maintenance problems

My back windshield defogger doesn't work and the light on the dash comes on and the metal strips tested ok with a test set about a year ago but it doesn't take the fog away. I was told to check the two connections on either side which I will do but are there any other suggestions out there? Also my remote control doesn't work any more and I was told to go to subaruparts.com and order another remote transmitter, is this the best parts store to go with?
