Have a 2002 Chevy Venture, condenser was replaced in 2007 because of leak [Marks Air in Tampa FL] and has been working great until now. AC works great at low speeds, 55 or less, but at 70+ will cycle between cold and ambient temperature at both front and rear vents. Tempature cycles more the faster you attempt to drive or when the engine downshifts into third to climb hills. Investigated after long highway drive and found both fans running at high speed but the low pressure/return line was NOT cold and did NOT have water condensing on it so IÃ¢ÂÂm thinking it has a new leak/low on R-143a. Currently moving so doesnÃ¢ÂÂt have access too much more then hand tools.
P.S. Marks Air provided great service when I lived in FL.
