Once you do the Evap, everything else is bolt on/ off and you don’t lose the car use during the work, unless it’s the compressor (needed for SERP belt)
Well, abscate, you're forgetting the silly hand contortion you have to accomplish to attach lines to the compressor... :lol: (My god that took hours... I can only imagine what it's like for you Turbo guys!!!)

I really should get up there and do this A/C job already. (I really think I need to pony up for a new compressor...)

Best to do that A/C work before winter as you may need functioning A/C to clear the windows in damp cold weather.
Sigh... you're right. E. I'm pricing parts on Rockauto right now: Approx $150 for Four Seasons Evaporator and Drier and an APDI/PRO Condenser...

FCP is my go to because :1) they sponsor this site and 2) have lifetime replacement warranty. The latter is not likely to be so much of a factor with a/c hard parts (probably a job you'll only do once).

See if my 1998 parts will fit your 99 Marco. Can trade my engine picker rental for parts.

My vacuum leak was at one of the hard lines into the drier. Hadn't managed to get it seated all the way. Mechanic found it. I never would have.

I’ve found you can crack and tighten these with about 30 inches of extender over near the end of the motor.

Use a brand new sharp good quality tooL ( hex or Torx to fit), smack end with hammer 5x to seat , and crack the fastener. Installing is easier , just make sure that oring stays in place with an inspection mirror to confirm

Yes, I found good quality torx bits are absolutely essential. I picked up a set of 1/4" Williams Torx sockets for the job.

I would never attempt this job with Harbor Freight Torx sockets!

Hope everyone's doing well!!

Heres the pic of cracking the Compressor hard line bolts, these can be H6 or Torx, Ive found

Fresh new bit. Harbor Freight ok if it is new.

Long extensions

Clean out head with a pick. Use solvent if its greasy and full of crud. Get it clean!!

Put bit in, smack with 6 love taps with hammer, let weight of hammer head do the work, no Gorilla smacks

Out you come...
