Daughter has a 98'Volvo s70. 1st drivers window would go down,but not up?(finally got it up 1day) now pass.side window went down but not up? even if pass. switch.??
well you should check the voltage at the connector...probably it's runnin' on reduced voltage because the MAIN ground connection is corroded...get a NEW battery, follow the Black cable to where it attaches to the ground/chassis....wirebrush the corrosion off of the MAIN ground connection...test the voltage at the switch (probably works okay now with restored ground potential~)
