  • This weekend's project.

    I'd much rather be out in the shop with the A/C on making chips but youngest daughter's car A/C's been dead for several months. We've been lucky most of the summer with mild temps but things are getting nasty (heat index in the 105/110F's) here in the mid-south so it's time to bite the bullet & replace the !^#!%!* evaporator in the her 2010 Focus.

    Can you believe that??!! I'd love to strangle the bean counter that decided to save 27 cents & change the fluxing process or whatever makes these things start leaking in such a short time. It's a great little car but it's absolutely unacceptable to have this kind of failure. Ford says to replace the entire heater/air con assemble for $$$$ but Murray supplies the evap core for less than a $100.00. Trouble is, ya gotta explode everything down to the firewall to get the box out. Once it's on the bench, then you take out a zillion screws & other gimcrackery to split the box & finally get to the evap core.

    I'm too old & fumble fingered to tackle this by myself but fortunately good friend & co-worker Mike W. volunteered to help (he does all the work & I fetch things & say encouraging words & try not to get in the way.) He says it's a piece o' cake compared to the Jags & Rovers he does the same sort of work on during the day.

      Holy sh1t !!

      I had the first pic only scrolled half way down to read your main description, after reading that
      and viewing the whole picture, ... just wow.

        ugh, I have a 2005 galaxy with the same malady we think. The pipework chills down, the computer tells the clutch to engage correctly but it doesn't get cold. It has two of the evaporators (a seperate climate control for rear passengers, its a 7 seater), so it could still be something electrical (flap stuck maybe?), unlikely both went out the same, but thats what the local aircon guy says but he can't do the job, or won't take it on more like.
        I've been putting off doing it for some months and I can see thats a good decision, though I bought my wife a new car and she still wants the galaxy fixing because apparently she still NEEDS the galaxy because its bigger and NEEDS the aircon. I pointed out my landrover just has flaps which open under the windscreen and manual door winders for its aircon so therefore its not manadatory but she's not in agreement with me on that point.
        Im going to print off your pic of it with the dash out, and say "look, it really is the big job I've been telling you about while putting it off!"!

          Well done! I did the same a couple years ago, on my old '91 Golf. I don't think it was nearly as much of a chore as on the Focus ... there was no modern wizardry to get in the way of things. In my case, the heater core and evaporator weren't leaking, but all of the blending doors in their housing/box had rotted out. I ended up re-lining the doors, and replacing the heater core while I was in there.

            Thanks for the empathy fellows. We got the new one in, the system vacuumed down & holding for 20 min, recharged w/134A & blowing painfully cold air by 2:00. Every screw, plastic plug, harness clip, bolt & nut went back in their proper place except one small heatshield retainer button that went ZING & disappeared. No interior trim parts were broken or lost. Job well done thanks to professional help.

            Whew, what a relief!! Now I gotta figure out a good payback for my bud Mike besides the $200 cash my daughter's giving him. Hmm, steak dinner, ribs & beer...I'll figger sumthin' out.

              Typical Ford. By the book, it takes about 12 hours to replace the heater core on the older (89 and earlier) Crown Vic. I got so I could knock them off in 6-7 hours (including my own powder-blue 89. I miss that car).

              The Fairmonts with A/C were so bad owners junked the car instead (the Fairmont was junk out-of-the-box).

              The first generation Escorts were a snap- take the glove box off and remove a cover- the core slid out like an eight track. 20 minutes, tops.

                I'm pretty sure on most cars the heater core/evaporator is the part they start with when they build the car. Everything else is added afterwards. Glad it turned out well for you - never a fun job.

                  I had the same pain on an audi, i think it took me about 2 days to fix the damage i did fixing the trim back!, never again, ok we all say that shortly after a clutch change, it seems you get to completely disassemble the whole car to do both jobs, I'm surprised you don't have to remove the trunk lid to change the back lights!

                    Patience and a butter knife do wonders in these situations. I do similar every few years to wash out the hvac ducts and make sure there arent critters living in them, youd be surprised what comes out of garage kept vehicles.

                      Those pictures remind me of last year when i had to take our Toyota Hilux truck to the aircon fixing shop - to remove a dead rat. I could not believe the amount of stuff that had to come out. And the smell !!!!!

                        Maybe you should try this method:



                        Or get a 12V to 120V inverter and mount a window A/C unit for a "Redneck" version. I've seen a picture somewhere... Yeah!

                          That is just awful, I cannot believe all the crap you had to go through and there's nothing worse/more confined than under dash work...

                          There's certain jobs I just wont do and that's one of them, I will take a quick look to see what's involved and then make a decision, I did have a huge victory quite awhile back on some vehicle that required the entire dash to be removed and disassembled just to get to the temperature probe, I looked it over, drilled one hole in the plastic A/C plenum, got to it's internal anchoring screw or something like that, slipped the old one out and the new one in - installed a rubber plug where I drilled through ------ made unbelievable wage and saved the customer a ton of monies, everyone was very happy and it was a quality job that did not hurt a thing...

                          If a car manufacturer has this kind of "build practice" then they should at least be installing evaporators that are Nasa grade and will never fail...

                            I thought you said "acorn fixing shop". I guess that's what naturally comes to mind after dealing with red squirrels.

                              Yup, me too. One decision I almost made a couple months that would have been disastrous was to recharge the thing and add SuperSeal stop leak. I've used their R22 stop leak in my house a/c and it worked a treat. The manuf said on their website if the leak was large enough that the system leaked down in 2 weeks, don't use it. Hers leaked out in 2 or 3 days. I found out later that Focus's (Foci?) have some special type condenser that will not tolerate any kind of stop leak and will just plug up with no hope of flushing the stuff out; replacement is mandatory.

                              I would have never tackled this one myself without my bud Mike saying he'd do it. After over 30 years of watching him perform miracles, I had no doubt it'd get done quickly & correctly.

                              The thing was actually not too bad, most of it snapped apart like a Lego and most of the screws & bolts easily accessed with power tools. There's 2 b!tch-a$$ dash bolts, one on the left end of the dash, accessed through the door jamb & one in the center front next to the windshield. Both required a unique stack of 1/4" drive extensions & universal joints that Mike came up with without missing a beat.

                              The spring-type heater hose clamps required a tool I'd never seen before. It's a cable operated miracle tool. One end snaps onto the clamp and the other end is a pair of pliers with a locking dog. You squeeze in comfort over here and the other end compresses the clamp & locks down. Removing those hoses would've been a nightmare without it.
