I seem to be having a series of problems related to the driver's side junction box that is affecting the stereo, clock, and oddly enough the key and seatbelt buzzers.
Upon examining the electrical diagrams I've determined that it may have something to do with the vehicle's "Integration Relay" as the problem is not affecting the cigarette lighter which is connected in parallel through the bus across the IR. All 3 of the other symptoms show tie in through the IR, hence my suspicion of this part.
This all began yesterday when I attempted to remove my Sirius tuner module for warranty service. After removing the module, I attempted to reinstall the headunit back into the dash. As I customarily do when reinstalling the HU, I turned the keyswitch on to make sure that the system was powered before buttoning up the console. The stereo would not power up and the digital clock would not function either.
Today I realized that both the seatbelt indicators (both visual and audio) as well as the key reminder buzzer were not functional. All other functions seem to be fine, but it seems everything running off the CIG-RAD fuse section (aside from the cigarette lighter) is dead. I checked the fuse and it seems to be fine. I did do a brief continuity check through the aftermarket and OEM harnesses and connections. There don't appear to be any shorts ahead of the main Instrument panel harness behind the cluster. I didn't want to get too deep into the diagram, nor the fuse blocks themselves until I ran this by some more folks for feedback.
Has anyone ever heard of a sectional failure of the Integration Relay affecting only one section of the fuse bus?
Does anyone know how much something like is going to cost to replace since it would seem the IR and fuse bus are one continuous unit?
Is it possible that this can be attributed to something simpler than the above mentioned hypothesis?
Thanks for your help!
