Explorer a/c help

Hey all, I have a 2000 explorer and the a/c stopped working. I recharged the a/c because freon was low per the gauges and then the compressor would kick on, then the pressure would drop in a matter of seconds and it kicked off again. Then the pressure goes back up, compressor kicks on again and this just keeps doing this over and over but never gets cold. What's wrong? My a/c worked last year. Anyone have any idea?

There's a set of FAQs in the HVAC section. While written with the F-series in mind, it also applies to your situation.

45 psi on both the high and low pressure side, or are you only monitoring the low pressure side? Does the gauge needle shake at all or just drift to zero?

45 just in low. Needle just drops steady(and fast).

You need to watch both high and low side. To me it sounds like your system is either plugged, or you are undercharged, but its impossible to tell unless you watch both high and low. This is part of why the DIY cans with the built in gauge and worse than useless.
