I have a 99 Jeep Grand Cherokee limited, 4.7 V-8. Haven't really had to many problems with it, except for the heat and A/C has not worked since I've owned it. The blower was also out but i wired it straight to the battery and it works fine. but just blows cold air but not A/C cold air. My knobs light up and display the temp. but it just blows out cold air. I just wanted to ask to see if anyone else has had this problem before i pull the dash, witch i hear is a job.

but thanks for the help.

Nick.
