MY CONDENSOR FANS COME ON FOR ABOUT 1 SEC. AND CUTS RIGHT OFF WITH A/C ON OR WHEN TEMP GETS TO HIGH THEY CUT ON OFF

First, we need to check the controls of your cond fan. Now, my nerxt question is, does your A/C work normally? Because turning on the A/C is what triggers the operation of the condenser fan. If the A/C works fine and the dash switch seems ok, then check the triggering circuit for the fan relay, make sure that there is a signal sent to the relay ( usually a ground) when you energize A/C system. If not, then there is a problem with the controls of the condenser fan. Also, verify the powers and grounds going to the condenser fan relay and the fan itself. These inspections should give you a start.
