Cannot locate source for this part. Tried Mazda, NAPA, Santech, 4 Seasons, AutoZone, etc. Now trying other Mazda models from 1993 - 1999. This part (in my opinion) should not be RX7 FD specific, but more of a universal part. HELP!!!

 

Can you post a picture of the part you are trying to find?

Do you have MANA or Denso AC?

Are you referring to the thermoswitch on the evaporator or the one by the receiver/drier?

 

Cutoff switch is locate on 1/4" tubing/line from the Drier, just below the battery's lower cover. Some posts recommends Santech MT0621, but this item is for the low pressure.

 

When mine leaked, I used the following which was a perfect fit.
Santech, Forth Worth TX , MT0621 binary pressure switch for A/C, was made for the Miata.
