I need some help here...
I am now on my 5th "bad" block heater and this time dealer is refusing to replace it saying it is not suppose to come on till the outside temp is 0 degrees. ( I am not kidding.... )
They even gave it to me in some bs paperwork from GM...
I told the dealer it is easy for me since this is the 5th time the block heater has gone bad...
1) When I plug it in EVERY night I hear a spark at the extention cord as it is plugged in... Dealer says I am nuts, and I should not hear that at all...DOES ANYONE ELSE HERE IT SPARK WHEN THEY PLUG IT IN???
2) I told dealer in the morning if I did not hear it spark, the glo plug indiciator on the dashboard will come on for several seconds while it warms them up, and if working it doesnt come on at all...Dealer told me I am wrong again...
ANYONE ELSE NOTICE THIS ABOUT THE GLO PLUGS WHEN BLOCK HEARTER IS USED?
3) I told the dealer the extension cord in the moring is limp and warm from it "running" current all night and when the block heater quits, cord stays cold and so does motor...AM I THE ONLY OWNER OF A GMC SEIRRA that the block hearter has ever failed on???
