Sounds like the switch broke (the one that directs the air valve) or disconnected somewhere along the shaft.
It have battery
it works off of vacuum. check the lines coming from the vac pump under the hood for dry rot or cracks
Could be a vacuum problem--either broken or disconnected hose or bad vacuum motor under dash or coming in through firewall Defrost is the default position for this system
the heater core is going out
The most common thing will be that you have a leaking heater core...........
That is condensation and it is normal for water to come out of an air conditioner in the back of it.
usually you will get antifreeze smell and steam inside coming from defrost
A smell coming from a reverse cycle air conditioner may be a signal that the filter needs to be cleaned. A smell like engine exhaust might be present if the air conditioner motor is in need of repair.
I get hot air coming out of my air conditioner on the passenger side, while I get cold air coming out the drivers side. Can you tell me why and how do I find the schematic to fix it?
The air conditioner is low on refrigerant.
You may need to replace the power control module.
You need to have the faults in the transmission read.
