I recently installed an AUX GM aux input adapter in our 2004 Envoy XL. Every thing worked fine for about a week then the lock remotes stopped working. I changed the batteries in the remotes and tried reprogramming the remotes and still they did not work. Then I noticed that the rear window wiper was not working and when I hit the auto door locks the rear gate did not lock as well. I checked all fuses and did not find any bad. I do not know how to check the relays. I have since removed the AUX GM and nothing changed so I guess that was not the problem. I pulled the rear gate apart and noted that some of the wires have power.
Does anyone have any ideas. Where can you buy relays or is that likely not the problem.
Thanks,
Bruce
