Heated seats

[RCMerrill]

my 06 has heated seats but sometimes the drivers side doesnt work but the pasangers does a year ago they both stop working & later found the batterys were bad after they were changed the seats worked fearslessly. i am not sure what to do next. can the cold weather or switch be the problem ?

Get out the test light and check connection, but for heavens sake ( and your trucks wiring ) don't poke holes in the wires or you WILL have lots more problems. David
