New to the group. I searched the site but could not find the information. I own a 1997 Ranger XLT with the 2.3 liter 4-cylinder and manual transmission with 86,000 miles (I bought it new but it is obviously not my daily driver). I abruptly started having no cool air when using the AC system. Pressure when the car is on is 85 psi on both the low and high sides.

I tested the low pressure switch after checking the relay and fuses, and I got no continuity. The switch seems to be defective.

However, when I look for the replacement part, all sources (even Ford dealers) give a part number that corresponds to a switch with a round electrical connector. My car's switch has an oval electrical connector for the wiring harness and has 2 prongs inside the oval connector. One Ford dealer told me that I would have to buy the switch with the round electric connector and buy a new wiring harness to adapt it to the switch. I prefer not to do that. I cannot read the markings on the switch. All but a digit or two have worn off.

While I have seen switches for other cars online that look like the one on my car, none of the web sites say those switches are compatible with my car. I suspect this is because the sites think the only connector is the one with a round electrical connection.

Does anyone have a part number for the low side pressure switch I have? If so, perhaps I can then buy the right one online. I do not want to risk buying one that resembles mine and have it not cover the acceptable A/C pressure range the truck requires on the low side.

I would rather get the right one up front rather than take a chance and buy one that is for Fords (but does not specify the 1997 Ranger).

I included photos if that helps.

Any help you can provide will be greatly appreciated.

 

Look on Rock Auto they have a WELLS 1S15782 that looks like the one you have.
