2004 gxp HVAC intermittent blower

[FrankAR15]

Fan motor intermittently stops.
Will start/stop when hitting a bump in the road, or kicking the left side of the panel above your feet on the passenger side.
Fan makes a small abnormal noise when running and won't reach the highest blower setting when it is working.

So I'm guessing the problem is the motor itself. I was searching around the forum and I was reading that it also could be the resistor that is next to the motor??
Wondering if anyone could tell for sure by the symptoms...?

I looked around online and the cheapest I found for a GM part was 180 something. Can anyone direct me to anywhere cheaper?
Also I saw a tutorial that seemed pretty simple as a do it yourself, but it wasn't a bonneville GXP. Think it was Buick or a Grand Prix. Anyone have a tutorial on a bonneville GXP?

Thanks for your help

Frank
