Did you need instructions for changing the expansion valve? Sorry, not much info came through.
The expansion valve is located on the passenger side of the HVAC module assembly. The entire HVAC module needs to come out and then the expansion valve can be removed and replaced. The entire dash has to come out. It's not an easy job:
Here is how the top dash comes off.
Here is the location of the valve once the blower module is out.
I just wanted to check whether you still need help with this issue.
Please let me know if you do. If not, please don't forget to rate so Just Answer will know to pay me for my time.
