Hi sister just purchased a 91 740 dark green on black interior. The seller was not up front with her. She just realized today the previous owner failed to tell her was the driver side window went down partway stopped and then went down the rest of way but will not come up. When I looked at the car all windows go down from master window switch but do not go back up. The only way you can get other windows back up is to use the window switch for each door. Does this mean the master window switch is at fault as I am not familiar with rwd vintage volvos or is their a relay or another common issue. Also does this mean the drivers door regulator is bad as well or is it just the switch. Any help would be appreciated.
I am looking for a master window switch, and speedometer sensor located on trans-axle for this car as it has the Rex-regina system as previous owner told me. If anybody has any spares please let me know, I am just mad the previous seller was not upfront with her as they juiced the a/c system as well.
