Air condition works sporadically. I'm thinking fuse

If you had a blown fuse and it was for the air conditioning it wouldn't work at all. I would be looking into the A/C charge and/or the cooling fan operation or power supply i.e. relay. If the pressures are getting too high or low it can cause the compressor to shut off which in turn can give you your symptoms. It is strongly advised to see an air conditioning repair facility to diagnose the issue. I do not recommend adding refrigerant as you can overfill the system and possibly cause greater damage or poor performance. Good luck

Hello, When you have intermittent problems, a fuse will not be the issue because once a fuse goes bad, it will remain bad. You may be on the right track, however, as the A/C relay could be failing. To find the culprit, you will have to have the system connected to a manifold (set of gauges), and the system will need to be monitored via scanning. This will show any inaccuracy between the system sensors and the actual pressures. The relay can be checked at home, however. There are many methods, so look around for a video so you fully understand the method you are most comfortable with.
