AC works intermttently. After turning it on, nothing happens until a few minutes later the blower very slowly ramps up to speed. Once it starts blowing, the air temp is excellent. Mechanic says compressor and coolant are fine, thinks it's the dashboard controller (?) Other times it doesn't come on at all.
If the fan slowly comes up to speed check the connections on the resister they over heat and melt then check the fan motor itself
SOURCE: turn the key but nothing happens all electrics
Not all replacement parts are good. I would guess that the new ignition switch is bad. Its also possible that the wiring harness is loose where its connected to the ignition switch. You could try jiggling the wires.

usually you have a leak in the system low on freon this dual system take more than 2 pound of freon second the blower works only on high you need the blower motor risistor usually it is mounted next to the blower motor
SOURCE: ac fan won't turn off
In my 2001 Town and Country without automatic temperature control, my heater/AC blower suddenly worked only when set on high. Usually, that problem is your blower resistor pack.
I had to search for the one in my van since the parts man wasn’t sure where it was except that he thought it was in the dash somewhere. (In some other vans it was under the hood.) My Haynes manual didn’t have anything on it except a picture showing it with the blower. I found it directly behind the glove compartment. Very easy to get to once you know where it is.
The glove box can be lowered all the way out of the way just by pulling in the sides so the rubber stoppers come out toward you. The sides bend easily to allow that.
The glove box being out reveals the resistor in the heating duct right in front of you. Just remove the two sets of wires and two bolts (10mm socket, I think) and the resistor pack slides right out. Then bolt in the new one an plug the wires back in (they only fit in one way). Fold the glove box back up and press the stops in to get them back in place and you are done.
The resistor pack only cost $12 and change at my dealer. It is part number 1-04885583AB which was a replacement for the same number with AA at the end, so I’m guessing they had a lot of trouble with the AAs and so made a better AB.
Last Winter my heater blower fan worked only on High. I changed the front heater/AC blower resistor pack and was surprised at how easy it is, but I had to figure it out for myself since my Dealer's parts guy was no help as to where the part lived and my Haynes manual was just plain wrong. This was on a 2001 T+C. I'd be very surprised if the 2001 Caravan was any different. Don't know what other year vans would be the same. I do know some earlier generations had this resistor under the hood and Haynes had is with the blower sort of behind the instrument cluster.
SOURCE: 01 Sebring convertible, AC was low on refrigerant,
First of all if your system was low on refrigerant there is a leak.You can recharge and exspect the air to work,how long it will last depends on the size of the leak.Somtimes the refrigerant can have a leak prevenative but this is for very small leaks.You need to have dye put in to system and use black light to find leak.they make kits at your local auto parts store that you can buy and do this your self.If you say it worked well for about 20 days, that is a fairly large leak.The reason why the compressor is acting so erractic is because the freon has oil in it and lubracates the bearings in compressor.When the system goes low the compressor will turn on and off to protect itself.Eventually it will stop running completly.Idont think you have an electrical problem,Ithink you have a big leak.Try what I said and good luck....Brian
