    already tried that, nothing for the defogger but a 30amp fuse - and it appears to be alright. I also checked the fuse box under the hood, again nothing there for the defogger.

    The fuse is good, I'm picking up a new meter this weekend - I lost the manual that came with the old one and I don't know how to use it - I think it's a Sperry SP5A or something.
    Thanks for checking on the relay, I called the dealer, they said they think the relay is built into the switch, but that doesn't sound right to me. I have a Chiltons manual, but it isn't much help. I'll let you know how the test comes out this weekend.

    Again, Thank you for your help.

    I've got very little power going to the rear window, it barely moves the needle when it's set at 10 volts (I think it's 10 volts - I lost the manual).
