Newly purchased '99 4Runner with some electrical issues.

My boyfriend got this 4runner for me from a junkyard, so we know nothing of its history besides the obvious. lol I have issues with the power to the stereo and basically anything linked to the acc fuse under the dash. I have replaced it. There was a viper alarm in it that was already disconnected when I got the truck. Looks like someone cut it with a knife.. I do not know where it was connected to the vehicle even though I have taken apart a majority of the dash. The acc says it also is part of the power for the alarm so wondering if its linked to my issues with how certain electrical items do not work. I don't know if there is a fuse somewhere that I'm not finding since there is a large area that is not very accessible without tearing out the complete dash area...

Another issue is that my dome lights were working n now they have stopped working with the doors unless the key is on...


Hoping someone else has come across this issue with their Runner.. Thanks in advance... Jennifer

Ok clarification....

Not a factory stereo. There is no power to the all time power line so I ended up running a cheater to the fuse box to get power. This is spliced into the dead hot line which is still connected like it was hot. The person who had the runner before me had also run a cheater but hadn't used the matching connectors to the original Toyota connectors that r unplugged from the factory amp. I had rewired the hack job back to the correct connectors n swapped the non factory stereo it came with to another non factory stereo that was from another runner with the proper connectors. Without the cheater I have no power in any position.

The dome problem started during the taking apart of the dash n replacement of the stereo. If key is in any power position I will get dome lights..

Yes I have a multimeter... I used a test light on the pins to verify power. It was a lien sale due to it being towed... Runs great..Just passed a smog with 222,000 miles.. :)

I also only have power to the cig lighter n power ports when the key is in power positions. No clock at all but I may have found that issue in another post.. Checking the connectors for it tomorrow.

Jennifer - Welcome to T4R.org. Can you clarify your problem? You have a factory stereo and when the ignition switch is in the ACC position, the stereo doesn't power up, correct? How about when the ignition switch is in the ON position? (page 88 in the 2001 Toyota 4Runner's Owner's Manual).

The dome problem occurred after you made a change, what change did you make?

Do you have a multimeter? Why did the 4Runner end up at the salvage yard, wrecked, bad tranny/engine, other?

Not sure if this is in your wheelhouse but to successfully troubleshoot electrical problem, you need to be proficient with a multimeter.
 
Thank you for the welcome.... I edited my original post with the info you requested. N thanks for the link on the multi.... Im ok with one but this will definitely be helpful..
 
I know in my 97 the factory cig lighter wire is only hot when the ignition is on, so that may not be a problem at all if the 99 is the same.

As far as the electrical problems go, have you pulled off the driver's side kick panel? Most of the interior wiring runs through right behind the panel, and I know mine has remnants of an aftermarket alarm behind it, so that may be where your problem lies.
 
Well I did bunch of reading last nite on this forum n found the radio/light issue.. It was the dome fuse under the hood... N I thought I had gone thru all those fuses but I'm guessing I didn't... So replaced the fuse n disconnected my cheater wire for stereo power n the stereo n door lights work like the should :) Thanks for all the wiring diagram links on here cuz they r way better than the book I bought...

Still don't know about the clock till I pull open part of the dash.. Later today.. The fuses was a quick fix. ;)

And I believe your right about the cig lighter only working with the key in a on position.. Also the same with my extra ports. Would be nice if at least one of them worked all time.. I have had most of the dash apart from the fuse area to under the gauges. I found the alarm under them. I removed it for now with enough wire n such left over to put it back if I ever want it. But would need to get the little alarm things first. All I got was a single key. I have ordered another key from Toyota n will have it next week..

So now to wait for my new headlight switch cuz its bad after multiple checks n changing out relays n such....

Have a great day I'm of to go deal with my critters.... Hoping my clock works after I check where its plugged into...
 
Shadance - Nice troubleshooting. If you need a headlight switch, I have one. I added factory fog lights to my 2001 4Runner and changed headlight switch. No charge for the headlight switch, just pay USPS shipping which wound't be too much. If you or a family member served in the military, I'll pay shipping.

So if you don't have a fog light ring on your headlight switch, my 2001 switch should fit your 1999. The switch is a known good.

Some other thoughts, search the forum for pink milkshake. Also if you have to replace dash bulbs, consider LED.

Thanks for the offer of the switch but I also have foglights... I actually tried to use the non fog light switch from another n it didn't fit.

N yes led is the way to go for lighting. But that will have to wait till all my little issues r fixed.. ;)
