Although the thaw is overl and heat is nice, enough is enough. Even with my climate control set on lo on my 90V8, heat pours though the A/C outlets. The proportioning valve going from heater to A/C outlets seems to be ok by going from HI to LO, but all I get is extreme heat from all outlets including the defroster. Help, please!
