Hi All!
My remotes for the 2000 GMC Sierra are pretty weak. They must be right at the truck for any action to take place. They are the 3 button style (unlock, lock & panic). I tried new batteries with no luck. Both developed this problem at the same time.

My guess is that the connection for the receiving antenna is corroded. (Just a guess) But, I sure can't find it. Do you all know where it is- or have any ideas what the problem really might be? I have a pdf of a service manual, but could not find details in there.

Thanks For Helping!
Paul
