Re: Switch at the base of the bed

On our '89 GV the outlet box for the block heater was in the engine compartment, accessible thru the driver's side grill door. The switch was on the end of the bed towards the pass side, with a red light internally when the switch is on.
Please pull the block heater plug out of the outlet, check the condition, and then proceed to clean the blades on the plug. Ours, it turned out, were so corroded that the plug and outlet melted together!! Narrowly averted a major fire!!
