Question about power windows

[clean8485]

I recently purchased an '87 Olds Cutlass Supreme Brougham 4 door sedan. The car is pretty much loaded with options, including power windows and locks. On this car though, the rear door vent windows are manual, which I've never seen on a power window equipped car. There are no switches in the driver's door for the rear power windows either. I thought that maybe the rear power vent windows had problems, and rather than repair them properly, one of the pervious owners just changed them over to manual vent windows instead, but if that's the case, they must have done a pretty thorough job, and eliminated the rear window switches in the driver's door as well. I plan to pull the trim panels off the rear doors to inspect things, but I'm just wondering if anyone here has ever seen a 4 door power window car, with manual rear door vent windows?

Unlike the older cars where all the power window switches were on the upper door panel on these cars the power vent window swithes are located on the lower door panel behind the remote mirror joystick, if equipped. Can’t say on a Cutlass but it seems like I’ve seen a Chevrolet that had power fronts and manual rear vents but it’s been quite a while
