06 H3 Door alarm sensors... Which ones?
Question for the H3 Guru's here. So it seems one or more of my door sensors has failed.
How can I test to isolate which one to change out?
THANK YOU

Hey Woody,
I use a paper clip as a jumper. Just leave door open carefully remove switch and don't let wires fall inside. Once jumpered lights inside should go out.
Toss the switch on a DVM set to ohms and verify you're getting a proper connection internally. Closed low resistance. Open high resistance. Use contact cleaner on each switch and retest if necessary.

So meantime. Will do some continuity testing and see what can be found. Maybe one of my switches is just fouled.
Do appreciate your reply.

Problem solved. The tail gate door switch had corrosion on the contacts.
CRC QD spray and some q tips and tooth pics to the rescue.
Each switch had some carbon. Only one switch had enough to cause the "open circuit" that caused the false door alarms to the DIC and totally crazy audible and lock operation conditions.

Welcome buddy...
Glad I got the 2 replacements from amazon for about $16.
The tailgate switch failed after my last trip surf fishing. (Salt water corrosion) So I replaced that one for the win.
