Still chasing heater problem
I have my heater problem almost solved.
88 Bonneville SSE. with ACC (automatic climate control)
I have all new hoses, Stat & both stat seals, flushed heater core and inspected ( it'* clean as a whistle with excellent flow), radiator is perfect, I have no coolant leaks, and all hoses are hot to the touch. My infra red thermometer reveals upper hose to be 175 -180 degrees + when up to temperature. Gage on dash go'* a tad higher than the first line.
Problem I still have is when the blower is on full high the temperature blows not so hot. If I turn the blower bown down just one notch the heat is much hotter. Also with the blower on full high it still seems like it should blow more air. Like the air is just not coming out like it should when on full high. I have verified the temperature valve works properly.
One thing I noticed was this:
The melted goo. Seems to be an air leak, however not that much of one.
Anyone ever seen this molton putty. It'* the sealer that is used around the evaperator core where the tube exits the box. I keep resealing it but it keeps melting back down. I did remove the ac accumulator as the ac does not work and it was in my way when I changed the heater hoses. I know it is hot enough but I'm scratching my head on this one.
I'm thinking I need to look into the vacuum actuators for a possible problem. Or maybe a linkage problem for the valves.
Any Ideas?
