Chickenlady, pretty sure your ceanothus is dying. Cut it back hard and it will not regrow, in my experience.
25 years for a ceanothus is a very long time
Ive grown several over the years.....they thrive and many are huge here in Cornwall. On average they last about 5 to 8 years. Usually, from nothing, they suddenly die back and their demise is rapid.
Ceanothus don't like being pruned but, ironically, they need to be restrained and initially flower better because of it.
Chickenlady, check the branches and see how far the "die back" is. Nothing will regrow from dead wood...of course. Think about getting rid of it now....don't plant another ceanothus there
