If your 2007 Vectra's heater is blowing cold air, it could be due to several reasons. Common causes include low coolant levels, a malfunctioning thermostat, or a clogged heater core. Additionally, a faulty heater control valve or issues with the climate control system may also prevent the heater from functioning properly. It's advisable to check coolant levels first and then have a mechanic diagnose any potential issues.
Same problem vectra heater only blowing cold checked water coolant and it was empty. Topped up now blowing hot just hope I not got head gasket probe

It was so cold that he had all the heaters on in the house.
Call a heating specialist. Heaters are too dangerous for amateurs to fool with. There is danger of fire and, in the case of gas, asphyxiation if they are not properly repaired and adjusted.
Obviously you have a cold if you are constantly blowing or you have something spicy or you are crying
