Are you sure you have the right number... it doesn't show any matches for me.

I looked at your old posts and searched for bulletns for an 06 (assuming that is the car you are talking about) and I think I found it. Does this sound like your issue:

"LZE, LZ4, LZ9 Ticking or Clicking Noise Heard Inside Vehicle on Passenger Side at Idle (Install Updated Heater Inlet and Outlet Coolant Hoses/Pipes) #06-06-02-002C - (08/24/2006)

Some customers may comment on a ticking or clicking noise heard inside the vehicle on the passenger side. The noise may be noticeable with the engine on and at idle, with the vehicle in PARK, and with the HVAC and radio off.

The noise may be caused by normal EVAP purge valve operation. The EVAP purge valve operation may be internally grounding out, creating a noise path through the coolant inlet and outlet hoses/pipes."


Then it just goes through the steps to replace the hoses. Hope that helps.

Thank you. Yes that is it. Question though. How did you find the info? I searched all over the internet for it.

Thanks again!!
