GM techs: Replacing Throttle contol module in a Trailblazer
My Dads trailblazer had the throttle control module go bad techs are saying when you replace the control module do you have to reprogram the ECM? Or is the the dealer trying to make extra money ?
extra money, the throttle body went out on my boss's trailblazer a couple of months back and we replaced it with just the battery disconnected while the key was in the "on" position...
