Was just playing with the fan speeds and noticed that there is no speed increase from speed 4 up to 5 and the is no decrease from 5 to 4 but all other speeds have a noticeable difference. I checked the plug at the blower and that is good.

Re: HVAC blower?
there aren't just 4 or 5 blower speeds -
the blower speed is controled by signal voltage -
each 1/10 of a volt changes the blower speed slightly -
you may or may not feel/hear a difference with each change -

Then as long as its working I won't worry about it.
