Did it on an 87 5ktq, but I don't think it's that much different from the 
later body type.

First thing I did was to try to clear the drain hole by the rear pillar from 
the top. I tried to snake a line from the sun roof to the pillar drain along 
the trough and then from the rear passenger light fixture. This was pretty 
frustrating and I don't know how much it cleared. I also went to the local 
shop and they were kind enough to let me use their air compressor and a line 
as a snake. That's what I used to clear the drain on top. From the bottom 
drain in the rear wheel well I tried to snake a line up that drain but 
because of the way the line turned it was impossible to get a line to go up 
more than a foot or so. I wound up taking the trunk lining out, disconnecting 
the rubber drain hose and snaking the line up the rear pillar. 

As I said this procedure worked for the 87 5ktq and I don't know how much is 
applicable to the later body style, C4??.
