2007 running board motor

[Justin link]

Hey guys, new to the forum. I hope this is the proper place to post this. I have an 07 denali xl with the articulating running boards. The driver side seems to be sluggish and if the engine is off will not go back in without a hand, but when the engine is on seems to struggle less. I a guessing the motor is probably starting to wear out. Does anyone know the part number to the left side (drivers side) motor? Or any other ideas? Thanks

My Tahoe does the same thing on drivers side. LH side motor part #25971282. Guessing it should be the same motor for denali.

Did you replace the motor?
