My rear window defroster is not working. I push the button on the dash & the light comes on. There is no power to the fuse to the rear defogger under the rear driver side passenger seat.

I am also having problems with my stereo speakers cutting in & out.

Previous owner or some also replaced the wiring to the sunroof.

Could this all be a connected problem? A bad ground?

Please help. Thanks!

I don't have the drawings with me, but that might be a bad relay.

Normally, the switch in the dash operates a relay that switches the circuit to the defrost element.

Check your fuse panel covers (or owner's manual) for the relay location. compare the other relays, one might be a match, swap in the 2nd relay to test the circuit
