Heat inside car

heating

#1

92 Buick Reagal. I just don’t get enough heat in the cabin from the vents. It is -2c up hear in Toronto.

The coolant in the resourvou is full/hot.

Any advice will be greatly appreciated. Thanks. Brrrrrrrrrr! John


#2

The first two things to check for. Either an inoperative blend door in the vent system, or a restricted heater core.

I would add “thermostat,” even though you say the coolant is hot.


#4

Another possibility is air trapped in the heater core–especially if the cooling system has been serviced improperly by someone.
