Hi Guys, you helped me big time once before so here is another ask: I store my 94 Cherokee 4.0L in Baja and use it for a couple weeks a year. Since our place is pretty remote it is hard to get into a shop for any period of time.

Last year you clued me in to replace the blower motor resistor to help my AC work right. I replace that and then had the system charged. Then I got this huge howl from the system when operating. It is only howling when the AC is on and it comes and goes. I attached an MP3 I recording rolling down HWY 1. Any ideas on the fix for this are appreciated.

Thanks, Scottie
