Curly, The Dodge was an '88 Grand Caravan. It's A/C compressor failed IIRC. Ned I suspected it was pre-MB. The 97 and later vans are pretty good. By 99 they were pretty dependable. the little square boxyones like your 88 had problems.

Re: [MBZ] OT Mini-van dual zone a/c
For my '75 Dodge van rear evaporator in '75, I ran regular, rubber AC hose from engine compartment under the vehicle (secured by tie wraps/zip ties) and up a rear, inside corner (covered on inside by a factory panel) to the evap mounted on ceiling immediately inside the rear doors. Still working great when I sold the van 17 years later.

Re: [MBZ] OT Mini-van dual zone a/c
'Certainly should be able to if the refrigerant lines to the rear evap are blocked/rerouted so as to isolate the rear evap from the system and the lines for the front evap are connected so as to provide a complete circuit only to/from the front evap. In '75 I added an AC evaporator to rear of a '75 Dodge; merely spliced T fittings into the refrig lines under the hood to send refrig to rear evap (Frigiking) in a parallel manner. If your evaps are in series, merely cut/block lines to rear and install a coupling to reroute the refrig back to compressor and condenser without gong to rear. Fill system as appropriate.

Re: [MBZ] OT Mini-van dual zone a/c
I think I would be complaining to Toyota too. Notwithstanding the fact that the vehicle is 10 years old, why would the evaporator be corroded? I had an 86 Chevy Suburban with dual air and had some trouble with the aluminum pipes under the vehicle being eaten by salt until I figured out a way to provide some protection to them but I never had any issues with the evaporator. I replaced the pipes twice at $300+ each time but it sure did not cost $3600. RB On 11/08/2015 2:11 PM, ned kleinhenz via Mercedes wrote: My wife drives a 2006 Toyota Sienna.
