Thanks for your question. Sorry you're having car problems, I will do my best to apply my research and supply you with an accurate answer ASAP. It's common for the blend doors to stick and cause this. They are located under the dash in the heater box. This is not normally a job for the DIY, but if you like, I can send you instructions how to do it. Hope this helps you. Thanks, Ron
