Are these lubrication points on my blower motor, or something else? 53 Cavalier

Those are just rivets and there is no provision for lubricating the bushing at that end of the motor other than disassembling.

The bearings are supposed to be lubed for life but I guess as things go 75 years or so could be a lifetime. While it is not really recommended, rather than disassembling I have read of people carefully drilling a very small hole directly on the end or top of the bump and using a needle applicator to add a drop or two of oil at the end of the shaft. If you do that be careful not to drill deep or add more than a drop or two as too much oil will leak out and cause issues with the brushes and commutator.

Thank you!

Speaking from experience you can disassemble the motor but the fan will nearly always be rusted onto the shaft and completely inseparable, so the process is convoluted. If you really want to let me know and I'll add more detail.

Also: If you do the micro-drill and lube through the housing shaft cover "bump"...remember to tilt the bump up when done, then wipe it down with alcohol and dry it...then put a dab off 2-part epoxy/JB weld (after it just starts hardening) over the hole to keep the oil from weeping back out onto precious upholstery/carpet/etc...if you need to lube it (in another 75 years), just knock the epoxy bead off and repeat
