Door problem

[nismobrown]

can anyone identify the following problem.
my 99 gts passenger door started to pop open by itself only when unlocked/
parked or when driven up to the speed where the car locks itself.
this problem changed within a week and now the car can not be opened at all from the outside switch but still unlocks itself but far less than previous .
the inside handle works fine and the doors lock as they should using the remote.

thanks.

Try spraying some WD40 into the door popper button. Then work the button a few tmes. Sometimes the switch gets stuck back there.

I had exactly the same problem on the Skunk. A new microswitch in the door button fixed the problem.

I was hoping that the wd40 would work but unfortunately has made no difference so it looks like a new switch is the only answer.
does anyone know the approx price for the switch?
thanks.
