Why does the heater blow in the passenger compartment?
Why does the heater blow in the passenger compartment?
If they are even slightly open, or not well sealed, warm air will pass into the passenger compartment, even if you have your heater control set on Cold and the fan on Off. Many cars pressurize the passenger compartment by having the fan blow even when set on Off.
Why does the AC only work in the passenger compartment?
This helps prevent exhaust gases from entering the passenger compartment… but may mean that air that has passed through the warm heater core is being sent into the passenger compartment. Your dealer may be right: only using the AC will overcome the ingress of heat.
Where does the hot air come from in a car?
However, the hot air doesn’t just come from the passenger side, it comes from the driver’s side as well. And from the dashboard vents. When I turn on the defrost, I can hear the vent doors locking, and soon the hot air stops. This is bad especially when the weather is hot outside.
Why does my car have a fan on all the time?
The hot air feels like it’s the engine’s hot air passing through in the off mode. Relying on a electric fan to keep exaust gases out of the passenger compartment sounds very shortsighted. I’ve heard of some GM cars doing this (fan always on), but I’m not aware of any Ford cars that do.
Why are the vents on the passenger side warm?
Repairs for this problem = A/C compressor, orifice tube and drier replaced about 1 year ago. The problem I have is that when you turn the ac on the cool air only comes out the 2 vents on the passenger side. The 2 vents on the drivers side have warm air blowing out. A/C is controls are set to max air and max cold on the temp control.
Why are the vents only blowing hot air?
Passenger side front vents only was blowing super hot air, no matter what temp we selected on passenger side. This appears to be a very common problem, with a few different causes.
Why does my a / C vents blow cold but warm drivers?
It will not be apparent if just looking at freon gauge pressures- they will be normal. But a system that is 1/2 pound low will cause the passenger side vents to blow cool or cold air, and the drivers side to be less cool or even warm on this car. There is simply not enough freon capacity in the system to cool the air to the drivers side.
Why does the passenger side blow high heat?
The driver side will blow cool air or AC, but the passenger and rear blow high heat no matter what the setting. We brought it back to the dealer and he said it was the dials that were broken. We believed that because the rear dial just spun freely. They replaced the whole interface and it worked for a short time.
