the switch is open, its cutting out everything... output zero, 12vdc id good, or what ever battery reads now. its just pressure switch, that is all.
1 its bad
2 the pressure is too high
3 the pressure is too low.
only 3 possibles.
glass.
Check the Site Glass
"Many receiver driers have a site glass on the top.
small window allows a view of the refrigerant moving through the lines.
With the system running, there should be no bubbles in the lines.
If there are bubbles, this indicates refrigerant levels are low, in which case there may be a leak in the system.
Oil streaks and froth in the lines also indicates that refrigerant levels are low,
while a milky fluid indicates the receiver drier is leaking desiccant, according to the Pro Car Care Website.
Note that when the system is off, some bubbles may be visible in the lines. This is perfectly normal, and not an indication of low refrigerant levels."
the hi/low switch protects the compressor , for both bad conditions, low freon, and too much.
the 2 pressures are stated in the fSM
they are:
30 psi OR over 382 PSI. (95' it is, 28 and 455 psi) the newer cars 1995+ are R134a...
are you running R134? in the 1992 is not set up for R134.
and this 1992 orig. switch is just that, set for R12. levels.
the only way to tell is to use manifold gauge set. but that wont fit old R12 system.
the the right tool, you can see if the switch i working or its telling the truth, and cutting out for right causes.
