ABS Problem

My husband replaced the brakes on our 1996 Dodge Intrepid. He’s done this a few times with no problems. This time the ABS light goes on and off while driving. The brakes work fine and so do the ABS. Just, the light keeps going on and off… HELP !!! PLEASE… Anyone. One income family and I on 20 meds.Shops around here charge almost $100. an hour Hardly have money for food letalone a repair shop Please

If possible clean the sensors with high pressure air.

Thank you so very much. I really appreciate your fast response…
