SOURCE: Fully warmed up; blowing hot and cold; Suzuki XL-7

Its just a vent damper plate not operating, it's like a gate which controls the flow of air,,usually they are operated by vacuum, or cables.
Service center time, unless you are handy with your own repairs.

Why does the front heater only blow cold air


you must listen when changing the temperature from cold to hot to see if you can hear the heater duct opening & closing,if not could be a vacuum hose is disconnected or broken,or the vacuum motor that moves the duct door has broken you might hear a hissing sound,or a cable has broken,I don't think it's a fuse ,because it's working when you turn it on,those are good possible causes I have given you have fun & I hope you have small hands,limited space acess

Troubleshooting for a 1998 park avenue


White smoke usually means water in the cylinders. I would say you have blown head gasket or intake manifold gasket. Could be something cracked or something I don't know about. Unless it is something I don't know about will not be simple or cheap to fix.
