Where is orifice tube located on 2005 envoy
2005 GMC Xl doesn't appear to have an orifice tube where you'd expect to find it, -in its normal location.
Suggestion: if the fluid looks good inside the receiver/Dryer and the pressure is within range, send it.
Otherwise you're probably looking at a failed compressor and a clogged core or condenser at this age of the vehicle.

Can you tell me what
Firing order is 1, 5, 3, 6, 2, 4. Number 1 cylinder is up front. Why would you need the firing order, this engine does not have plug wires, each plug has its own coil pack, each coil pack is controlled by the computer.

Instrument cluster erratic warning lights, gauges stop working.
This is a common problem with an easy fix. If you are experiencing weird behavior from the instrument cluster it quite possibly is caused by corrosion on the circuit board on the back on the instrument cluster. To fix this you need to remove the instrument cluster. Refer to YouTube for this there are lots of videos shopping this, This step is much easier than it sounds, there are 4 screws and one plug. Inspect the circuit board you should see about a dozen places that have a dusty/crusty appearance (see the attached image). Clean the corrosion using isopropyl alcohol and a cotton swabs. Reinstall the cluster and your good to go.

There is a technical service bulletin regarding this problem with 2004 GMC envoy. Actually there are 3 separate issues with regards to the elecronic tailgate. The reason why the dealers are backordered is the part you want keeps failing after a time of being installed.
For the particular problem you have of the electronic latch not working, the bulletin recommends a inspection of the endgate connector C900. Look for the wires to be backed out of the connector or not properly crimped. To crimp you will need a crimping tool available at any electrical supply shop. The connectors can be had from the dealers.
The other solution referred to intermittent operation of the endgate but can apply in your situation also. For that, look for chaffing at the wire harness connectors for the endgate actuators located at the upper right and lower left latches. They have been found to be pinched up to 8 inches away from the actuators. In this situation it would be ideal to replace the connectors and install in a way so wires will not be pinched.
The other thing to look out for is dusty sensors. For this you will need to remove the tailgate trim panel and locate the 2 optical sensors on either side. You can feel them with your hand, they will be the size of a nickel. Clean all the dust under the trim. In addition to that you should open the switch and use contact cleaner to clean out any dust or debris inside there. There is no mechanical way to open the door once the electronic side has malfunctioned without damaging the door. I hope this helps.
