From water pump to SRS

I found the chattering relay - it's in the rear fuse / Relay panel, behind the LR tail light. The one on the very top row and the only one on the top row. Now to find out what that relay does, and if it's the relay or something controlling it..

owners manual will show what the relay is for.

I swapped relays and it's not that one. When the turn signals behave, there is no noise coming from that relay. I think it's for the locking system. So now to find what controls that relay, that also affects the window motors, and the turn signals.

to answer that you need the circuit diagrams, google for it or use vida to see. try this, I don't know what yr it covers.

In front of the LR tail light, hopefully.

Yeah - from sitting inside the car perspective

. It's not the relay itself, but something that controls it. I have a problem with the passenger door not locking - that microswitch, but I can't see how that would cause all of these other problems. I also checked my battery and its healthy and fully charges. I just wantt o find the problem before I get the SRS code reset..

it could be putting noise into the door security signal wire, confusing the ECM.

I'll read the schematic again - I missed the radio is also affected. I hear a relay click from behind the center console (radio and HVAC controls) and the radio comes on and the turn signals / windows work fine. the they don't. No pattern to it at all.

If I don't find it today, I will get a full code read tomorrow. Of course the car will work great as soon as it's plugged up..
