This seems kind of weird to me so I wanted to see if it was normal.
The car, from the vents only expels heated air on the right side of the vehicle. It is quite hot on the passneger side (that is to say most people would not want it to be blowing directly on them for too long) in the middle console the passenger vent is noticably warmer than the drivers center vent. The drivers side door vent is cool or slightly warmed over at 18* outside temp with the engine @ operating temp.
I replaced the cabin air filter
I checked the valve coming into the firewall, it appears to be operational
I topped off the coolant, it was slightly low at the reservoir and full at the radiator
Both lines into the firewall get warm, the upper is warmer than the lower return line
If I close the warmest vent, the others do not get noticably warmer, If I close the coolest vent, the others don't get noticably cooler
The vehicle temp gauge appearls to be operating normally, which leads me to assume the cooling system is working as it should (thermostat, etc.)
If i turn on recirc, there is a noticable improvement in the amount of heat output
My ask is this - could there be a vent or something that is opened, stuck, clogged etc. that shouldn't be? I know it's cold out - however it is quite surprising just how much the heated air is able to cool down from the right side of the vehicle to the left. Is there something I haven't thought of?
