defrost only

[nvrhapy]

my heater control is stuck on defrost only i assume this is due to a vacuum hose leak? where would i look to find the leak? or how would i go about finding it?

yeah your not gettin a strong vacum so the defrost is the default setting have you tried looking at your lines yet. alot of times a vacuum hose will just pop off the fitting. its kinda hard to pinpoint where its coming from it took me awhile just looking under my hood for the leak
