This is the second year my A/C has worked great and not required Freon. While driving down the road on a hot day and thinking how relieved I was that the leaks had been fixed, the A/c suddenly quit working. This was not gradual: great cooling one minute, then, when re-started no a/c. I discovered that there was not continuity on the low pressure switch. When I momentarily jumpered the plug to this switch, the compresor engaged, front fans came on. Is this likely a bad switch or some other problem? Thanks in advance. This is a great web site. Woody
