I have a '93 manual transmission Subaru Impreza with approximately 90,000 miles.
The vents constantly blow hot air even when all the settings are turned to off. It blows hot air when the a/c is turned on. I don't need to have the a/c working but I would prefer NOT to have hot air blowing on me constantly.
I have had various repairs done including having the clutch replaced, an oil leak sealed, the water pump replaced.
