heater does not blow hot air
heater does not blow hot air, engine is warmed up but still no hot air are there vacuum lines running to the charcoal canister?
Charcoal canister is part of the fuel system. You must mean the heater core. How is the level in your cooling system? Is it low? Maybe a thermostat is failed open, hose blocked? Have someone look at your car to determine what exactly is the issue.
