The car is a Nissan Versa 2017. Was told this was preventing the engine from firing. If you need any other information just ask but I am car illiterate.

A seized AC compressor can stall an engine by putting too much resistance on the serpentine belt. But if the AC compressor clutch is not engaged, (AC is off) it should start and run just fine.
Need more information. Though, I have had a car where the AC compressor pulley seized up, preventing the crank shaft from turning, which prevented it from starting. You would be able to remove the serpentine belt and start the car still, but would have no alternator/water pump, so can only drive it short distances.
Like everyone else said if it’s.sezied.it could lock up the motor but other than that it sounds like bullshit
compression failure. not compressor failure. The compressor is part of the air conditioning system. Compression refers to engine compression. Gasoline enginges work by pumping gas into a small chamber. That gas is ignited by a spark. The resulting explosion forces a rod to move down. Then the same thing happenes on the opposite side. The opposing rods are connected, and the opposite side rod going down makes the first rod go up. The rod going up squishes (or compresses) the gas in the little chamber so that the resulting explosion creates enough pressure to move the other rod(s). Rinse and repeat and the rods going up and down spin a big rod (crankshaft) they are all connected to. The spinning crankshaft connect to your wheels through other gears and rods and makes the wheels turn.
The amount of pressure created by the explosion in the little chamber while the rod is all the way up is compression. If something creates a leak in the chamber, such that the explosion is not creating enough pressure against the moving rod, then you lose compression. Then the engine no go no mo’.
A “compressor failure”, or no compression? On a car like the Versa, the only compressor is the air conditioner, which is driven by the engine. If the compressor were seized, then it *could* prevent the engine from rotating. However, this is unlikely since there’s usually a clutch that will allow the compressor to disengage when the AC is off. It’s likely that you have a compression issue, meaning one or more of the cylinders are not getting sufficient compression. The cylinder needs the air/fuel mixture to be compressed in order to generate power.
