2004 Prius with an A/C leak that they cannot find. I have had a slow leak in the system now for 2 years and everytime they recharge it and put tracer dye in it, they never find the leak ($225.00!) this lat time I was able to get them to commit to removing the dash next time it leaks out to check the evap cooler. Any thoughts? Frustrated in Arizona...it's a dry hate, I mean heat, state!
Maybe they're happy not finding it... Try another dealer. If you go to an independent shop make sure that they know that they *must* use only Toyota's non-conductive refrigerant oil, otherwise the compressor will be destroyed.
