Do you really think your situation is that uniqie and that your call or
letter to GM will enlighten them to the problem?  This has been a known
issue for years and years, no recall, no free fix, you gotta pay for it,
like it or not.

chect to see if there was a recall, or if there is a tsb on the lines

If you bought a good extended warratny when you bought your truck, chances
are they would cover this (like the GM Protection Plan). If not, the
warranty was 3 years or 36K miles, whichever was 1st. After that your on
your own, weather it is a wearable part or not makes no diff.

I just bought a uaed 1989 Chevy Caprice Station Wagon.  Every single
door handle is broke.  I felt the same way, and asked a dealer about
it.  He laughed and said the car is old, and what do I expect.  Well,
I just retured an 85 Olds wagon, which is very much the same body, and
has the same engine, etc.  Well, that car is 4 years older and not one
of the handles is broke, or has been replaced since I bought the car
in 1995.  The handles look similar on the outside, but the hinged
parts are very thin on the 89 Caprice compared to that on the Olds.  I
KNOW that these handles were made cheaply, and that is why they broke.
I can honestly say that this SHOULD be replaced by the factory.  At
the same time, I know they wont do it.  Maybe if I hired an attorney
and spent considerable time in the matter they might do something, but
I also know it would cost me more than to just replace them.  The
parts house wants $23 each, so for about $100, and lots of time to rip
the doors apart, I can and will fix it.  I see no other choice.
