I have a 2003 Jeep Wrangler. I am having an issue with my AC not working. Initially I tried filling it with the leak repair type freon, and it worked for a day or so. Then I took it to a mechanic friend of mine who pressurized the system with the freon that had the dye in it so that I could find the leak. The system worked for about a month or so, and then stopped working again AND with no indication of a leak. My compressor will constantly kicking on and off. The system seems to still be pressurized as well. My friend suggest it may be a low pressure cut-off switch. What do you think?
