Passenger window issue.

1. When lowering top both windows lower.
2. Drivers side nor passenger side switch will raise passenger window or lower it.
3. After lowering top with passenger window in down position you can toggle the child lock to "ON" and the passenger window will go up

Any help would be greatly appreciated to figure this out. Thanks ahead of time for the help!!

 

Just to clarify:
when you switch the child lock switch(referred to in the manual as the "Main Switch to ON, the window goes up
without also needing to operate the passenger window up/down switch?
If you just leave the main switch in the ON position, what happens when you lower the top?

 

Yes you are correct. The switch that has the word "ON" stamped on it. Passenger window will not work with drivers window switch or passenger switch. Passenger window WILL go down when you drop the top.
When the passenger window is down you can get it back up only by flipping on the child lock switch. Its the craziest thing I have seen....lol

 

It looks from the wiring diagram that signals from the switches pass through the power window control unit and convertible top
control unit, so alas nothing is simple.
Here's a scenario consistent with the symptoms, without actually knowing the failure mode for the switches/window regulators
or the control unit behavior, so it may not be realistic at all:Again, a WAG.
The Service Manual has diagnostic tests, but they're not simple.

 

I'm guessing, like "Oth." that one of the switches that controls the passenger side window is shorted or otherwise stuck in the Up position. The Main Switch controls power to those two passenger widow switches. Several dozen cycles of both switches in both up and down directions has a remote chance of correcting this and costs nothing to try. Otherwise you're gonna need to access the switches and test them for continuity. I'm guessing the switches are standard Honda parts from that era so a bad switch shouldn't be expensive.

See pages 120 - 120.1 of the S2000 Wiring Manual for the switch wiring.

Thank you both for the ideas! I currently have the passenger side door apart so I can get to everything.
I think I will try to find the passenger switch and replace it to see what happens. I will let you know how it goes!

 

Instead of shot gunning parts,or getting out a meter to check continuity that is probably a stretch for most diyer's, what if you merely unplug the passenger side window switch and see if things work then.

Like if the switch on drivers side that is still plugged in can now operate the passenger window like it should. Then you'd confirm the diagnosis from Oth, and you'd know that was the fix.

Or you'd know at least that switch isn't the issue, and not have to waste money and time buying that one. The diagnosis from Oth might still be correct, just affecting the switch on drivers side.

Can't recall if you can unplug that switch independently of all the other controls on drivers side, to repeat same test buy opposite door. Plug passenger switch back in, unplug drivers side switch that can control passenger window, see if passenger switch now works like it should.

 

So I did a test.

Hold passenger switch up, simulating a switch failed in mode suggested by Oth. Switch always trying to put window up.

In this scenario, I can reproduce pretty much all your symptoms. The only thing of note is I can still hear relay clicking in passenger footwell area when I try to operate the drivers side window switch (that controls passenger side) down.

No window movement occurs. But I can hear that relay. When I operate the drovers switch up, while window is already up and passenger switch simulating stuck up, no relay click.

No relay clicks no matter what if the on/off switch is off.

If I swap which switch is simulating failed, hold drivers side switch (for passenger window) up, then its all the same symptoms, just roles reversed.

So, do you hear any relay clicks when trying to use either switch to make window go down (with on/off switch on)?

If so, whichever side gets a click, that switch is good. Whichever side does not elicit a click, that is the side with the switch failed in mode Oth originally suggested.

 

OK Car Analogy I had previously tried running the window up or down without the passenger switch and nothing happens. I read somewhere that
everything must be plugged up to complete all circuits or it will not work. On the other test you walked me through I tried that also. The passenger switch WILL
make the relay click behind the panel but the passenger window switch on the drivers side will not make the relay click in ANY position or configuration.
So I am assuming I need to get the drivers side switch cluster and replace it? Thanks for everyones help by the way. You have been awesome!

 

Concur, switch failure on drivers side, failure mode like Oth suggested.
