You have a 1991 ford explorer my battery idiot light just came on and the amps gauge is showing 10 amps the car starts and ruNsbut the ac doesnt work is this related what do you do?

the ac could be related and if the battery light is on it means that your alternator is not charging properly which in turn could stop your ac from working due to lack of power I would change my alternator and see if that fixes your problem.
