      Default A/C evaporator removal

      I need to remove the A/C evaporator from the car to replace a blocked expansion valve.

      I've looked at the TRSM and it would seem to be quite straight-forward, but somehow I have my doubts. Has anyone done this (I mean in a gentle way, not hacking it out of a scrapper) and can provide some tips?

      Cheers,

      Trevor

      Default Re: A/C evaporator removal

      In case it helps someone in the future:

      Remove trim under glovebox (three screws)
      Remove footwell door side trim (nut, and loosen two front screws on sill cover)
      Remove glovebox (two screws at hinges)
      Remove glovebox brace bar (10mm bolt and a couple of screws, you may need to remove the transmission ECU too by the side as it attaches by one 10mm bolt, for auto anyway, not sure about manual. Worth doing anyway as it gives access to the 3 screws of the fan which you'll probably want to clean while you're in the area, not 100% necessary for this job though)
      Remove glovebox latch/back panel (2 screws for latch, and some screws and plastic poppers). This is a bit of a squeeze, but bend it gently and it will eventually come.
      Remove large engine ECU (2 screws, a third one will be empty as already removed)
      Disconnect temp sensor at front of the evaporator box, and the connector fixed to the top of the box
      Disconnect both coolant lines on the firewall in engine bay
      Undo the various screws and nuts holding the box to the firewall (3 nuts) and other boxes (4 screws)
      Gently wiggle the whole box out. I loosened the bottom nuts x2 on the fan box too, which may help a little, as does removing the two metal lugs on the dashboard tube at the top. Once sagging down, unscrew the metal bracket on the top that holds a piece of loom on (1 screw).
      Now pull the box out of the car.

      Once you have the box in your hands, getting to the evaporator inside is just five screws and two clips.
