Question re: Using R134a gauge on my Nissan

I have a 96 Nissan Sentra. I have had this car since its birth and never had need to work on the ac system. At the end of last summer, I noticed that it was blowing warm air and decided to postpone working on it until the Spring. Now that it is Spring....

I bought an R134a gauge set so that I could determine the high and low side pressures. My experience with this process is with the old R12 gauges. I bought the gauges from Harbor Freight online and found that they don't seem to work with my Nissan! The fittings on the Nissan are the "quick connect" type. My gauge has the "screw-on" type connection that the old R12 systems had. The "quick connect" part of this gauge is at the attachment of the hose to the "dials-gauge" body.

Does the Nissan have different ac connectors than other cars? If so, can I get an adaptor to make the gauges I now have to work on it? I would appreciate some suggestions.

Federal law dictates that R-134 systems use unique fittings (quick connects) for R134. So, no, Nissan isn't different from other cars. You got the wrong hose ends from H.F.

1/4" inverted flare to R-134 adaptors are quite common.

You have the right gage set. The quick connects connect to the car. The extra quick connects on the gage set are for storing the hoses without allowing dirt/crap in there. You screw the lines to the gage and quick connect the other end to the car. Good luck.
