Running board malfunctioning


Recommended Posts

I’m all over it.   Been using on blaster for a week. They function,  then get stuck.  For 6 months they run great and now last two weeks go up half way then back down or stick every day.  
 

does it make sense to power wash joints then use penetrating oil or just penetrating oil and push and pull on the running board to free-up and function as designed ??

Power wash could help. I would shut off the dash switch and give it enough time to dry the electronics/motor out. Compressed air may help. I've had some that just could not be brought back to full  functionality. Very expsensive to fix.
