I had the same problem and found that this is caused by the Dual heater Control Valve malfunctioning.

The DHCV can be purchased at Rock Auto Parts for around 150.00 and can be replaced in around 30 minutes. This valve controls the hot water flow for the heater core for each side of the passenger compartment and when it fails, it's default is "open" which allows the hot water to flow freeley for whatever side failed. It is located on the passenger side front about 6 inches down from the top of the radiator. You will need some patience and some mechanical skill to replace it but its not terrible.

Check:
1)
fuses
2)
cables behind the a/c control cover

Two things I would do.

Heater blowing hot air on the passenger side and cold air on drivers side what is the problem please


There is a flap inside the vent. It is controlled by a vacuum controlled actuator. Either the flap is stuck in one position, or the the actuator is faulty. Check vacuum lines to actuator.

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.
