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

I was looking here

to find the part and where it might be located but there is nothing labeled as **high** pressure switch in the parts of the AC parts list diagrams. Which is why i ask the question.

thanks for any helpful answers, robb

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, robb

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. robb
