A/C Evaporator core?

Has anyone ever replaced the evaporator core on a 360? Mine has a freon leak. I can't find anything on it. Do you have to take the dash out? Will it come out from under the dash?
Thanks for any knowledge or experience on this.

 

OK, well, I'm a little depressed. I don't have the shop manual. The idea of pulling out the dash is not what I want to think about. I've had the car 3 different shops for the diagnosis. First shop did the dye and couldn't find the leak. Second shop, (specialize in Ferrari, Lambo, Aston) same thing, couldn't find it and suggested it may be the condenser. I just changed the condenser and took it to the third shop to refill the freon and check for any leaks. This guy uses some kind of sniffer to detect freon. Found small leak on the pressure switch and one Shrader valve but a bigger leak from the evaporator. I believe he went up through the drain tube. This evaporator is off center towards the passenger side so I thought it may come out with battery and glove box removed. I've changed a few dashes in Porsches and not the tough, just lots of screws to find. But that seems like only half the job.
I'll call the Ferrari shop to see what they charge otherwise, sell, as/is.
Thanks for the comments and info.

So, I'm pretty sure I won't try to replace the evap myself. If I were younger, then I would tackle anything. Restored a handful of old 911s. I'll check with the shop to see what they would charge. But, yea, breaking plastic parts makes a lot of sense. I removed the front bumper and found one or two broken vent attaching points. I guess after 20+ years, the plastic gets brittle.

I'll check with the shop tomorrow about what parts they sniffed. We'll be at the shop next door getting our Cayenne programed. But he did mention that he would sniff the drain and vents. When he said the evap was the biggest leak, he didn't say how he came to that conclusion.

Thanks for the responses, really helped me decide how to move forward.

 

Wow! 25 hours of labor. I'm out. I've been to Salerno's but only for an estimate for a clutch. There was a 4 to 6 week wait, I believe then he had a back or leg issue, so they told me to try Stewert's in Sac. Got it in a just a few days and a better price. I have a belt service planned at Stewert's but may wait till spring when the A/C is more critical. I've taken out 911 dash's and it looks nothing like your photo with wires everywhere.

I did find out, today, that the shop says that sniffing the end of the drain tube works pretty well. Since Freon is heavier than air and it will come out the bottom. The vents, he says, is if all else fails. Also talked the German shop next door. He says, evaps are common to rot since they produce a lot of condensation and if the drain is blocked, then there's the problem. Especially in hot humid areas.
So, for now, the a/c repair is on hold while the weather is cold. Just need a few days of sun and no rain.
Thanks for all the great responses. Not what I was hoping for but what I needed to see.

Yes, I will get the timing belts done soon and check on the price. We've got 8 cars so will prioritize what is important to do first.
Thanks for all the support, Bob
