Leaky core. If your core looks like this – expect windshield slime, fogging and noxious antifreeze odor when you turn on defroster. The fix is to find a radiator shop that will build a new same size - same type core.
Also cleaned main wiring harness connector and junction box. After a number of years on the road, the original GMC factory sealant used in these boxes turns to a gummy tar which can melt down into wiring junction. It’s a good idea to remove this residue, replace it with dielectric grease to prevent future electrical power problems.
*Good article in Avanti magazine-Issue 160 - Fall Winter 2012 that addresses this problem.
