Ford Ranger Lighting and Electrical Problems
My dome lite stays on when my 1997 Ford Ranger is started and the cabin temperature is higher than the outside temp. Spraying chemicals in the door latch is not a fix.

Ok, I have some type of electrical short somewhere. I try to crank the engine and sometimes it starts and sometimes it doesn't. If it does not start, I keep trying it will start after a couple trys. The air conditoning system is not working ever. Had the compressor checked and it is fine, mechanic said electrical problem...and these two things are related.
Ordered a shop manual CD for it, but was wondering if someone had any ideas on what to check? I can drive it, but it is so freaking hot here now. Plus on a budget, ...
thanks
However if the AC compressor problem is indeed related (both problems surfaced at the same time?) then it is not the starter and just a bad wiring contact problem somewhere. Shop manuals would indeed be invaluable for tracking this down.
1. Tacho Meter does not work
2. Temperature Gauge does not work
3. a/c does not come on
4. sometimes it does not start, when turning key there is nothing. Keep trying though and it will start up fine after a couple times. This only happens once in a while, not every time I try to start it.
I was thinking of taking to ford to get a diagnostic test done to have them find the problem at least. On a tight budget though, and have the shop manual now but it is for all the truck engines and hard to sort through it all.
Frustrated, and broke..

Thanks.
I just spent an hour figuring that out after my 99 Ranger failed NJ inspection for the high brake light. While removing the fixture, I saw that one of the clear lights was also burned out. Hell, I didn't even know these lights were there!
They go on ONLY when you roll the dashboard light all the way up to MAXIMUM and then a bit more until it CLICKS. THEN, and only then, the cargo lights come on. Doesn't matter if the engine is on. The dash dimmer switch controls it. And NO, it ISN'T in the owner's manual.
No wonder Ford's going down the tubes.
Here is a quick check to make sure you dont have any corrosion or loose connection issues on the signal wire to the DRL module. Unplug your DRL module and the Fog lamp relay. DRL module is located down by the dr. fog lamp (under the drivers side head light) attached to body. Probably looks like a relay. The fog lamp relay is located in the battery junction box (see underside of lid for list of contents). See if the high beams come on.
If they come on skip next section and go to bottom.
If they dont illuminate, then get an 1156 or 1157 bulb and start tracing back through the wiring system that left to find where you last have power. The next connection or the wire between the point you last checked and the one where you found power will be your problem area. My personal favorite is to overlay the wire (splice in a new wire through the whole length) and see if the lights work then, before you plug the relay and module back in.
If they come on, plug one thing at a time back in till they quit working. The piece that you plug back in that makes them quit is your problem child. Replace that part. If it is the DRL module, verify no water in the wiring, and add more dielectric grease to the front and backside of the connector to prevent future concerns.
Think you can do this?
Anyone know how to get this to work without blinking when the turn signal is on?
Any help would be great. Thanks
Sounds like you got a vacuum leak or exhaust leak to me, but get me a CODE to cross reference..
The vacuum leak would allow excess air into the combustion chamber effectively making the mixture lean..
An exhaust leak would allow air into the exhaust and thus the O2 sensor would read lean as there is too much oxygen in the exhaust stream..

Back to why the CEL doesnt work..
First, the PCM grounds that circuit (which is pin 2 at the PCM) to turn on the bulb. The fuse for the cluster #11 in the fuse panel (7.5A) is what provides the power to that light.
However it also provides power for your oil pressure gauge, charge gauge, and Tachometer. If those things are working, then you have a problem with your printed circuit on the back of your cluster. You already stated you dont have 12v to that bulb during initial key on.
Let me know if the Charge, Tach, and Oil Pressure gauges are working. If they are, you need a new pinted circuit..

So basically what you have told me is that there is no possible way it can be any of the following:
-Printed Circuit
-Bulb for CEL
-Power to the bulb for CEL
Guess what is left in the equation.. The PCM, because it supplies the ground for the CEL. I would see if you can supply a seperate ground for that light during the KOEO sequence.. Thats key on, engine off. Power cycle the ignition like you are goin to start the truck, with your ground attached to the ground for that bulb.. If it lights up with the extra ground supplied, then check to see if you have power on the ground side of that bulb.. It should be dead during the power cycle.. If its not, fix the short to power.. If it is dead, its probably a new PCM for you..
LIGHT SWITCH WERE IT'S MOUNTED DEPENDS ON IF YOU HAVE A STICK SHIFT OR AUTOMATIC, THESE ARE THE ONLY COMPONETS ( OTHER THAN WIRING ) THAT OPERATE YOUR BACK-UP LIGHTS.
GOOD LUCK
I tried using it once with no luck. After I had been on the road for a while longer I tried it again and it worked, but ever since then it hasn't worked again.
I have a 93 ranger that was having an issue with the battery, changed battery out, hit ignition and now there is no juice anywhere, no dome lights, panel chimes, start or anything, fuses look good..... what happened?
