Does '91 Integra 3Dr LS 5spd-mt have high pressure switch for A/C ?

Let me adjust that question :}

Does the AC system on this car have a "high pressure relief valve" ?
location ?

If i wanted to install a "high pressure cutout switch"...  which one and
where should i buy such a creature ?

thanks again,

No. It has a "dual pressure switch", that handles both low- and high-
pressure. It's mounted the front surface of the compressor, closer to the
engine than the pulley.



Why do you want to buy one? Your A/C doesn't work?

Thanks for the help Tegger,

AC  does not work (well has not worked since last year). It was completely
void of refrigerant as there was No pressure on the lines according to the
AC gauges.

I figured now would be a good time to convert to another refrigerant like
134a .

After doing some research about converting to 134a there was mention of 134a
operating at higher pressures and the need for installing "high pressure
cutout" (if high pressure relief valve existed) to comply with EPA SNAP
regulations.

Plus installing  134a service port fitings and a new 134a label etc...

As for the problem ....

I figure there must be a leak  so i pulled a vaccum on the system to confirm
and it held  27" for at least 45 min until  i disconnected everything so i
wonder why/where the refrigerant went ? maybe bad schrader valve or a high
pressure leak . So i plan to search for  leak after i make all the other
changes.

Thanks again for the help.
