Just recently whenever i use my A/C or Heater there will be a clicking noise of some sort behind my steering wheel area, the noise will get louder if i turn up the fan speeds. It still blows both hot and cold air correctly as it should. What would the noise be, and should i worry?
Sounds like a piece of junk has found its way into the AC system and it is lightly hitting the fan. A mechanic may be able to look in with and endoscope and may be able to extract it without too much work.
