3/3/2012 HouseCallAuto
      Often in automotive electronics a disconnect and reconnect sometimes does good stuff, there are no rules here and there are a lot of gray areas. Try it as it cannot do any harm.

      If you are getting a service ride control your compressor is the cause unless there is a sensor wire that you didn't hook up right or the sensor is bad.

      Other than that, i cant think of any other reason.

      not getting a service ride control lite, but after the brake job,my abs and my traction control lite stays on
    • HouseCallAuto
      2/16/2012 HouseCallAuto
      Your cause is *probably* a bad compressor. The part of the compressor that goes bad is the exhaust solenoid which is integral with the compressor and is not serviced separate from the assembly. But, if you can perform this procedure >>

      1. Test for B+ to the Orange wire of the compressor/exhaust solenoid.

      2. Ground the White wire, pin E of the height sensor, check for car to drop, with weight on the wheels.

      3. Ground the White wire directly at the exhaust solenoid, check for click, check for rear suspension vent.
      2/16/2012 greenleggrey
      so you think the brake job is just a coincidence? traction control and abs lite is on after they did the brake job
    • HouseCallAuto
      2/16/2012 HouseCallAuto
      I gave you the circuit test to do. In the rear of your car there are height sensors. when your car is put on a lift for service these sensors are allowed to extend beyond their normal range of motion. It is possible that if one of these sensors failed when the rear suspension extended when the car was lifted. The sensors are supposed to be able to handle this. That is the only link I see relating to work being done and then having a problem immediately. No matter what, proper diagnostics has to be followed to determine a cause. cannot just say this part is bad because they did this. If a height sensor failed you cannot blame the repair facility for having your car on their lift. I would think though, if you were my customer and it was my shop, I would gladly look and see if I could have done anything to cause this to happen beyond the car beyond the car simply being on my lift.
      2/16/2012 HouseCallAuto
      I don't think it is a coincidence, no. The car has to be checked by someone that has the knowhow and ability to read and interpret the fault codes for the air suspension and the ABS system. The codes tell a story.

    I hear a rubbing sound when car leans to left
    I changed wheel hub and all linings and still I hear the rubbing sound when car is leaning like when I'm on the highway not just regular turning
    • Spoon Sports
      2/24/2012 Spoon Sports
      "when car is leaning like when I'm on the highway" - How can a vehicle lean on the highway without turning, i mean if that was the case have you checked your shock absorbers? Have you also checked your fender linings if the are dangling and hitting your tires?

      If i was just there i can easily pinpoint that rubbing sound, alas, im online
