    Rear windows only work from front door wtf?

    Anybody ever heard of this? They work fine from the front door but neither rear door operates them. No, the protective window over-ride switch is not engaged... they don't work in either setting for that matter as far as troubleshooting that switch. I do have a replacement PCM but not sure if they did this with the stock computer... just noticed it actually.

    FWIW sometimes the windows/sunroof will act funny when the key is removed but you haven't opened a door yet... if the front windows are going auto-up and you raise the rears, the passenger front window will start going down by itself. Funny stuff hard to describe, luckily not a big deal. Thanks for any insight, maybe somebody else has seen this.

    I'd start checking electrical grounds in your vehicle. If you are trying to change one window and it makes a different window move you have electrical issues that need to get sorted out.

    One of the main ground connections that people have problems with is the negative wire that connects at the base of the hood strut. Search on the forum for more information, but people have had all kinds of random problems that went away when they disconnected that wire cleaned the connection and put a star washer between the frame and wire to improve connectivity.
