AC colder on right side

I have a 2000 Venture that blows colder on the right vents. Any ideas folks?

Thanks

Yeah, the Evaporator is in the far right side of the dash. It will be colder there.

Is it hot on one side and cold on the other or what? Take a thermometer and measure the temp in either side after running awhile. (preferrably in the shade.)

Typical low charge scenario, the evap inlet feeds the passenger side- the evap outlet feeds the driver's side-- when charge goes low (due to a leak) then there is not enough refrigerant to cool the entire evap.....

Find and fix your leak (shaft seal and compressor body o-rings are number one locations- then evac and recharge to factory spec and cooling will return to driver's side.

never thought of that, guess I will check the charge on mine.....

If you have the rear heat/air option, the system takes two cans of coolent...

I recharged our sytem this spring and couldn't get it completly cold until I put a second can in.

My leak was at an o-ring. Easy fix.

My rear air system took 4 cans of R134a, at 12oz/ can and 48oz system.........
