I have a problem with my rear A/C in my Venture. I have owned this vehicle for over 4 years and basically we love it. I have read all of the issues on this board and I guess I consider myself lucky. I am wondering if there is a second set of connections for the A/C in the rear somewhere. I have no cool air coming from the rear vents unless It is really early in the day. I am in the Phoenix area and A/C is a necessity. Is there a second compressor or possibly a secondary place to check refrigerant pressures? I have already done the check under the hood and pressures are good! Please, any information that would help me out here would be greatly appreciated. Thank you!!!!
