Dodge Repair - A/C evap failures (both) on 2006 Grand Caravan SXT

Expert: Kevin - 6/24/2009

Question
I brought my 2006 Dodge Grand Caravan SXT in for repair with the A/C blowing warm. (43K miles). $125 later they said they added dye and a pound of Freon and didn't see any leaks but said it must have a leak in the front evaporator ($1200 to repair). I didn't get repaired but it worked well for about 2 weeks. (I felt it may have been just low freon level rather than a real leak)

The first day the temp hit 95, I started the car. It idled for a minute or two and I heard strange hissing sound. At the back, a very large bright green puddle of dye and oil (about 2 foot circle) appeared and the AC had stopped working.   I brought in and now they said AH HA, We found the leak. It will now cost over $2000 to repair.

It appears to me that they packed the system with too much dye and oil and, for some unknown reason, no safety valves worked and over pressure blue the seals.

Is there some other explanation on how both the front and the back evaporators would suddenly develop a catastrophic leak shortly after being checked out by the AC experts?

Is it likely that both evaporators failed at the same time, without some "help"?

Are there seals that could have blown due to overpressure that can be more easily (and cheaply) replaced than all the parts?

Thanks

Answer
freon is a gas   its in a sealed system if there is no leak there would not be a reason to charge it up if they had to add some in with dye there is a leak.
Evap as in the dash or the condenser under the hood?

I see condensers more then an evap I have only replaced one evap int eh dash and about 100 condensers   look at the lower left hand side of the condenser it will look wet if leaking that's where they leak most of the time.
