Having problems with your 1998 Chevrolet Blazer ?
Water leaking coming down over four wheel drive unit
The condensation from the ac canister there is a little spout that comes out of the fire wall and when you use your ac or defrost the ac compresser will kick in to take out the moister in the air when using the defrost setting, the water or condensation that builds on the inside will drain out of the spout and thats probly what your seeing either that or u have a bad heater core.
