Что за глюк климата с тиканием?
Управление актуатором пытается поймать нужную позицию и постоянно крутит туда-сюда. Под приборкой тикает и актуатор дохнет. Замена помогает условно. Новый так же по тем же причинам сдохнет.

Cause
This condition may be caused by the Heating, Ventilation and Air Conditioning (HVAC) actuators that may hunt for the correct commanded
Correction
Technicians are to perform the normal diagnostic procedures in SI for these concerns. If diagnostics show that the HVAC system door(s) travel
below 5 counts (out of the lower range) or above 250 counts (out of the upper range), then update the software calibrations in the HVAC control
module. The new calibrations were made available to dealerships as part of TIS2000 incremental satellite update version 2.5, which was broadcast to
dealers in February 2006.
