    Why does heat comes out when the AC it turned on?
    Yesterday I tried turning on the AC in my 1999 Mercury Sabel, but the heater came on. Last week the AC was working fine.

      A faulty blend door actuator can do this. This is the small motor that moves the air door and mixes cooled air with heated air. It's posityion is determined by the temp control knob. You should see an immediate difference in the temperature of the air and the sound of the air as you move the knob from hot to cold and cold to hot. If you hear no change it is likely that the actuator is faulty and has become stuck in the heat only position. It is not hard to replace.

      When the AC was working I could hear the sound when switching from hot to cold but now I don't. How do I fix the knob if its stuck on the heat position? I've been doing some research and I was thinking about replacing the ac temperature switch, do you know of a website where I can find that specific part? Thanks for the answer.

      It is not a problem with the temperature control knob, it is the actuator that is supposed to move when the temp control knob is turned. Get a repair manual for your car and follow the steps and pics to replace the blend door actuator. >> http://www.autopartswarehouse.com/.../MIYH1759.html

      when you try to put the cruise on what works and what doesn't?

      1.) When you turn the cruise master switch on does the light light up?
      Yes: continue
      No: Check fuses and relays related to cruise control

      2.) If you set it does the light on the dash come on?
      Yes: Replace cruise control actuator
      No: Replace master control for cruise

      Hope this helps!

      It is possible that there’s a frayed wire in your fuel sender and when you put it inside your fuel tank it touched the fuel tank (body ground). Check the wires and connection of your fuel sender.

    Rear suspension problems. Tires hitting wheel well
    The rear suspension is not holding enough of the weight... when we go over a bump or out of a parkinglot the wheels hit wheel well.

      Your rear suspension components may be failing. Check the condition of your suspension components you can visit this link to have an idea how to perform it http://www.automd.com/.../

      If your car isn't sagging in the rear, and you don't have plus sized tires, and you don't have an excessive amount of weight in the rear then it might be your shocks. Go to the rear of the vehicle and bounce the car up and down when you stop bouncing the car it should go up then down and settle in that position. If it bounces more than that after you stop bouncing it then you will need to replace you shocks.

    Where can I find a key for the wheel lock?
    I had tires put on and they lost my key for the wheel lock. They never got back with tme to replace it. I need brake work now, but need the key. Thanks!

      Basically you can't. Mechanics generally just beat on a impact socket to remove locks. this may cost you, so go back to the tire place and ask them to remove or replace them, it has happened.

    My fuel gauge doesnt leave empty
    We just bought the car off of an old man and it works beautifully except for the fuel gauge not working. I was wondering if you could tell me what to look for. The gauge always reads empty and the low fuel light is always on.

      Replace the Fuel Level Sending Unit in the fuel tank. May as well replace the pump assembly also while you are there.

      Clicking noises can also result from too much tappet clearance in a valve, or a hydraulic tappet is not working correctly.

      Visit a mechanic to check that sound.

      You can use the "Find a Shop" feature of AutoMD for shops nearest you.

      If this is the DOHC 3.0 than the PCV valve is under the intake manifold. If the eighth digit of the VIN is an (S) than it is the DOHC 3.0 engine.

      Ok first, its never good to replace only one cat because chances are, the second/third will get busted soon, so you have to go back to your mechanic and do the job all over again (you will be paying thrice and your time for repairs will be wasted thrice as well)

      Replace both

      Since you said you are looking for a reasonable price, i can give you UNIVERSAL FIT cats, this means it has to welded or cut to fit.

      Bank 1 is usually on the left side if you are facing your car but sometimes its on the left, my tips is look which back is closest to you and that is your bank 1

      Let me rephrase my answer, your engine is horizontally placed so your bank 1 usually is the radiator side

      You have 3 cats by the way
      Radiator Side EAST82465
      Rear Under Car EAST70317
      Unfortunately we only have a direct fit cat for the rear firewall side DAV15650

      Thank You so much for the prompt response...Im curious as to why the mechanic is giving a quote for parts at 997.75, for just the rear cat, I've seen the prices on your site and im just trying to figure out if im missing something here.

      Best advice is to have the alternator rebuilt by a professional, there are some left that still rebuild alternators especially for classic vehicles you may have to ship it to them if you are not close to one. just do a google search for alternator rebuilding plus your zipcode you'd be surprised you might have one near you.

    My air bag warning lite is flashing a 51 code. How do i fix.
     
    • HouseCallAuto

      This code indicates a internal fuse has blown due to a short to ground in the firing circuit. But, this condition is no longer there. Inspect the front crash sensor harnesses for damage. Possible faulty clock spring. If the harness appears okay, recommend replacing the clock spring before installing another module, but the fuse may blow again if a unseen short should return.
