I was installing a new head unit the other day, I removed the center console and put the new HU in. Anywase, after I was done installing the head unit I started up the truck and the blinkers wouldn't work. Then I noticed that the back left tail light was out (this taillight is also cracked on the side and it's been raining a little)...

So I removed two of the fuses all the way on the left side under the steering wheel, and they were both fine... plugged them back in started the truck and blinkers were working.

A few hours later I had ran some speaker cables and such, and now once again the blinkers and back left light are out... The stereo also doesn't produce any sound, even though i'm positive I have it connected correctly. I assume this has to do with the electrical problem that is causing the blinkers to go out. I tried taking the fuses in and out again but that didn't fix it this time.

How should I go about troubleshooting this problem? I don't know much at all about cars / trucks mechanically... I was told there was a fuse box in under the hood, should I check that out next?

 

Also, my dome light never worked since I got the truck 4 months ago... It started working now all the sudden

 

Three words: exorcist

No, but, I really am stumped. Sounds like there is obviously a bad connection somewhere. I don't see how the new headunit could cause all these problems.

There are some electrical guru's around here somewheres...

 

yea, and why would removing the unblown fuses and putting them back in fix it temporarily... just wierd... the top left fuse in my fuse box is missing, is that supposed to have one?

 

holy crap, unhook the dimmer (orange) wire NOW!!!!!!!! trust me i did the same mistake and it cost me $5,500 for a new wiring harness and 4 months without a vehicle while a contracted company hand built the harness for toyota because apperently there are zero spare harness in the entire world... (seriously)
dimmer wire

 

thanks for the heads up, i'll check that out tomorrow asap.

 

well I fiddled with the wires again and hooked back up the center console the blinkers work, but the back light is still burn out...

still no radio tho... this sucks
