    Sounds like a bad ground. Do you have meters to test with?

    First start with the body ground off the battery to fender, or engine to firewall. The components mentioned except the ABS are at the left under dash/kick panel area. The ABS is grounded to the frame right under the driver seat/floor board area. Something in the area causing change when door controls are used, Ground not good to let all operate at the same time. Window stops radio & heater.

    Agree with prof, this could be a bad ground. Check the braded ground cable from the frame to the engine block near the right hand engine mount too.
