Windows will not go down, the heater switch stopped working?

Did you check all fuses or only one? Also, the ABS light is most likely a bad sensor at the one of the wheels. You can have the computer scanned at a nationally recognized parts store to check for the source of that problem. Most do it for free.

As far as the other items, check under the hood in the power distribution center. Make sure all fuses and relay are good and not loose. If all looks good, then you will need to start checking for power at the fan motor, window motor.

Let me know what you find or if you have other questions.
