I had my V70 serviced a couple of weeks back at my dealer. The passenger side was blowing hot and the driver's side was cold then cool in about 20-30 second swings. My dealer pressurized the A/C system. Now it seems that both sides blow alternately cold then cool in similar 20-30 second periods. This time a different dealer wanted to evac the system and re-check for leaks after my dealer had replaced a hose attached to the condenser. I refused; my dealer today installed a new download related to the A/C. Still have the same problem. Anyone have an idea?
thanks. T
