I want to install AC in my 89 turbo caravan. I know this is a bitch of a job, so I'm prepared for that. I'm wondering if there's anyone out there that has done it that can offer any tips. I have most of the underhood stuff, and that's the easy part. I'm looking for a donor van, but might end up having to buy what I need online used, so I want to determine everything I might need and what can it come from. I'm figuring 84-90 would be a safe bet, at a glance it looks like 91-95 models wouldn't work.
I need the heater box and heater/AC control. Was the venting or ducting any different between AC and non AC Caravans? Any other little interior bits (plugs, harnesses etc) that might be required?

Thanks Jan. I'm hoping the main harness under the dash will support the AC without too much modification. I know that on my omni for example there are differences in the dash and center console for the vents, but I can't see that there is any difference on the mini's, at least not on the surface. Time to find the donor...
