If you are talking about the AC expansion valve, there is no adjustment. You replace it with a new one, they are cheap! They get clogged up with goo over time, the failure mode is found when you check your AC pressures. You start to add some more of the coolant and the pressure suddenly soars. Blowing it out with air might buy a little time, but in the end you will end up replacing it to get the AC to work right.

What I think you are thinking about is the heater valve with does have a small adjustment. Most of the time folks find that the heater is on all the time and want that to stop.

Hope this helps,

Paul
