burnt plug

Honestly, I'm wondering who's really to blame here - did GM use a connector they knew to be inadequate? Or did the supplier(Delphi most likely) rate it to handle 30 amps without enough testing? Sort of inclined to blame GM - I've seen this on my '79 Monte Carlo too with the main power feed to the blower motor. To be fair I've also seen it with the headlight ground wire on my sister's '99 Mitsu Galant (too small of a wire, which melted itself and the connector after a while. I'd imagine Mitsubishi realized this because the dealer's replacement plug/pigtail harness had 14 gauge wires, where the original wires on the car were 18 gauge.C Renner's Auto Electronix

it's GM's fault all the way. Delphi builds connectors/ harnesses for tons of stuff out there including construction equipment and commercial trucks, you know whats funny? the connectors on all that other stuff works, you see failures like these on GM's all the time. GM's engineers (haha! my ***) decide how heavy of a wire, what kind of terminal and connector is needed for any given circuit. that info is only given to Delphi and they build it to GM's specs. GM decides not Delphi. Delphi is only the suppling vendor. Why would GM try and use the lightest wire and connectors/terminals as they can (somewhat) get away with? it costs less. 70% or maybe more of almost any GM out on the road has this same problem with fuel pump connectors at the pump, they have for years.
