Thread: rumble and screech 06 gxp monsoon

getting extreme rumble and screech from front center dash area of 06 gxp when i go over sharp bumps/a good slap to the console shuts it up for awhile/can't take to local chevy dealer, ex-wife works there/
ideas?

grounding issue?

Find another dealership?

probably a ground, and i'm too old and fat to get under the dash anymore

will go to another dealer out of town, i suppose

thanks
