    Before you replace it try a jumper wire between the two contacts in harness. Then turn key on and get beeper going. Wiggle all the wires and see if alarm is constant. Or drive it to really be sure. Good idea to eliminate any wire problems.

    Agree! I always like to PROVE something is bad before replacing it. It sure suck to spend $125 on a switch and the same amount on labor only to find the problem was a loose connection back at the back-up alarm.

    And don't toss that old switch till you do test it. Being it works off restively low pressures I'd try hooking it up to an adjustable air regulator, say like one used for a paint gun and run it through the on off cycle several times while tapping on it with a small hammer.

    And if in fact it is bad don't toss it till you cut off the Deutch connector and put it in your electrical parts box. Never can tell when that one will come in handy!
