Got a real shock today when the dealer really said "you better sit down for this repair estimate" -- $$$$ 1700.00 to replace a leakly A/C Evap. core !! Does anyone have any advice to get the price down for fixing a evap. core leak ?? (solder the unit ??, any freon leak fix liquid ?? or ??) Greg Colegrove, '93 100CS, Denver (where it's hot...)
