Help!! my ac starts making a grinding/clicking noise. I have to put it to hot temp to make it go away and then after a while I can lower the temperature. Can anyone help me to figure this out so I can fix it. Please and thank you.

 

One of the servos behind the glovebox needs to be replaced.

 

Do you know by chance how to tell which one?

 

I've forgotten but if you do a search on the Gen1 forum you should find several threads on the subject.

 

search for mode and mix servo replacement

 

Mix servo responds to Cabin temperature [hot/cold] while the Mode servo directs air to various vents. In Auto mode the vents keep adjusting the flow of air [you can get out of the auto Mode and step through various air flow pattern by operating the Mode ****. This should help you diagnose what is going on.
