There is a drain under the hood on the passanger side of the firewall. It is either a hole in the evaporator case or just a raised place that has stopped up. Use a rounded tipped instrument to unclog it because the evaporator is about one inch above the case and can be damaged with a sharp pointed object.
I have seen the doors with inches of water inside because the drains were plugged up. You could hear the water sloshing back and forth while driving.
If a 1996 Bravada will turn over, but not start, the carburetor may be plugged. Bad spark plugs, a clogged fuel filter, or a clogged air filter can also be the problem.
Condensate drain plugged or disconnected
Might be air in the heater coreCheck coolant levelHeater may be airboundevaporator drain may be plugged
If the problem is that the air never gets warm, it's most likely a stuck-open thermostat. If not that, heater core may be plugged.
Most likely the external drain (in front of the firewall) is plugged.
you shouldn't have to, there should be a line running from the main reservoir through lord knows where to reach it. so if it's plugged or cracked.... well.
The most common cause of an air conditioner not blowing air is a plugged filter. Be sure your filter is clean.
Two possibilities:There is an air pocket in the heater core caused by low coolant, the 4.7 V8 is prone to loosing coolant and not having a visible leak.The Air conditioning drain is plugged and there is a bunch of water in there sloshing back and forth
Could be, Low on coolant, A stuck open thermostat, A plugged heater core, A faulty temp blend door actuator,
I usually leave it plugged in if I can, because why not keep your battery charged?
because its not plugged in
