1999 Ford F-250 Q&A

1999 Ford F-250 Question: a/c issues

Doesn't blow cold. Had system checked...'appears to not have leak'by draw down test. system charged(33oz added, compressor kicks on and off at 3-5 second intervals. still no cold air.....We (shop, not dealer, and I)can't find low end to hook up for pressure check. Where should I start and once fixed, will it actually blow COLD air? Hearing horror stories. -
Answer 1
3-5 seconds is too fast of a cycling time. the compressor is not even working long enough to get any air cold ( as you know ) check all the pressure shut off switches. did you completely evacuate the system for at least 1/2 hour before filling it? Good Luck! -
