my 98 doesent have the auto down feature on the passenger side and the lock button is flat unlike the one in the pictureWell I think they are both have this switch.
Thats what i was thinking, thanks for the inputi know the '99 (i think it is) drivers side is not compatible with the '98 and older. I tried so I could get the 2 front auto down instead of just the one. I bought it and was not PnP. So I would assume the passenger side is also not PnP.
