I have a 1999 Jeep Wrangler Sahara and my a/c seems not to be working anymore. It started off by turning off for about a min then turning back on it own. Recently it just never cut back on. The compressor is kicking on but no air is coming out the vents. I've tried turning it off and on over and over again, but no use. I really need help since I live in Texas and boy is it hot. Thanks.
