Ford Ranger / B-Series :: Dimmer Dims Running Lights And Door Ajar On


Apr 16, 2017

Today I've been working on fixing the Door Ajar problem that's developed in my 2002 ranger extended cab. I haven't made any progress taking the main doors apart and testing the switches. Doing a little research on the forum I learned that the door ajar wiring is tied in with the dome/instrument dimmer. Well that's interesting because my instrument dimmer was never worker properly. It dims the running lights instead of anything in the cab, and if I turn it down too low, the fog lights won't function.

So I have a few questions:

+What's the way to determine which door, if any, is sending "door ajar"? I'd rather not take the back doors apart, and check the wiring on each door.
+What's the deal with my dimmer?

Ford Ranger / B-Series :: 2000 - Door Ajar Light Comes On And Overhead Lights Won't Turn Off When It Rains

When it rains my "door ajar" light comes on and the overhead lights won't turn off. that's the common problem. i've read many threads where it says to spray liberally with WD40. i intend to do that but the plot thickens.

Usually, after a few dry days, the light goes off and everything returns to normal. Not so any more. the newest episode entails the light staying on for two weeks of good warm, dry weather. naturally i always take the bulbs out. Now, its somewhat sporadic but.... I'll try to explain since I'm still trying to wrap my mind around it.

1. light stays on, dome lights won't go off.
2. tried dome lights couple of times, still wouldn't go off
3. finally, inserted dome lights and they wouldn't come on (except when manually switched on) however the door ajar switch was still on.
4. EXCEPT when i opened the passenger door the domes came on but wouldn't go off so i took the bulbs out again.
5. that's where i am now.

Not positive but I'm thinking since the new wrinkle in established expectations that I'll probably end up replacing the driver's switch. Before I tear up the door panel i need some hints concerning removal. the door has power windows and locks (which i need new actuators but that's a different story). Is there anything I need to watch out for?

Ford Ranger / B-Series :: 1999 - Door Ajar Light Stuck On

Like the title says, my 99 ranger has the door ajar light stuck on, which in turn is making the dome light stay on. It's kinda been acting up lately, but would go out eventually. Today I washed it and had the doors open for a while. After I shut the doors and started it the light stayed on and hasn't gone off since. I pulled the negative cable tonight. And no, the doors aren't open! FWIW I cant pull the doors any tighter closed and make the light go out..

Ford Ranger / B-Series :: 1999 - Door Ajar Light Stays On

In the past week after work the door ajar light comes on and stays on. I've checked all doors and they are not ajar. The dome light comes on when i start the engine and goes off after a few seconds, but only when i have this door ajar problem. After I get home and shut off the engine for about 30 seconds, then restart, the dome light nor the door ajar don't come on.

Ford Ranger / B-Series :: 1999 - Running Lights Will Not Turn On

I recently replaced all my incandescent lights on my 99 ford ranger which makes my truck stand out, but the issue I am having is all my exterior lights work including my turn lights but my running lights will not turn on. Is there any way I can fix this problem. I changed my flasher unit with one that is LED Capatable and i added load equalizers to the back to correct the issue with my turn signals but i just cant get my running lights to work....

Prius (2010-12) :: Brake Pump Dims Interior Lights When Open Driver Door

When I open the driver door at night, the brake pump would dim the interior lights a little while running. Is this normal for a 6 month-old aux battery? All my trips are 30 mins or longer so it has plenty of opportunity to recharge.

Ford 7.3L Power Stroke (1999-2003) :: Door Ajar Light Stays On All The Time When Engine Is Running

Here are some signs of the problem.

*Key fob does not work - battery is good.
*Interior overhead light works only on manual.
*Driver's auto door lock (with driver door open) will lock all four doors but the driver's door will automatically open back. To secure the truck I manually lock the driver's door.
*I replaced the driver's door 'ajar switch' with no results. The old switch was good after testing - normally closed until the ball is depressed then it goes to open.
*No codes.
*I just checked all the mini-fuses with a VOM and they are good.
*Could one of the relays be part of the problem?

I am curious if there is a scanner that can identify the bad door ajar switch if any?

From what I have read so far it appears the VSM (Vehicle Security Module) may be bad as a many of these 2002's complain of this problem and the VSM generally solves the issues. Are there folks other than the dealerships that can program the module if I purchase a new one and remove the old OEM one? Other than the inconvenience the truck runs fine other wise.

Ford F-150 (2009-2014) :: Passenger Door Ajar On Dash Display / Interior Lights Stay On / Drains Battery

The Issue: Dash display reads "Passenger Door Ajar", interior lights stay on, drains battery

Current Fixes I've completed
Sprayed electrical cleaner in all 4 door latch assemblies (didn't work)
Relubricated all 4 door latch assemblies with food grade lithium grease (didn't work)
Replaced passenger door full latch assembly (didn't work)

What is my next step? I have noticed that if I wedge the door lock button on the driver's side door into the lock position, the door ajar message turns off and stays off? I was thinking wiring or relay issues?

