Oldsmobile Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.The most common cause for the type of problem you are having is in most cases caused by a failed Temperature Door Actuator. Try swapping the passenger and driver's temperature actuators and see what the system does then. When doing so make sure to mount them, do not leave them hanging.
