Something like a burned fuse link wire then.

Di you know what the resistance for the grid should be so folks could
meter it to see if it is still good?

I'll bet a $2.00 piece of resistor wire and a couple crimps is a pile
cheaper than a new unit.

the thing i check for is continutity in the grid not so much for resistence because i
know it's there on one wire and thats with the seat intact if the npc is bad the drb has a
fault recorded in the memory seat module
the replacement grid is only 25.00 us dollars for that year
and just recently i have been using the grids for 2002 and 2003 on the 2000 grands that
require the whole dam 800 dollar cover but you must remove the padding to get some kind of
warmth thru the cover
i would think the krimp on connectors would wear thru the seat cover or at least be a bump
were there was not one before
