1999 Audi A4 Climate Control Removal/Installation

Does the Climate control Unit have any bolt that must be removed prior to it's removal, or does it pull straight out. Should I disconnect the battery before removing it? Thanks!

    Is changing the a/c control a simple swap out or is it much more involved? It appears straight forward from the looks of the back of unit...

You have to remove the trim panel around the stereo/climate control to expose the screws that hold it in place. Once you do that, and the screws are removed, it pulls straight out and unplugs. No need to disconnect the battery and no tricks to it once it slides out.

How do you remove radio, from my 2001 dodge neon, that just went dead, for no reason. I replaced the fuse on the side of dash board. Still nothing.


Safety Precautions
  • Before removing the stereo or any other electrical component, it is vital that you first disconnect the grounding cable from the Neon's battery. The grounding cable connects the battery to the frame or chassis of the vehicle.

    Use a Phillips-head screwdriver to loosen the grounding cable's camp from the negative battery lead. Make sure to rest the clamp away from the negative lead post until the removal is complete.
  • Remove the Dash Trim Panel
  • The dash trim panel that surrounds the Neon stereo needs to be removed to access the stereo. The panel contains, but is not connected to, the climate control knobs on the dashboard.

    Grab the panel at the bottom corners and pry it from the dash. You will likely be able to remove the panel without the assistance of a trim pry tool, but if you are having difficulty removing the panel by hand, wrap a thin cloth around a trim panel removal tool or flat head screwdriver to remove the panel.

    Once the lower edge of the panel is relieved from the panel, you can work your hands (or flat pry tool) around the perimeter to separate the remaining edges.

    Since the panel is not connected to the climate control knobs, you will not need to disconnect the wiring to the knobs. The panel, once free, can be set aside until you replace the stereo.
  • Remove the Stereo
  • The Neon stereo deck is held into the stereo mounting bracket by 10 millimeter bolts on either side of the radio. Remove the bolts and store them in the ashtray for safe-keeping.

    Pull the stereo from the dock. The unit will easily slide from the mounting bracket with an even pull from the left and right of the stereo. Pull the stereo far enough to reach the wiring on the rear of the radio.

    The wiring to the stereo includes the antenna, the power supply and the speaker wires. There may also be patch cables connected if an amplifier is connected to your stereo system. Pull the cables from the stereo. The antenna and power supply are single cables. The speaker wires (and patch cables) will be grouped by wire binders. The plastic wire binders should be pulled as a unit. Do not pull the wires themselves.

    Once the wiring has been disconnected from the stereo, the unit will be completely free from the Neon.

    If you plan to operate the vehicle before installing a new stereo or re-installing the factory deck; reconnect the grounding cable to the negative battery lead. Otherwise, leave the cable away from the negative lead until all of your work is completed.

    Stock radio


    removed the panel below the radio, clips hold it in and you have to yank it out without damage. then there are two 8mm head bolts behind that panel facing up. they hold the whole frame for the audio and climate controls. then push on that frame with your fingers to pop out the whole panel that the radio and the climate controls are mounted to. then simply disconnect the harnesses and remove the climate controls(three screws and the dials pop off). now you can get to the four 8mm bolts that hold the audio unit in.

    Illumination lights are out on climate control unit for 02 highlander


    This solution has two basic assumptions. (1) Your fuse is fine and (2) the problem is a blown bulb and not a wiring issue.
    That having been said, you're going to have to CAREFULLY remove the audio/climate control trim panel. Use a trim stick (if you can find one) or a taped or cloth-covered thin flathead screwdriver and GENTLY but firmly, pry the trim to release the clips. There are six clips holding the trim panel. Two on the bottom, two on the sides just under the vents, and two at the top corners.
    Next you're going to have to remove the control assembly. There are 6 bolts holding it in place. Remove the bolts then pull out the assembly slightly so that you can disconnect the electrical connectors on the back of the unit. Do NOT pull the wires directly or you can cause serious damage. Only pull on the plastic connectors holding the wires. After all the connectors are unplugged, paying attention to where they come from so that you plug them back in correctly, the unit can be removed.
    Next you're going to have to remove the back cover of the unit. To do that, first remove the two side bolts from the mounting brackets on each side attached to the climate control assembly. Then remove the back cover by unscrewing the six screws along the sides of the back cover and the two recessed screws at the top. Once the back cover is removed, you should see a light blue plastic piece with a screwdriver slot in the middle of it. That's your bulb. Take out the old bulb, put in your new one and reverse everything you just did to put it all back together again.
    If you've done everything right, your unit should be illuminated once again.
    Good luck.
