Thanks for the post. You have a good point. I just didn't want to pull the cowl cover until my winter maintenance starts in a month and I will have the car apart and off the road all winter. Just lining up my ducks for the winter. Maybe I'll pull the siren this week and put it back together minus the siren now. Don't need it to drive it. At least then I'll have a better idea. Thanks for the pics. Our car has always been inside and well cared, only 55k. I have done a lot of preemptive fixes anyway. My RCM was mint on the outside but had those 3 questionable cold solder joints, so I fixed that as well. No car is exempt and these cars are mostly easily and inexpensively repaired. They are built like tanks mechanically!
