How do you know if you have a bad door jam switch?
I have a 1987 Ford F250 Regular Cab 2w drive with 4.9 engine inline six.
I noticed the dome light was burned out so I bought a new one and install it. The light stays on when the door is closed and will not go off by itself. I have to burn my fingers to remove the bulb so that the battery stays strong.
Do I have a bad door jam switch or how do I fine the problem? Any help would be appreciated.....thanks!
The door jam switch completes the circuit to ground to make the light come on. It sounds like the wire has come off the back of one of the switches and is touching something metal inside the door jam. Check both door switches. HTH. -Jim
One door jam switch has three wires attached but the other switch only has two wires attached. The red wire is not attached on the one with two wires. Does that mean that the loose wire is down inside the wall by the front fender and if so, how do you get it out to attach?
It could be. On some vehicles the third wire, on the driver's side, is for the key in the ignition warning buzzer. The passenger's side may not have a third wire. To get to the wires you'll have to remove the kick panel below the dash just in front of the door jam. HTH. -Jim
The switches were corroded and I cleaned them. They were not making contact and now they are working. Thanks for the feedback guys!
You're welcome. Glad to help. Glad you fixed it! -Jim
