I found a site for Envoy & Trailblazer owners that has solutions, suggestions and discussions relative to owners of these vehicles. It is a free site and has tons of helpful tips on a seemingly endless number of topics. Like you, I need to replace my evaporator coil and even though I have yet to do it - I found a step by step guide - complete with photos. Now this is a big job but not impossible and can be done for a fraction of the cost the dealer wants. I'm sure which year Envoy it is for, but I don't think it changes that much year to year. Anyway, check it out yourself after registering.

Water leaks on the passenger side carpet when i run the air for an extented time on my 04 gmc envoy


The evaporator for the air conditioning is under the dash on the passenger side. Open the hood and look on the firewall for a rubber hose that sticks out of the firewall. This hose is to allow the water to run outside and onto the ground. Sometimes they plug up and the water can't get out so it builds up and drains onto the floorboard. Hope this helps...

    Where exactly is the orifice tube located at on a 1996 (DOHC v6)?


    it's in the high pressure liquid line.

    A/C Evaporator Core Orifice The A/C evaporator core orifice (19D990) should be replaced whenever the A/C compressor (19703) is replaced for lack of performance (internal damage). The A/C evaporator core orifice, located in the condenser to evaporator tube (19835), cannot be serviced in detail as a component of the line. If replacement is necessary, follow the procedure outlined for Liquid Line Removal and Installation. An orifice tube replacement service kit may be used as an optional service procedure. Refer to Section 12-00 for information regarding the use of an A/C Evaporator Core Orifice Replacement Kit E5VY-19D695-A.
    -----------------------------------------------------------------------------------
    A/C Evaporator Core Orifice Replacement Kit Installation
    1. Discharge A/C refrigerant system. Refer to System Discharging and Recovery as outlined.
    1. Remove condenser to evaporator tube (19835) from vehicle.
    1. Locate A/C evaporator core orifice (19D990) by three indentations or a circular recess in metal portion of the condenser to evaporator tube.


      A/C Evaporator Core Orifice Location
    32c58e1.gif
    1. Note angular position of ends of condenser to evaporator tube so that it can be reassembled in correct position.
    1. Cut a 63.5 mm (2.5 inch) section from condenser to evaporator tube at A/C evaporator core orifice location. Do not cut closer than 25.4 mm (1 inch) from start of a bend in tube.


      A/C Evaporator Core Orifice Section Removed From the Liquid Line
      ea95a2d.gif
    1. Remove contaminants from the two pieces of the condenser to evaporator tube.
    1. NOTE: The inlet half of the condenser to evaporator tube will be positioned against the A/C evaporator core orifice tabs when correctly assembled.

      Lubricate fitting with clean refrigerant oil and assemble orifice tube kit (with A/C evaporator core orifice installed) to condenser to evaporator tube. Make sure flow direction arrow is pointing toward evaporator end of the condenser to evaporator tube, and taper of each compressor ring is toward compression nut.

    I assume he used a leak tester and found a leak in the evap which is inside the plenum housing. Need to remove the plenum to get access to the evap. big job. If you are technical, you could remove the plenum assembly and let him replace the evap & then let you out the plenum back in. Then take back to have him evacuate and recharge system.
