AC line Switches - ZR-1 Net Registry Forums

Subfixer · 07-11-2019

I'm swapping out the entire AC system from my 92 R12 to the 94-95 R134a system.

I've got everything I need except 2 pressure switches, which I can't seem to identify correctly via the many vendors out there.

The AC system has 3 pressure switches. One on the Evaporator itself, and 2 on the line that runs from the Evap to the Condenser.

I need the GM or AC Delco part numbers for the 2 on the Evap to Condenser line for 94-95 ZR1.
These 2 switches are different from 90-93 (R12) vs 94-95 (R134a).
The thread sizes changed.

Thanks, Paul
