joyjrn3 Posted June 25, 2010 Share Posted June 25, 2010 i have a 1999 gs400 with a nav. touch screen with 92k. when i turn the ac on it blow very cold but after a few moment the ac slows down and stops and cuts off then comes back on about 30 seconds later. the mechanic said i need a new head unit(new touch screen). but my radio and nav system works and other functions work fine. my guess was to change the factory air relay. thank you for any advice.
