OT '92 Ford Tempo lock problem

[gr8hunter1 at comcast.net (Jacob)]

Just a guess: when list is down any mail sent to it dies. Going with 
that assumption (spelling?) im sending this again.

Im hoping that power locks are all pretty much the same and that u guys 
can help.
Short version.
One door on my ford tempo will not unlock. i put wd40 any where that 
made sense and that didnt work. what do i do now.

Long winded cersion.
My parents got me (and my brother when he can drive) a starter car. 
Basicly a car for us to get where we need until we can afford our own.
The problem: (besideds the fact that its a ford tempo gl, ack...) the 
back passanger door simply will not unlock. the little pull up thingy is 
broken off almost to the visible base so that only a cm or 2 are 
sticking above the door panel. So i cant unlock it manualy. The real 
problem is that the power locks wont unlock it (only the one door, all 
other doors will unlock manualy and via power).
So I took the panel of in hopes that it was visibly jamed only to find 
out that its really hard to see the actual latch, but I can the the 
little motor that should operate it by the powere switch. I posted on 
diynet.com to avoid asking a scirocco group about a ford, they said to 
put some wd40 on all joints and wait a while and it should work. It 
didn't. Basicly... WHAT DO I DO?
