In-Car Temperature Fluctuates Regularly and Slowly Up and Down.

Cause/remedy:
a) Air let nozzle not operating correctly or pinched or not connected hose on in-car sensor, air let nozzle or front wall pillar.







Check connection of in-car temperature sensor ventilation, air let nozzle and hose. If hose is correctly installed and connected, check whether residual glue inside hose (damping member) obstructs passage (arrow).







Perform smoke test for checking air let nozzle. Smoke must be attracted through grille at in-car sensor. If air flows out through grille, exchange air let nozzle (47).
