Thanks, I see the spring over the post on the right side of that Pic. I'm missing that one on my drivers door. But they have two spring listed one called the push knob return spring, not the coil in the actual outside handle, but that one in the pic. They also have one called a door latch spring. Different part number than the one in the pic. The latch spring is available from suppliers here but the push knob return spring isn't. I have pics of the latch in my door, one can see there is no spring like the pick but I also see another spring that looks similar attached to another part of the latch. Unless it's the missing one that broke and is resting in another part of the latch. Don't want to take it out if that spring is supposed to be there and I just have to replace the knob return spring.
I have a pic of the latch with the spring in pic you posted missing, #11 and a pick or another spring in the latch in pic #21 lower left hand corner of the pic.
