Continued starting problem

I posted a question about an intermittent starting problem the suggestion was to replace the starter. We replaced the starter and the car drove fine for 3-4 days and now it is doing the same thing. I can drive it for a while but then it won’t start. It acts like the battery is dead but the battery is fully charged. When the starter was replaced the battery was checked out and the connection was cleaned to remove the corrosion but after 4 days there is alot of corrosion on the battery already. The automatic windows and door locks stopped working from in side the car for just a 1-2 minutes. Could these problems be related? I don’t have a lot of funds, any ideas? It is a 2006 Dodge Caravan

Sounds like they only cleaned battery clamps,is so they need to clean the other end of hot and ground wires and also look under coating of hot wire close to battery for crud.

thank you

I have a 98 dodge caravan and am having the same issues. Did it help to clean the battery?
