Can someone please tell me where it is located? I bought the relay but can't find where it goes. Thanks!

 

Welcome to the forum....
I don't have my documents available at the moment to verify, but it should be in the under hood fuse and relay center....

 

nope not under hood all that I can find under hood is the 30 amp fuse for the circuit. there are a couple of relays under hood in fuse box but nothing for the rear window defrost. anybody else have some ideas? I have a 1999 k1500 suburban cannot find the relay either.
