I have a 2006 quad cab Mitsubishi Raider. I get a clicking noise from underneath the dash sounds like it's coming from the passenger side when my heater is turned off for air conditioner it doesn't matter temperature wise. I'm assuming I've got an actuator going out. I'm also assuming I have more than one actuator. which one do you think it could possibly be? thank you

You are most likely correct that this is an actuator. However, we are going to have to identify which one.

The easiest way to do that is to access them and get the clicking to start and touch each one of them to find out which one it is.

Accessing them is pretty much the same process but here is a guide that will help with more general info:

Once you access them, you will know which the issue is. The most common one is a blend door issue so I attached the location of all of them but the process for the blend door.

Please run through the info below and let us know what you find. Thanks
