what is the best way to change the sensible heat level of the evaporator
In order to change the evaporator in Pt Cruiser, the entire dash has to be removed, then replace the evaporator, and reinstall the complete dash.
at the metering device before the evaporator
You must remove the evaporator case from behind the glovebox and disassemble it. The expansion valve is mounted to the evaporator.
The evaporator is the part on a vehicle with an air-conditioning system which causes the refrigerant liquid under pressure to change to gas.

Its under the dash, pass,side.And a bugger to change.
I am not exactly sure of what you are asking but there is not an evaporator valve. There is an evaporator core that resembles a radiator and there are not any parts that can stick. The only problem they have is leaking. There is an orfice that goes in the inlet to the evaporator and it has no moving parts.It can get stopped up and cause the high side pressure to get higher than normal.
Mid 90's Jeeps have nearly a 100% failure rate in the A/C evaporator...if you have not changed the evaporator yet, it's almost certain it is bad. Compressors also go bad but not nearly as often as the evaporator.
Book time for the evaporator is 2 hours, follow the a.c. lines to the fire wall and under the dash on that side attatched to the evaporator will be your expansion valve.
4 to 5 hours
