My 2002 EXL Odyssey (54K) has recently (within the last 2 months) started to make a noise on the front passenger side dash that can best be described as a clicking or AC port trying repeatedly to close but not closing. We always run the AC in FULL AUTO mode so as you know, the system adjusts the fan speed and flow of the AC through the different AC zones (feet, dash, feet & dash, and so on). To make a long story short, when the system makes these adjustments, certain valves close (when the air is being redirected), and the sound is almost like those redirections (or port closings/openings) are struggling and not fully setting. So, we continuously hear what I call reattempts at port closings (redirections) and it's about to drive me over the edge (these occur every second). I took it to the dealer today, and I guess they didn't feel like looking at it because they said they couldn't recreate the noise.
Has anyone experienced these noises and what can be done to stop it. Thanks for your time.
