My first Subaru and my first post.... '98 Outback. I had the sticky heater button(s) problem when the temperature outside got cold. After pulling out and taking apart the climate control unit i found that the prior owner drank coffee with allot of sticky sugar. the darn cup holders are not in the best of places. My issue Now is after i put things back together the heater slider knob (controls the cable to the white actuator by the passengers feet) will slide on its own. push to the far right (hot) and it will slowly creep to the left/cold. I have tried and tried to adjust the cable but it still moves on its own. ??? thoughts ?
