Clicking behind the passenger dash
There is a clicking in the passenger side dash
when the heat is on. And it sometimes does it
when you shut the car off
Probably a bad blend door actuator.
Thats exactly what it is is the a/c and heat actuator. Take glove box out and its kind of hqrd to get to but its in the upper back you can turn on the car and crank ac or heat while doing this to locate this actuator. Ive had to replace two now and thats what starts happening when its going out is the clicking in the dash.
