2 part question guys-1. a/c condenser fan fuse keeps blowing so I replaced the condenser fan motor to no avail, it seems to happen (after the ac is on and the fan has worked for 5 minutes) with a slight jolt to the rpms as if their was a vacuum leak. Also 2. the a/c was ok at 75-80 degrees but at 90 the car is a sweatbox, I tried to charge it with new style refrigerant as i've seen it work on other cars but attempting that just made the front and firewall connection pins start leaking. I covered them with the plastic caps and now there's no cold air whatsoever. Ohh by the way the belt starts squeeking at takeoff w/ the a/c on but goes away in 2nd gear/higher rpms. Heeelp, any input would be greatly appreciated. thanx.
