I am getting a loud electronic buzzing sound from my 2000 EX sounds like it is coming from the climate control unit in the dash. I did the DTC check and get 88 followed by a _ so looks like no code. The fan changes speeds throughout the range just fine. I only get hot (very hot) air. I have noticed that the buzzing stops if I turn the temperature control to full hot anything else I get the buzzing back. It seems that it can not move what ever flap or valve mixes the air and allows the cool air into the system. What should I look at?

I re posted this on its own as it was buried in a related but different thread, sorry if I broke any rules!

Thanks. I am very close, on mine the blue plastic tube moves with the cable each time, for now I set it to cool air in the cabin manually. I couldn't free the cable only the whole assembly moves so I might just need to work it more or... I may actually need a cable. Does anyone know what the inside access is like? I imagine it is awful.
