    Also have all 4 windows stop working

    I also have had all 4 windows stop working. However, we discovered a wierd glich as well. When I turn the key off the windows do work but only at a very slow and jerky motion. They work as long as the key is off for an unlimited time, not just during the few seconds of time that the car gives you when you turn off the car. Any other suggestions?

    Actually, if you do not open the doors, your windows, as well as radio should remain active for 20 minutes before being disabled.

    Disconnect the auxiliary water pump located at the front almost besides the battery in an upright position.

    See in the following,



    Post any differences with this action.

    What does disconecting the auxilary water pump have to do with the windows?

    Apparently I read in some of the BCM related threads that the BCM tests this device at start up and if detecting an overdraw in this test will shut down anciliary items that it controls including the windows, etc. Not my work but sharing what I read.

    When you turn the car off and the right conditions of temperature exist, auxiliary water pump runs along with the auxiliary fans to coll the engine down to certain temperature. During this phase if the pump and or fans are defective (drawing excessive from the battery, etc.) you may note much less power to operate windows up and down, etc., as described by one of the posters.

    Hopefully these notes trigger other ideas or a solution.

    Good luck.
