Q: Blend doors not working properly.

asked by on

I have cold air blowing out the driver's side, and hot air blowing out the passenger's side. I am assuming that either the left or right blend door is not working properly.

Thank you for your inquiry. Your assumptions are very close, especially if your vehicle has a dual-zone system where the driver and passenger can enjoy different temperatures. Have a certified mechanic, like the ones at YourMechanic, inspect the system and perform the appropriate repairs.
