Can a Subaru Forester heater work when the air conditioner is not blowing?
It is entirely possible for your Forester’s heater to work just fine even when the air conditioner is not blowing cold at all. That’s why troubleshooting the air conditioner is totally different than troubleshooting the heater.
Why is my air conditioner not working in my Forester?
Blower Motor – If there is no air blowing from your Forester at all, the blower motor is at fault. They are not that expensive and are easy to replace (most of the time). Blend Door – The blend door controls how much air conditioned and heated air enters the cabin.
What does the thermostat on a Subaru Forester do?
The job of your Forester’s thermostat is to regulate the temperature of the engine. It does this by allowing water to enter the engine when it is getting hot, and by keeping coolant from entering while the vehicle warms up. Sometimes when a thermostat goes bad, it stays stuck open.
What does it mean when your car heater is not working?
There are two hoses coming to and from the heater core. They both should feel warm or hot to the touch with the engine on. If one of the hoses is hot, and the other one is cold, that is a pretty good indication that the heater core is clogged. If the neither hose has any heat, you may have air in the cooling system, low fluid, or low pressure.
