2016 ford escape battery or alternator?
So my girlfriend has a 2016 ford escape SE the last two days I have had to jump start the battery. Weirdly enough after a couple of seconds on the jump pack it will start right up. I noticed blue corrosion around the positive terminal today she said the other day when she tried to start it it hesitated and dash lights flickered. There are no aftermarket parts/electronics battery picture for reference. Also I took it to advanced auto to have the battery tested and they refused to do it and said they couldn’t reach the negative post…. I’m at a loss on what to replace alternator or battery
