Hey....

Brooklyn '07 Ranger owner here...





all of the sudden a couple of weeks ago, after turning the truck off (at a delivery) and turning it back on, I had no dashlights, headlights (was daylight at the time), cigarette lighter power (I run an inverter to power external music/studio monitors)....all turn signals and hazards work.... in fact, my door ajar signal has been dysfunctional for a while now. It always stays on... the dash lights are off, but that indicator remains on. truck starts up fine, blower/heater works, power windows work, windshield wipers work...

and THEN...all of the sudden, sometimes after a time driving it will all come back on again...everything working fine. It hasn't turned off while the truck is running, but the problem is now a tossup as to whether I will be able to drive (at night, or during rain) until I start it up,. Sometimes I start it up and everything works fine.

I'm going to do some research, but if someone can help guide me toward trying to figure out the solution, I'd greatly appreciate it.

I've seen a lot about fuses, but don't fuses just blow when it's their time? and then not work again? what type of problem would hinder the power to all these functions at once and be finnicky and just work all of the sudden sometimes?

also, the cigarette lighter in my truck will run power even while the truck is off generally (I've run the battery down by accident before doing so), so it makes me think there is some fault from the battery to the main power console? (or whatever it may be called) to which the headlights, radio, cigarette, etc. are then connected...

thanks in advance for any responses...

I have an 01 and my cigarette lighter is always on. If anything just disconnect it but check grounds and positive terminal

Find the associated fuses in the interior fuse panel. When the lights go out, remove the fuses and check the feed leg for power. If there is no power present, check to make sure the common power feed is okay. Since it kills a lot of items at once, it sounds like a loose main feed into your truck. You may have an issue with the engine-interior harness plug that runs through the firewall. You may also have an issue in your fuse box. You're just going to have to use a multimeter and work your way back from the components to the source. Find the spot that still has power, verify the next position down doesn't then inspect everything in between.

So if your main fuse in the engine bay was good, and the panel fuses in the truck had no power, check the engine-interior harness connector. If you have power there, work your way back into the interior panel for issues. If you don't have power there, work your way back to the engine bay fuse panel.

Don't bother looking for 1st gear synchros, I bought the last one

so...excuse me for not taking the time to thank those who responded....

your input was helpful...

I ended up going to a shop that specializes in sound systems since they know their way around electric...

they charged me I think 175 for the diagnostic... I suppose I could have figured it out myself, but this was keeping me from driving and doing work with the truck, so I went with the pro solution...

anyways...as some stated, it was the smart junction box...there was corrosion on some of the connectors there... the guy said that it needed to be replaced and that only shops that specialize in reprogramming computers or something could do it...so, the part is going bad...

what he did do is clean all the connections up with some sort of spray electrical cleaner (he said NOT to use dialectric grease, cause it would not help, although I'm not sure that makes sense)... and after he did that...it worked fine, and has continued to work fine since....

when it happens again, at least I know what the culprit is...
