On my silverado

I tried turn on AC but looks like it won't turn on. Light on switch keeps flashing

Crank truck. Its not the air conditioner motor. The coolant fan races high and low on its own, mostly high speed

Worked 1 week. Came on again-check gas lid-took to 3 different auto supplies stores-registered oil press switch,Now dealership trying to fix after 400.00

Ticking coming from the engine. Only at idle does it tick. Have heard the oil pump has a problem with it. Not the lifters, valves or cam. If anyone has had this problem fixed I would like to know
