Fan won’t turn off
1986 Iroc with 305 carb motor. Single fan. The fan will run continuously unless I disconnect the battery or unplug the fan pig tail. I have checked the following: temp sensor near the thermostat. Temp sensor near the plugs on the passenger side, ac clutch fan relay, and the fan relay located near the radiator. Is there anything else to check? When I unplug all of the items above the fan still continues to run. I have been told it could be a bad fan that is grounded out or the ecm. Any help will be much appreciated.

Re: Fan won’t turn off
Have not had any improvements done. When I disconnect the relay fan still runs. I pulled the plug just now from the back of the fan and checked for juice with the switch off. I have juice on one side of the plug when the switch is off. I’m thinking the problem could be between my pig-tail that goes into the fan and the relay?

The fan relay is located on the firewall near the brake booster and master cylinder. Unplug it. Fan go off? should. The relay you unplugged is for the throttle kicker.

Instead of telling us that we're all full of crap, (not that we necessarily aren't; just, our cars work, and yours doesn't, and when ours don't, we know what to look for to fix them) check your wiring carefully for "improvements". If I were the betting kind, which I'm not, I'd bet you'll find some.
