a/c help still needed--getting closer, but...

[brian_wagner at sbcglobal.net (Brian Wagner)]

1) they are separate units, generally looks like one because of the gunk
wrapped around that area. A new expansion valve is cheap and the thermo
control is part of the slider assembly

2) I don't have one

Subject: a/c help still needed--getting closer, but...

i *thought* i found the source of my a/c troubles yesterday when i found a 
wire that got clamped in a bumper bolt and was shorting to ground. fixed it,

no dice. proceeded to rip into my fuse box. all wiring there seemed good, so

i pressed on. my trouble was coming from the thermostat in the control head.

looks like it's a switch that closes when the temp rises, completing the (+)

to the a/c when closed.

the thermostat consists of a little capillary tube going to the expansion 
valve. on the thermostat end of the tube, it has a little diaphragm, which 
presumably expands/contracts against the switch depending on the air 
temp(maybe?) within the hollow capillary. questions:

1. does anyone know if the expansion valve/thermostat are separate units? 
they appear to be one unit...
2. does anyone have a spare expansion valve/thermostat that they can test 
for me/sell to me?

tia,
