problem #2

Jul 012013

Impala LTZ

  • Automatic transmission
  • 52,000 miles

actuator under dash knocking when i use my key fob

Every time i hit my unlock button on my key FOB the knocking noise starts under my dash. It will last about a minute. If i go from AC to Defrost it starts again & last about a minute. Very annoying. If it is the vent actuator why does it do it when i unlock or open a door.

problem #1

Impala LS 3.5L V6 Flexfuel

  • Automatic transmission
  • 35,708 miles

First problem for this car that I had got in April, 2010. Not that angry, but it did take over 3 hours at the local chevy dealer to diagnose and repair. I hope all is well from here on.
