Does it have DRL lights? Does it have quad headlights?
Do you have a wiring diagram for the low beams?
Hello, my name is ***** ***** I am sorry that you are not getting an answer. Your truck has a CTM (Central Timer Module ) instead of a FCM. The CTM is mounted under the dash to the right of the steering column. It is a black medium sized module. Let me know if you find it.
The module controls interior lighting, and can flash the headlamps for the factory security system, but does not directly control the low beams. That did not happen until 2002.
Click on the link below to see the headlight diagram. The switch actually grounds the circuit. After it passes through the high beam switch.
Positive battery voltage goes to each bulb. Then the ground side goes back through the high beam switch, then to the headlight switch. When the switch is turned on, it completes the circuit by grounding it. Look at the wiring diagram. Then you will understand.
Gotcha. Well if you start by using a 12 volt test light and check for voltage at the headlight bulb connector and have voltage, then follow the diagram back through the high beam switch and then to the headlight switch. You should be able to find the problem. Check that connector at the high beam multifunction switch. I have seen issues there in the past.
I hope that this information is helpful and please don't forget to rate my service using the just answer star rating system. I would really appreciate it. I will still be able to help you out even after you rate me.
No, the ECM is for engine systems only. I bet that the problem is up at the multifunction high beam switch on the steering column.
Yes. Are the wires and terminals in that connector ok?
Ok, let me check a few things and get back to you
Ok, what I want you or your mechanic to do is to gain access to that connector that plugs into the multifunction switch and get a jumper wire. Ground one end of the jumper wire, and then touch the other end to the multifunction connector terminal # 18. It is a Violet wire with a White stripe. That should make the right side low beam come on. Try that and let me know if it comes on.
No problem. The connector that plugs into the dimmer switch (also known as the multifunction switch) There should be a Violet wire with a White stripe on it. If you ground that wire's terminal, the right low beam should turn on. Hope that helps,
You are welcome. Let me know how it goes!
