Found this on testing CTM output for left headlight...drivers side from a post of a 2001 Durango which had a flickering low beam headlight issue.
"First, starting in 2001 the headlights have independent outputs from the CTM (Central Timer Module). So it is possible that the CTM has a bad left/low output. The CTM is located under the driver's side kick panel (the plastic cover west of the E-brake pedal).. Remove that cover (pull up the door sill to find one screw, and the other screw is under a tab of carpet at the firewall) and find the Purple/White wire at pin 4 of connector 3 (bottom) of the black box. CAREFULLY stick a straightened paper clip into the wire cavity of the connector - MAKE ABSOLUTELY SURE IT IS GOING IN WITH THE PURPLE/WHITE WIRE OR YOU CAN DESTROY THE MODULE! MAKE SURE YOU DO NOT TOUCH THE PAPER CLIP TO GROUND OR THERE WILL BE FIREWORKS AND YOU WILL DESTROY THE MODULE! - and connect your test light there with the headlights on. If the test light still flickers, replace the CTM."
I'm not comfortable with this paper clip method. I'm still confused about some things. I am getting conflicting advice on different boards. I'm not a mechanic so please talk to me like I'm a child.
Ok, I think I'm correct in that nothing in the interior fuse box is the problem. Is that right?
Ive attached a photo of the under the hood fuse box. I drew a red outline around CTM A and CTM B. These are relays, correct? Somebody, possibly you, told me that CTM A is for both driver's side and passengers side headlights, and that CTM B controls their auto shutoff. Is all of this correct?
If the CTM A relay has gone bad, then how is my passenger side headlight working? I tried taking CTM A out and replacing it with a 20 amp relay that I know is good. This did nothing.
i can't recall if I told you about this or not, but I'll ask again either way. A couple nights ago, I found a post on some form or a guy was asking about his 2002 Dodge Durango, just like mine. He said that he's checked the bulbs and his check the headlight connector on his driver side headlight that is out, just like mine. He said the bulbs and the connector were fine. He also said that is driver side brake light was out. No one posted any suggestions on his question. I checked my driver side brake light after reading his post, and it is out. Could the driver side headlight not working and the driver side brake light not working B connected or related to each other in some way?
ok sir, I really do appreciate your continued efforts to help me figure this problem out. I apologize for any redundant questions I'm posting. As I said, I'm not a mechanic. I'm learning this as I go, and sometimes does the technical terms for things get me confused here.
I look forward to your reply, and possibly a potential solution to this annoying problem.
