Default AC From Hell

So.. I've been dealing with AC issues all summer.

It started as just not cooling very well and I got a new switch and compressor. Then it was just cooling whenever it felt the urge and not cooling whenever it felt like it (switch on or not!) so I got a new AC control module. Then it was back to not cooling very well and had a leak up near where it goes into the inside of the dash and whatever so I got a new gasket. Now it's back to not cooling and the mechanic says it is leaking inside the dash and needs a new evaporator. He said he put dye in it and the dye is leaking out the drain tube and he does not see a leak anywhere else.

To get in to the dash and replace that piece he quoted me $700. While I know that's not a bad price when compared to other places, I can't really spend another $700 after just spending $600 on the compressor.

Here's my dilemma....
Do I get in the dash myself and replace the damn piece? I don't mind getting dirty, just need some guidance.

Or do I say screw it and ride around hot in Florida summer after spending $600?

Or do I suck it up and pay the $700 that I really don't have? Which means it would probably be on credit... ugh


Does anyone have experience getting to this piece? Is it something that can be accomplished with patience or am I going to need 1000 tools I don't have? Is there a walk through somewhere?

it would be $50+ shipping for the part, and around $70 to have the AC lines vacuumed and refilled, plus a gallon of your preferred coolant to top off the radiator after you reinstall everything. figure on spending around 150 for all that.

the whole dash comes out to get to it. is it worth saving 550 to remove the dash and change it yourself? is this a job YOU think you can tackle?

This is the hot topic.... I would totally do the work to save the $550. I think I could do the work, but not knowing for sure and not knowing the parts well makes me wonder if it's a good idea. Living in Florida and not having the $700 makes me think it is a good idea. lol

I don't know... driving the car off a bridge might be a better option at this point.
