Slightly different A/C blower problem

The fan operates very slowly in switch positions 1, 2 & 3 and blows hard in high. Do you think this is a blower resistor problem? Wondering out loud before getting soaked by the dealer. Thanks.

 

Have you checked the cabin air filter? If it’s dirty it will restrict a bunch of air flow

 

Check the electrical plug going in to fan motor. Mine was doing same thing, and stop working altogether sometimes. The plug and one wire was bad. Rewired a new plug in and haven’t had the problem since. Matter of fact, getting ready to do my son’s motor also.
