Hello,
It sounds like you have a temperature blend door actuator that is not working here is a guide to show you the steps and the location for your car is below.
Why is my 2007 Suzuki XL7 heater selector knob not delivering heat where I have selected? And today it started blowing nothing but cold air even though the heater was on. Please help me! It's 14 degrees outside.

It sounds like a vacuum issue. Check under the dash for vacuum leaks. If you are lucky, with the engine running, you may hear a hissing sound.

coolant flow is probably too high, caused by a stuck open thermostat.
