rear ac expansion valve, where is it?

[93burb]

On my 93 suburban the front ac vents work great, but the rear ones blow out warm air. I have read the forums on this same problem and I want to check the expansion valve in the rear, but where exactly is it? do I have to take the entire rear AC apart to get to it?

Yea..pretty much.
If you take the right side panels off you will see the HVAC unit..You can cut the plastic housing to gain access to the TXV...( use a rotory tool to cut a neat hole and you can put everything back togather)
You will need to have the refridgerant reclaimed before starting the repair
