Re: Alarm sensitivity?
Same thing happened to my first SRT after a powerwash. Couple things to check before taking to dealer. Both deal with the trunk proximity switch (trunk ajar) located piggyback on the trunk latch. Open the trunk and it's staring at you.
1. moisture in the proximity switch - Fix by blowing an air source into the switch to dry. Water from powerwashing finds its way into the switch causing it to short. Similarly, I have found that the trunk is sealed very well, and any moisture left in the trunk, i.e., wet towels, condenses onto every surface in the trunk, including electrical components. Moist air gets out of the trunk only by leaving it open long enough for dry air to replace it. Moisture will not escape through the seals.
2. proximity switch barely engaged - If your trunk is particularly hard to close, the rubber trunk stop pads that contact the car body may be keeping the switch from fully engaging and need adjustment.
Hope this helps - good luck.
