Civic 1986 with heating and aged mechanical problem
 

I have a 1986 Honda Civic, Automatic Transmission, fully loaded, it has
few problems when ever the AC is turned on the car heats up. I have
been to car mechanics and after few repair touches they say now it will
be ok. But the problem persists.

The other problem is that due to i think age factor the speed of window
opening and closing has reduced a lot...

So if any one has a practically applied tip for me please advice.
