There is a cabin filter that can effect airflow. Napa Auto Parts sells that filter.
You have a blend door that controls heat. That door is controlled by a blend door actuator. Do you automatic temp or manual control?
Not sure what you are trying to do. Please explain better.
Please do not overheat your Integra anymore. Go to www.alldatadiy.com to get a wiring diagram to check the cooling fan operation. Good luck Jim
Angelo2975 is correct. Napa auto parts sells this part at a reasonable price.
I've been told that this is possibly your problem. Customer Concern: HVAC. Has the auto a/c system. The fan is running on high speed at all times. You can turn the control panel completely off and the blower fan is still running on high speed. Tests/Procedures: 1. Check for a voltage signal on the Blue/Yellow wire at the fan control amp . If it has a no voltage, then the fan amp would be bad. If it has a continuous "high" voltage signal, then the control panel may be at fault. For low to medium speed, it should have 2 to 4 volt signal, for high speed, it should be about 9 to 10 volts. Potential Causes: Blower Fan Amplifier
You need to have the codes retrieved from the PCM. Take it to a Napa auto parts store they will do that free. We do!
I've been told that if you continue to drive it the way it is you will harm the catalytic converter.
I agree with Dale45. Napa auto parts has quality auto parts at an affordable price.
