Not the compressor, but the evaporator thing

(1990 Plymouth Voyager)
in Alexandria, VA on August 09, 2010
$570 later tells me it's not the compressor but the evaporator, the dashboard has to be pulled, and the guesstimate is $1200. Female owner.
He is also charging me $480 to replace the transmission speed sensors so the car will stop acting like a TOON car in Who Framed Roger Rabbit. Am I being taken here? Would the dealer charge the same or more? Thank you.

The dealer would charge more and as for the AC compressor if it wasn't in operating condition then they couldn't tell the evaporator had a leak until the compressor has been changed and the system filled will freon and tested.

Thanks! They've done the leak test (3 doses of R12, vanished) and the choice is between sealant $300, might wreck the whole a/c or it might work, and the evaporator at $1200 but it will work. This is a wheelchair-adapted van, not easy to just drop and replace. Thanks for your sound advice.

See if they can convert your R12 to R134a while they are working on it as its cheaper than the R12 and easier to service later down the road as everyone carries that now

Ohh. I just looked at the invoice for the leak test a/c service. That is R134a that they used, 3 at $75 each. In the beginning of this, when we were talking about compressors, there was some mention of retrofitting but it was decided against because the present system uses mineral oil, raising issues of compatibility and seizing up. I assume that issue won't come up again.

The ride home this evening, while much smoother with the transmission speed sensors replaced, was still boiling hot. So the a/c just has to be repaired. Thanks for the recommendation!
