well i have a 1994 3.4 and well the guy before me removed the ac.. but the heater should still work? o.0 and when the heater is on like air is only coming through some of the vents.. and idk why? any suggestions on what to do? 31 degrees is kinda chilly with no heat ya know

 

Is it only coming through the defrost vents? It is possible that the previous owner bypassed the heater core, which would leave you without heat. Or the heater core could just be plugged up with crud and corrosion products.

 

well i fixed it turns out to be a vacumn leak about 10 inches left of the egr valve but now im not freezing
