AC Evaporator core replacement on 92 400E

Okay, I finally broke down and started the disassembly process on my 92 400E to fix the dreaded Leaking Evaporator core. Yesterday I remove the Passenger Air bag and lower dash, the Driver lower dash,the complete center console, AC controller, Radio etc., all air vents and am up to the Instrument panel. Will hopefully do that tonight. Wish me continued success and patience to go slowly and no break anything. Can some give me the secret to removing the instrument cluster??

The inst cluster should just push out from the back or pull out from the front if you can get the proper hooks to attach to it to pull it. Not sure if this one has a speedo cable or electronics but I know on the W123 you can go to the speedo cable at the tranny and disconnect it to get some slack on the cable to allow you to pull it out a little further to get you hand behind it and unscrew the cable.

I'd think that since you have the lower part of the dash removed on the driver side, you should be able to reach up and push it out from the back.

I will be thinking of you. Replacing the core on my 93 was without a doubt the most exhausting automotive experience I've had in some 35 years. Getting everything back in right and tight seemed endless. Perhaps it was my aging bod stuggling in odd positions. Good luck. It was great when it was over.

I don't think you're supposed to remove that crossmember are you? Isn't there a danger of the windshield cracking or something?

Only if you lift the vehicle.....I think

You pretty much have to remove it. The heater Box is secured to it. Maybe you remove it(the Box) and then put it back or something. Anyway, my car is securely on terra firma and it ain't moving till I get all the guts back in. I'll have to do as J.Hidalgo and others have done and drive the car to an A/C shop (partially disassembled to confirm that there are no leaks. O' Boy I can't wait to see the look on their faces when they look inside and see the dash....

I remember the look on my face when I saw MY car down to the airbox when I replaced my vacuum elements!! I thought, "what the hell have I done?"

Are you taking . . .

any pictures? Probably would be nice to look back and see what you got yourself into.

Also did you consider trying a 'leak sealer' such as Super Leak Pro first? http://www.cliplight.com/ssp.php#Distributors

I use it recently and if there was a leak in the evap, it fixed it.

No pics yet but.....

I may do a documentary as I put it back together. I'm waiting to see how hard it really is before I post a step by step on the process. To this point it really hasn't been too bad. Just taking my time and not being in a rush is making all the difference in the world. I'm working out of my garage and even with the car doors open and the garage door open with an attic vent fan, its still HOT and don't even talk about the humidity. 5 minutes into the process, I'm dripping wet. So I have to wait till it gets cooler..~7:00 but then I'm in a time crunch.

Albert,

I did take my car to an A/C shop after I replaced the evaporator AND put everything back together. If you notice, the evaporator inlet and oulet is located in the engine compartment by the firewall, on the drivers side. So, my logic was, if you have a leak, it would be outside the dash or, in other words, "reachable". If your evaporator is new, I would not worry about leaks or, you can pressure test it BEFORE you install it. Do check ALL the vacuum lines under the dash to include the "pods" and replace them while you are there.
Did you remove the steering wheel?
Good luck!

I got to throw this in, your windshield wont crack with the crossmember out ( unless) you lift the car on a rack, then you have problems. Make sure you replace the vacuum elements unless ya wanna go back in later. Evaporator on the 124 is one of the easiest just take your time and you may wanna throw some new bulbs in the illumination since your there. Good luck.

Thanks

Thanks J.H....I did not remove the steering wheel per your/others instructions.
Thanks Koonce, I was going to bring it out to BR to have you do the job, we spoke about bring it out one weekend and doing a lay over in BR for a 1 day repair. The price was definitely right since I do have(had them for 10 months now) my parts already. Then i got this guy, a tech at a local MB store that said he could do it for a pretty good price here at my home. I thought great, no drive, a weekend project and $500-600 csh to the guy Tax free...Win-Win. But he stalled and stalled and stalled.....Then it got hot about 2 weeks ago. Then I got HOT and said the hell with it all. I'll do it myself. And so I shall. So far I gotta tell ya, it ain't that bad. Unless the hard part starts at removing the heater box and ultimately the Evap core itself. Please tell me its all pretty much straightforward from here on out and that the rest will not put up any particular resistance... Please, Pretty Please.........
