Fans won't work a/c shorts it out.

[A83]

 

Both fans in my 83 won't work.  I recently installed a new battery and detailed the engine with Ultra Lustre which degreases but leaves a protective film so don't know if I messed something up.

When I lived in CT ( now in Florida so can't go back to the mechanic) the fan would short out when I put the air conditioner on.

Could not find the short so The mechanic put some sort of relay switch in which would restart the fan when the a/c switch shorted it.  It has been working fine for a long time but now when I start the car neither fan works and one fan tries to start but then shuts immediately down.  The other fan  doesn't start at all. Specifically it seems to short out when I turn on the temp control switch.

Any thoughts?

It was the relay switch _ $8.00 from Auto Zone - thank God - they  said I probably should run a relay for each fan.

Not a bad idea and not hard to do..
