Evaporator diagnoses.

The wife has had dye put into her 2000 Dodge Grand Caravan A/C twice at 2 different shops but neither one can find the leak.

I have the time to pull the dash but how can I know for sure that the evap. is the problem?

Thanks for any help.

Most of the time, if you can't find anything else leaking, the evaporator is probably leaking. Have them check for dye at the a/c drain.

that year has an evap probe if I not mistaken...you can inspect it from there

oops, double post, disregard

Thanks for your replies.

hundahunta, can you elaborate on the evap probe method? I have the factory service manual for the vehicle. I see I'll need to remove the glove box, disconnect the probe & remove the evap probe grommet. This looks like it will expose a portion of the evap. Am I just looking for any signs of moisture on the exposed evap?

Thanks again.

you usually look for oil on the coil..and dust and debris stuck in that area...if they installed dye usually a uv or black light will expose the leak..
