Most of the time if your AC stops working on a 2002 to 2008Dodge Caravan it is ... 2005 Dodge Grand Caravan 3.8L. No luck so far finding that ...
cause its burnt out from the worn ac motor drawing too much juice--need a new motor--change the heater core and ac evaporator at the same time-save lotta $
To replace the AC Evaporator core you must remove the dash from the car, a very complicated job, a factory manual is not an option here. You can access the factory manuals for a fee at this site www.alldatadiy.com, it is what shops use. The job takes about 12 hours at home.
Its a big job, The heater box needs to come out, which entails discharging the AC, removing heater hoses, and hardware at the firewall. The complete dashboard needs to be removed and swung out of the way, steering column lowered , and heater box removed and disassembled for evap replacement ( simplified )
There is what is called a "blend door" that controls the flow of air to either the heater core for heat or the evaporator core for cold. It switches back and forth via the temp you request. The servo motor that controls this may eithere have gone bad or the the door could be in a bind. This involves getting to the top or sides of the plenum which air flows through. Removing the glove box door and compartment will assist in accessing this. I hope this helps
That sounds like the AC condensation drain tube/hose is plugged up.
The AC evaporator/core condensation drain tube is located on the passenger side of the fire-wall towards the bottom of the fire-wall, (it resembles a heater hose that is coming off from the fire-wall and it connects to nothing, and it is just to drain the AC condensation) and it is easily viewed from under the vehicle. Use long pipe cleaners folded in half to clean out the AC drain, and be very careful that the AC evaporator/core, or the heater core is not damaged from using any hard or sharp objects to clean out the AC drain.
You may want to have the AC cleaned out. This involves removing the evaporator and cleaning it inside out. While you have it out, have the vents check if you have the "door" that lets the outside air in if it is working, Just to be sure that the dust did not come from the outside. You may also want the AC freon checked out.
