heater help

[whojohnjones]

I'm trying to get my heater in working order
before winter kicks in and I have a few
questions.. I have a 1983 Buick park avenue with Chevy 350 with 350 transmission. what does the vacuum ball connect
to?(th350 has manifold vacuum) I have new
heater core and the heat from the floor isn't
very hot. is there a different part I'm missing?

Need more information.......is your engine getting hot(check thermostat)....is your trap door working for cool to heater.......do you hear vacuum as you move the control from defrost to heater to bi-level to vent

let us know

yes the trap door moves but the heat isn't very hot and I can't figure the vacuum lines

hey

so is your engine getting hot(normal operating temp) about 195 degrees farenheight? do you have a temp light or actual guage? after its been running for 30 minutes--- is the top radiator hose (large) hot?

192 degrees constantly

sound like the trap door is not going to full heat--- locate it and watch it as you adjust it from cold to hot then see if it can go further in travel---probably a vacuum line cracked---check every little hose---and grab a six pack....you will be there awhile lol
