Power windows not working.

Did you check for battery voltage at the switch , with a volt meter before you replaced the main driver door switch ? Maybe you'll want to take this to pro ,instead of just replacing parts !

  >
• Is the resistance less than 5 ohms between the driver window control switch and the SJB; and greater than 10,000 ohms between the driver window control switch and ground?

Yes
Go To Pinpoint Test H

No
REPAIR the circuit. TEST the system for normal operation.

CHECK THE FUSES AND POWER WINDOW RELAY

loose body ground clogged fuel filter bad gas or fuel pump or wiring loose on fuel pump

REPLACE BUSTED FUSES

Shorted window motor

yes have the computer repaired and this should fix the problem. these cars are known for have the computers go bad.

they are bad about pumps leaking into alternatorand shorting out .the high pressure hose from pump to rack and pinion are also bad about leaking. the racks will leak around 100k.

Check your fuse box under the hood. A fusible link may be blown. I carelessly crossed jumper cables and ended up with no power to all these components as well. I located and changed the fusible link and everything is back to normal.
