Rear air temp on 2011 Extended

[vortec2011]

Looked at a 3500 extended van recently. The air coming from the front vents felt plenty cold, but the rear vents still felt warmer after the 10-15 minute test drive. The rear air was definitely cooling, but it didn't seem as cool as the front. Is this normal?

Would definitely check pressures. The only vehicles I've owned with dual air-conditioning were Yukon xls and they always just worked. My dad's conversion van had issues like you're describing... In his case it was a pressure issue once and an expansion valve issue another time

More than likely your air needs recharged very cheap to do. The rear is air is only air conditioning when the front gauges are on max. Read the owners manual. I thought mine did not work until I learned that one.
