Hi. Yesterday my passenger was able to lower the window but could not make it go up again. Using the driver side switches nothing happens, neither up nor down, only the down on passenger side works. I looked at the fuse panel under hood. Could not see any numbers on there but the two 20 amps fuses relevant to power windows looked fine. When lowering the window no weird noises can be heard. Sounds electrical issue to me... No?
Is removing passenger side inner door now my only option?
If your NSX is a '91-93, and you've never had the window regulators upgraded with the "fix-it thingies", it's possible the clip in the window regulator broke. Read about it at:
Power Windows
If that's what happened, you're probably going to be buying a new regulator for the passenger side.
If the driver side hasn't been upgraded with a fix-it thingie yet, you're going to want to at least get one for that side, to prevent it from happening on that side too. You can buy them here.
Hello Mike. Thank you for your help. I pulled the driver side switch thinking its the bad one since it's being used most and also the one which doesn't go neither up or down. But continuity checks per service manual for passenger window up and down checks ok. Anything else I need to check before putting everything back together and moving to the passenger side switch?
I would leave the driver switch out until you find the problem just in case it needs to be removed again but it needs to be plugged to the harness. Put some plastic around the switch to keep from scratching the switch panel and move to the other side. If you already put the driver switch back then leave it for now.
If the passenger switch tests good per the service manual then leave it out also because we have a couple more tests to do.

Yup. Sometimes there can be a little bit of corrosion inside the connectors, enough to cause a problem; you disconnect and reconnect, and it scrapes off the spot where there was no connection. Glad to hear it's working now!That's great news! Sounds like it was a bad connection.
