    The blower motor will not run.
    I have junpered the motor to the battery and it runs. I ran a ground wire from the ground side of the blower motor power plug to the ground terminal on the battery and the blower runs at mox speed. What is defective?

      Probably the blower resistor mounted in the heater / ac housing. Easy to replace and cheap part

      The blend door actuator is most likely the cause. This moves a door to control the temperature of the air blowing out by "blending" hot and cold air. When they begin to fail they can make a sharp skipping or snapping clicking whatever you wanna call it.

    Radio turns all to static when rear defogger is turned on.
    With car running, radio on, turning on the rear defogger/defroster turns the radio to all static. Radio works great otherwise.

    The computer keeps teeling me that my door is ajar or that the bck hatch is open. It beeps and turns on lights
    It happens randomly, almost every day. My local mechanic put it on a diagnostic and it showed nothing.

      Your local mechanic has to check the door inputs with a 2000 dollar scan tool. Not everyone has this, most do. Has to check door data when the door ajar light is on, may show fault codes as well.

    CD player addition : wiring
    is factory wiring harness present in all models, so all that is needed is to purchase cd changer and install it in trunk and plug it in, or do I have to purchase entire wiring harness. Radio has cd button on face.

    Why does my computer keep telling me that my door is ajar or that my back hatch is open?
    It beeps and turns on lights, making me have ao shut all lights off with the main switch which prevents me from having dashboard light at night. It also randomly ssets off the alarm.

      Inside each door there is a door ajar switch that can become stuck and tells you that the door is not closed all the way when it is closed all the way. Since there can be any of the 5 doors causing this (or more than one) it is best left to a mechanic with a scan tool that can see all the door inputs on the display which will determine which door is the cause. It is a strong possibility that the driver door is the cause but you cannot know without the scan tool.

    Low beam lights do not work when turned on
    High beam lights come on when turned on

      Either both headlamp bulbs have burned out low beam filaments or the lighting control module needs to be replaced.

    Sometimes when i start my car the interior lights do not come on and it takes a few minutes before the power windows run

      I know that your cause here is one of two things, and not sure if you can handle the repair yourself. Either the General Electronic Module is bad or the Fuse Box is bad. there is a way to diagnose this but it requires some basic circuit testing while the problem is present. Do you need this detailed further?

    What controls the air flow from the different vents, ie., panel vents, defrost, floor, etc. Where is the part ?
    Air will only come out of the defrost and floor vents and not the panel vents, no matter what setting the AC unit is on, i.e. max AC, automatic, etc.
    • CVO

      This vehicle has a panel / defrost actuator and a floor mode actuator.
      A malfunctioning panel / defrost actuator is the cause of the problem described.The part is inside the dash.
      See this Fig. EATC, Page 02 (2003, System overview) at ( under the wiring diagrams ).

      It may be normal because I seem to remember that there is a switch inside that controls every thing.If you have the hand book it would help if not check out the switches for interior and dash .It has different positions.

      If the headlight switch is the knob type which you can turn all of the way to the left to control interior light,its probably a bad switch.You might also have a short causing the problem

    Auto locks used to work
    Bought the car a month ago and the auto locks worked. Three days later, a yellow indicator on the dash came on (it looks like a person sitting with an airbag in its face). The indicator will blink (blinks five times, then stays on). Since then, auto locks haven't ...

    When headlights are turned on, there are no dashlights. But both turnsignal indicators light up. What's causing it?
    We have changed the headlight switch and checked all the fuses.
    • wbrockstar

      1st- check to see if the fuse for the dash lighting,etc is good
      2nd- if fuse is good,then it could be burned out dash bulbs or the dimmer switch might have went bad
    • John's Auto Repair
      Sounds like a feed back circuit caused by a bad ground. check dash light ground under dash

    Ac/ blows cold on the floor and defrost
    ac / blows cold on the floor and if you turn the fan down to low the vent on the dash may open and blow cold, I want to know how many vent door actuator motor does this car have ? Does it have one on each side of the dash

      I do know that there is a sensor that kicks in when the engine warms up the fan motor should slow down and change the air flow from the Defrosters to the dash board (face ) outlets, my AC doesn't blow anywhere except out the defrosters all the time.-- I am wondering where the sensor is located and is there a selonid that changes these vacum accuated damper doors that control the flow direction?
      6/30/2013 CVO
      Check the panel / defrost actuator ( it determines the air flow location ). The actuator is made out of the plastic materials, a cracked could have stopped the synchronizing gear operation.