Lexus GX 2004-09 :: Door Ajar Overhead Lights Come On And Within A Few Seconds Both Go Out

both this winter and last winter as it gets colder my GX will indicate that a door is ajar and the overhead lights come on and then within a few seconds they both go out. this seems to occur when accelerating from a stop and resolves once the vehicle gets over about 15 mph. in my estimation this seems to be related to the rear cargo door as if it partially opens just enough to let the sensor knows its slightly open. the dealer has been unable to duplicate it and it only happens when its around freezing or lower.

Century :: 2004 - Door Ajar Light Came On But Interior Lights Will Not Turn Off

Okay, so the door ajar light came on the other day and the interior lights would not turn off when I turned off the car. This is a 2004 Century. I ended up removing the fuse so that I can be assured that the battery wouldn't drain. The problem is in either the driver or left passenger door. I couldn't see any door switches like I've seen on other vehicles so I'm wondering if this is a latch issue or an electrical issue.

Lexus GX 2004-09 :: 2003 GX470 - Interior Lights And Door Ajar Light Comes On During Acceleration

Like the subject says, I have been noticing over the last 2 months in my 03 GX470 that the interior lights and open door dash light come on when accelerating.

-The issue is exacerbated in cold weather. I have double checked all doors and rear hatch are closed.
-I have gone around and checked all door sensors are functioning, not sticky, etc.
-I climbed in the rear hatch and had my wife shut it. When I push on the plastic under the window, the lights come on. When I push on the glass itself (and push MUCH harder then on the plastic) the lights do not come on.

Clearly I have an issue in the rear hatch trim area.

Ford Ranger / B-Series :: 1986 - Gas Will Not Keep Engine Running

1986 Ford Ranger / 2.3 EFI / 140 CID OHC /4-Cyl/5 speed

So the last time I was here, I was having doggy issues which I thought were fuel related. I'm still having issues, although it appeared to cleared up a bit.

When I start the engine, it cranks over, I'd give it some gas, it would rev up, then suddenly die, no matter if I pressed down on the gas pedal or not. After two or three times doing this, it would turn over and maintain a steady idle, then off I go.........

The problem now? Well, late today I tried to get it going, and after about 15 times, I gave up. It would not stay idling, it would crank over then die. I did not want to ruin the starter. It seems the gas pedal is worthless after the engine decides to conk out, and no matter how many times I step on the gas pedal, nothing happens.

Has been replaced within the last few months:

Fuel filter regulator,
Inline fuel filter,
Cap and rotor,
Lucas fuel injector cleaner,
ECC computer, and Fuel relay switches, (multi-function relay/connector switch)
Air Control Valve - Removed and cleaned.
Checked all vacuum hoses.

Has not been replaced:

Map Sensor, (was told it's located on Pass. fender wall, but can't find it, according to the manual)
EGR Valve and sensor,
Throttle Position Sensor,
EVP sensor,
Spark plugs, (two years ago)
Plug wires, (two years ago)
Ignition control module, (replaced about six years, or more)

With trying to keep the gas going to turn it over, it does not, so to me, it seems to be more of a fuel problem than electrical, but I'm no mechanic.

Ford Ranger / B-Series :: 1994 - Battery Keeps Running Down

Got a problem with the '94 Ranger. Something keeps draining the battery. For reference, the truck is an XL, manual 4x4, 4.0L, 5-speed. I've been trying to keep driving it so I could try and diagnose the issue. At first, as long as I cranked it every day, it stayed charged up, but now it has gotten worse. It will run down in an hour or two. I know figuring this kind of problem out is tough, but I thought maybe some others of you may have experience in this area that might benefit me.

Based on a gut feeling, my first idea was that there was something going on inside the AC compressor. So, I disconnected the compressor, but that wasn't it. My plan at the moment is to replace the wiring harness between the battery and the starter. The current harness is pieced together (not my doing), and whether it fixes this problem or not, it needs to be done. Another thing I've thought about is the ignition switch. It acts "funny" to me, but it has never really given any trouble.

My son needs to take this vehicle back to college with him in a couple weeks, and I need to get it figured out.

Ford Ranger / B-Series :: Running The Engine For AC - ABS Light Came On

So I'm sitting in my 99 2.5L at work while we are empty, running the engine for A/C because it's quite hot out. The truck was running for a half an hour or so, not moving, and I look up from my phone at my dash, to see a brand new ABS light on....

So I've pulled out my handy code reader, but no ABS codes have arrived. Maybe my reader can't read it, or maybe I need to drive. But what could this be? And is it safe to drive the truck home tonight? Pedal pressure still feels normal.
