Blower fan does not blow very fast, and the hi doesn’t work at all. It seems that position 3’s speed was similar to between 1 & 2 on my last car. Any suggestions on where and what to check?

Thanks

The blower resistor and its harness connector are the most common cause of your problem.  The information in the linked article should help explain and has a lot of test information included.
