Drooping outside door handle? Repairs are available. A small broken spring in the hidden latch assembly is the problem.
Probably most were never repaired by prior owners! If requires removing the inner door panel and then the latch assembly. This latch is usually placed in a vise for replacing the small inner spring. Right and left are different.
It is not a difficult procedure, however a big concern is damaging the paint on the large inner door panel. The many small screws must be removed to gain access to the latch.
Good News! Both the right and left side spring have recently been reproduced. They are available from Jim Carter Truck Parts and other full stocking dealers of older GM truck restoration parts.
Good spring in latch
The spring is broken!
Good working spring
