Hi Folks:
I rebuilt my auxiliary water pump( aka recirculating pump) using the procedure given in following thread. However, I did not change the carbon brushes. For me it was too complex. Its a very nice procedure by '79 Super Turtle.

It was a little hastle to get the motor cover off but I did it.
Then I did a hail Mary- I got the electric motor cleaner spray from NAPA and cleaned the motor especially the carbon brush and the carbon brush contact area.
Cleaned the magnet in the housing as well with the spray.
Let the whole thing dry nicely.
But that as far as I could go with my skills, (carbon brushes looked too complex to mess with).
Put the motor back in the reverse order.
Did not attach the pump yet.
Then the testing part, using a 12 V DC supply from AC to DC adapter (you will find many of these in your house), and WOW it worked.
I let it run for 3-4 minutes then reversed the polarity and let it run for 2-3 minutes.
All looks fine.
Then reassembled the pump and tested it in the car.
Works like a charm.
I don't know for how long but for now I am OK.
I plan to put 1 Amp in-line fuse so as to protect the other circuits in case the pump starts drawing up too much current, this way I protect the pump and the other components like ACC board.
My advice, If you can get a used one for 25-30 bucks get it and replace don't go through the hassle unless you have time on your hand, and also be aware that you might not be as lucky as I was just by cleaning it.
I am attaching the image file for the pump component.
Thanks hope this helps
